DISCUSSION: As the sun finally set on the Appalachian Mountains yesterday evening, many people were enveloped in white as there was a solid coating of snow on the ground for many across this region. Having said that, it goes without saying (based on briefly analyzing the graphic attached above) that there was quite a pronounced gradient of snowfall which developed. This gradient in snowfall which is defined by a change in the amount of snowfall over some given distance and often tends to be found over short distances in many cases was most likely the result of "orographic effects."
Orographic effects or what we most often refer to as "orographic lifting" in the meteorological world is best defined as when air parcels are more aggressively forced to rise over some elevated surface (e.g., a plateau or mountain). As this process occurs, more moisture is squeezed out a result of the parcel being forced to expand further and release increased amounts of atmospheric water vapor. Thus, orographic lifting will therefore consequently help a region to receive locally higher precipitation amounts which is precisely what unfolded in this particular case within the NWS Greenville/Spartanburg, South Carolina coverage warning area.

DISCUSSION: As of later in the day on Friday, images were captured from just above the Earth's atmosphere of the current snow cover positioned across the state of California and beyond. As you can clearly see in the graphic above (as provided by the NOAA Satellite and Information Service), there is quite a distinct gradient associated with the relative concentrations of snowfall across many parts of southwestern United States. These vast differences in the extent of the current regional snow pack is chiefly due to the variability in the positions and moisture trajectories associated with each successive Winter-time extratropical low pressure system relative to the positioning of the more elevated regions scattered across the inter-mountain sections of the western and southwestern United States. Having said that, attached above is an image as captured later in the day yesterday of the Golden State as viewed from space this afternoon. California Department of Water Resources reports 186% of normal snow pack for this date statewide. It is worth noting that this an impressive positive departure from the typical snow pack depth which is observed across this part of the United States at this point in the Winter season.

(credit: NWS Morristown, Tennessee)1/23/2017 DISCUSSION: As of earlier this evening, there was a very impressive radar signature observed across portions of eastern Tennessee. If you are wondering the reason for why there was a vortex-type signature by way of the Hytop, Alabama radar site, the answer is attached below courtesy of the National Weather Service office located in Morristown, Tennessee.
Answer: It's the center of a deep low pressure system currently moving (slowly) through the Southern Tennessee Valley. Pressures as low as 984 mb have been recorded in Chattanooga. That's comparable to a strong Category 1 hurricane! Strong, gusty gradient winds in the 30-50 mph will be possible overnight and into the early morning hours, which could produce some sporadic tree damage! Also, moderate to heavy rainfall will produced localized flooding issues in low-lying and urban areas. The primary area that will be impacted by these is the Southern Plateau, Southern Tennessee Valley, and East Tennessee Mountains. However, gusty winds will be felt well northeast into the Central Valley and the Knoxville Metro as well.

(credit: NWS Spokane, Washington)1/22/2017 DISCUSSION: As a weak low pressure system gradually pushes through portions of central-to-northern California, a decent amount of moisture will continue to track eastward across portions of central-to-eastern Washington state. As this moisture moves across some of the higher elevated regions with the aforementioned parts of Washington, there will an increased likelihood of light "advisory-level" snowfall totals across this part of the nation during the day on Sunday. Having said that, although this will be a more minor snowfall event at best, it is still best to remain off the roads during the time in which the snowfall is falling at its heaviest. Thus, eliminating the largest threat for spin-outs, accidents, etc.

DISCUSSION: As a weak low pressure system passed through parts of northern New York state during the overnight period going from Tuesday night into Wednesday morning. As a mixed bag of precipitation continued from the afternoon hours and on into the evening hours of Tuesday, much precipitation across areas in and around the Capital District region of New York State quickly transitioned to freezing rain. This transition from rain to freezing rain was the result of cold air quickly surging into this region very close to and at the surface. This allowed the surface temperatures to cool substantially; while there was still a definite presence of warmer air (i.e., air temperatures marginally above the freezing mark in the low to mid-levels of the atmosphere. As a result, precipitation falling through the lower to middle parts of atmosphere over this region consequently melted and then re-froze as it reached the surface. This dangerous atmospheric precipitation regime facilitated the generation of classic icing event in several cities in and around the Capital District of New York. The collection of images attached above were courtesy of Connie Bradt, Jill Gulick, Karen Culligan, Toby Fraleigh, David Krzemien, and Lori. G. So, thank you to those local residents for their pictures and for CBS6 Meteorologist Craig Adams for sharing them with the meteorological community.
As always, with this recent icing event comes the typical issues tied to an icing event in any location around the world. As the ice accumulated on critical surfaces including (but certainly not limited to) highways, residential primary and secondary roadways, airport runways, commercial railways, etc. this creates travel delays, cancellations, and sometimes even accidents. Therefore, when a forecast for an ice storm event of any kind is bearing down on you, always make the best possible choice and avoid traveling at all costs. Remember, when you traveling by way of any conventional method of transportation and you are dealing with accumulating ice, it is essentially like "rolling the dice."

The two games on tap for today are The Pittsburgh Steelers at the Kansas City Chiefs and the Green Bay Packers at the Dallas Cowboys.
For those attending the Packers-Cowboys game in Arlington, Texas, a fog advisory was in effect for areas just to the south of Arlington, so those tailgating or arriving early to the game may have encountered some fog. A Dense Fog advisory was in effect until 3 P.M C.S.T today, so it should lift by kick-off. The current temperatures range from the lower-to-middle 50’s across the Arlington metro area. After the fog lifts, fans can expect overcast skies throughout the game with showers and thunderstorms possible through the late afternoon/early evening. While these storms may not occur during the game, they could affect those driving home. The Pittsburgh-Kansas City game was moved back to 7:20 P.M C.S.T. due to an ice storm impacting the Midwest, including Missouri (as reflected by the recent regional radar screenshot courtesy of Weathertap). Freezing rain affects travel conditions by making nearly all surfaces (e.g., highways, airport runways, etc.) slippery; thereby increasing the statistical likelihood of accidents. Currently, Kansas City, Missouri is reporting temperatures in the lower 30’s (which is right around the freezing mark) as they continue to experience light freezing rain/mist. Freezing rain is forecast to continue this afternoon before transitioning to rain later. This warmer air combined with the onset of rainfall will help to melt away a good portion of the ice which has accumulated throughout this latest winter storm. Tonight, there is another chance for freezing rain before gradually transitioning to rain in the late evening hours. The roads could still be icy tonight after the game. Although, due to the incoming rainfall, the roads will likely remain slick, so those driving should exercise extreme caution.

(credit: AMS Amarillo, Texas)1/15/2017 DISCUSSION: As the latest winter storm continues to rage on across many parts of the central and south-central United States, hundreds of thousands of people have already experienced the natural power and the brute force of this ongoing/long-duration ice storm. As you can clearly see for yourself in the image attached above (as shared by the National Weather Service office located in Amarillo, Texas), many trees such as this one (located just outside of the NWS Amarillo office) have been weighted down tremendously by the weight of the ice glaze which has enveloped much of the foliage across these parts of the nation. The bright light in all of this is that as the center of the associated low pressure system gradually lifts off to the north with time, warmer air which is currently situated much further south will also lift north. As this warmer air moves northward with time, the associated water vapor overhead will be released as rainfall. Therefore, this will help to substantially melt away much of the current freezing rain accumulated across many parts of the central and south-central states.
Nonetheless, travel (both by foot and/or automobile) continues to remain very hazardous across these areas and it has been strongly recommended to avoid and or all travel through or near these areas so as to avoid putting yourself in harms way. Remember, as with many ice storm events, venturing out just steps away from home can potentially become life-threatening due to falling and/or downed power lines. In addition, you also can run the risk of encountering falling tree limbs unexpectedly due to them giving way to the natural weight and pressure imposed by the associated ice accumulation. The message behind all of this is stay home as much as possible until it is communicated to you that it is sufficiently safe to go out and about.

This increasing winter storm threat will a result of the current low pressure system which is delivering a complex winter blast to the central/south-central United States. The majority of the current impacts which include (but are not limited to) snow, some sleet, freezing rain, and rain will be moving into the north-central United States over the next couple of days as this low pressure system gradually lifts northward with time. As you can denote from the graphic above (courtesy of the National Weather Service office located in North Platte, Nebraska, the evolution of this upcoming winter storm for this part of the country will be an array of freezing rain, snow, and then tapering off gradually by early/mid Monday afternoon as this incoming low pressure system pulls out of the north-central United States. As always, when the weather goes down-hill, avoid travelling as much as you can!

(credit: NWS Kansas City/Pleasant Hill, Missouri)1/13/2017 DISCUSSION: As the incredibly hyped ice storm began its attack on parts of Missouri as well as areas to the south and west of the "Show Me State," things began getting fairly dicey relatively quickly. As shown in the middle image (attached above) courtesy of the National Weather Service office located in Kansas City/Pleasant Hill, Missouri, there has been a notable amount of ice accumulation on many different surfaces across parts of far western Missouri. In addition, as reflected by the respective purple and light blue shading of the major highways across western and southwestern Missouri (in the lower image courtesy of the Missouri Department of Transportation (MoDOT)), many roads have already become or are quickly becoming increasingly more dangerous to travel along due to the increasing thickness of the regional ice accumulation. This image is current as of the regional Missouri
It is worth noting (in the reference to the last point made above) that the purple shading indicates roadways which are incredibly dangerous to nearly impassible for motor-vehicles of any type. Those roadways which are highlighted in a darker blue color indicate road conditions which are marginal but are becoming increasingly more dangerous with time. Therefore, it is clear from the image attached in the slideshow above that the overall state-wide road conditions across the state of Missouri are becoming increasingly hazardous with time. If you do not need to absolutely be out and about over the next 24 to 48 hours, do not travel to maximize your personal safety.

(credit: NWS Kansas City, Missouri)1/12/2017 DISCUSSION: As noted across multiple social media sources from across the Central and South-Central United States, there is a very ominous winter storm threat bearing down on these parts of the country. As noted in the upper graphic (attached above), the worst hist areas within the NWS Kansas City/Pleasant Hill forecast region will likely be approximately from central/eastern Kansas to eastern Missouri. The worst impacts are expected to be in and around areas positioned along and to the south of Interstate-70. Therefore, if you have family or friends in the midst of a cross-country trip or potentially who live in these areas, be sure to advise them of the dramatically increased hazards with attempting to drive through this icing event. Attached below is a piece taken from the upper graphic:
"Remember all those winter weather awareness posts we've made the last several weeks? Well, now it's time to put it all to practice. An Ice Storm Warning has been issued for the entire area, and we could see up to 1/2" to 3/4" of ice through Sunday night. There could be disruptions with transportation and power infrastructure throughout the weekend and into early next week. NOTE: While the graphic says up to an inch, any amounts that high would be very isolated. In general we expect areas in red to see 1/2" up to 3/4"." In the lower graphic (also courtesy of forecasters at the National Weather Service office located in NWS Kansas City/Pleasant Hill), you will note how they break down the anticipated conditions in the respect colo-coded zones based on the magnitude of the icing which is forecast to occur at this time. Attached below is a piece taken from the exact post from their office as of a little earlier this evening as it pertains to the above impact post: "Here are our expected start times for ice tomorrow as well as anticipated impacts. This is through Friday night only. Conditions will worsen further north later in the weekend. CORRECTION: The Zone 1 wording should read most "EARLY" PM travel ok.

(credit: NWS Pueblo, Colorado)1/12/2017
DISCUSSION: As yet another eastern Pacific low pressure system begins to come ashore, there will be yet another onslaught on heavy elevated snowfall as well as strong winds further inland. This incoming storm system will be delivering a variety of impacts to the region which will be a major threat to many people's and organization's life and property. Attached below is a verbatim exerpt from forecasters at the National Weather Service office in Pueblo, Colorado about this upcoming winter storm which will take hold of a good portion of the Plains states over the next 24 to 48 hours. As noted in the text below, there will be a large region being threatened by impacts from freezing rain which will make for incredibly hazardous travel of all forms so avoid travel through parts of Illinois, Missouri, Iowa, Arkansas, Kansas, and more.
"Latest GOES Water Vapor Imagery and forecast track of system expected to bring widespread precip to Colorado through the weekend. The Continental Divide will see accumulating snowfall through early Tuesday. The greatest chance for precip across the Plains will come Saturday into Sunday.

(credit: NWS Reno, Nevada)1/11/2017 DISCUSSION: As noted in an earlier post yesterday evening by Meteorologist Jesse Olsen, there is a continued threat for heavy snowfall in the more elevated parts of California and Nevada. Attached below is some text included verbatim from the corresponding Facebook post associated with this continued elevated winter storm threat for these areas.
"A Blizzard Warning has been issued for the Sierra through Wednesday morning. Dangerous and potentially life threatening blizzard conditions are possible in the Sierra. See latest statement: http://go.usa.gov/x9QDg Multiple feet of snowfall are expected. Strong winds will produce zero visibility in whiteout conditions along with high drifting snow. Do not attempt to travel as first responders may not be able to rescue you. Travel may already be impossible with several road closures due to heavy snow already being reported. Even a short walk could be deadly if you become disoriented. Avalanche danger will remain high through this storm. Stay home, stay safe!"

(credit: NWS Springfield, Missouri)1/11/2017 DISCUSSION: As a weak low pressure system begins to develop along a nearly stationary frontal boundary, there will be an increasingly more favorable set-up in place for a freezing rain threat. This increasing freezing rain threat will be directly attirbuted to colder (and denser) air being pumped into the region undercutting warmer (and more buoyant) air being pumped into the region from the south. Thus, this will be creating an overrunning situation wherein hydrometeors (i.e., rainfall) falling through the warmer mid-level layer(s) melt the precipitation before it then falls through the colder layer close to (or possibly right at) the surface. Hence, this will likely make for a very treacherous Friday and Saturday as far as regional and national (ground and air) travel in concerned. Therefore, if you have a need to travel through this part of the United States over the next couple days as we approach the weekend timeframe, be sure to try to accomplish as possible so you will not be in a rush duringe the more treacherous travel conditions.

DISCUSSION: As heavy rainfall continued to persist throughout the day across many parts of California, many areas experienced severe flooding and even flash flooding in many cases. As reflected by the footage above which was captured earlier today (courtesy of Ivan Natividad and TheUnion) over in Nevada City, California, some floodwaters became incredibly dangerous as they engulfed entire communities in raging "white water" rivers. This was caused by persistent torrential downpours over the same areas for a relatively long period of time. Furthermore, this was then worsened by the natural rainfall water run-off which was induced by the positioning of valleys and ridges in and around both Nevada City, California and many other cities across the state of California as well for that matter. Unfortunately, these sort of floodwaters are expected to persist as torrential downpours continue for at least the 24 to 48 hours in many places across central-to-northern California.

DISCUSSION: Winter storms can have numerous direct and indirect impacts on communities. For example, winter weather can directly make travel more difficult and dangerous. This, in turn, can make getting to an event such as a basketball game unecessarily risky. Thus, the scheduled basketball game between the University of North Carolina (UNC) and North Carolina State originally sceduled for last night (1/7/2017) was rescheduled for today (1/8/2016; an indirect impact of the winter storm). As can be seen in the above graphic, the Chapel Hill area (near Durham) received ~3-5 inches of snow/sleet as of last night in an area that only receives about 4 inches of snow on average per year. Thus, central North Carolina may not be as used to dealing with this type of weather as other areas which have to deal with it on a more regular basis. This probably played a role in UNC's decision to err on the side of caution and postpone the game. This provides a good lesson for everyone, especially in communities not used to this type of weather - Be very careful if you must travel or go out in a winter storm, and if at all possible try to avoid the risk and stay in. This is especially relevant to states along the West Coast over the next several days as a series of storms impact the region.

(credit: NWS Jacksonville, Florida)1/6/2017 DISCUSSION: As discussed in more detail within the previous post on this upcoming winter storm, this is a multi-faceted winter storm with many different aspects. Although the primary focus has been and will likely continue to be the more wintry aspects of this strengthening low pressure system, there will also be a marginal severe weather threat in place across portions of northern-to-central Florida. This lower-end severe weather threat will primarily be the result of strong warm air advection occurring alongside and just to the east of the associated cold front which will be pushing through the region during the day tomorrow. Thus, the primary threat from any deeper convection which develops during the day tomorrow out ahead of and/or right alongside the incoming cold front will be an increased threat for heavy rainfall, strong straight-line winds, and frequent cloud-to-ground lightning.
Attached below is some exact content issued by forecasters at the National Weather Service office in Jacksonville, Florida: "Heavy downpours and embedded strong thunderstorms are possible this evening in the Suwannee Valley of northeast Florida and through the overnight hours across the rest of northeast Florida. The Storm Prediction Center has indicated a marginal risk for severe thunderstorm development along the I-75 corridor tonight. Stronger activity will be capable of producing small hail, wind gusts up to 50 mph, and frequent cloud to ground lightning strikes. Activity is moving quickly northeastward at nearly 40 mph. Rainfall amounts near 1 inch are expected, with locally heavier amounts possible through the morning hours on Saturday."

(credit: NWS New York, New York)1/6/2017 DISCUSSION: As a weak low pressure system begins its gradual process of intensification as it transitions from its current position in the northeastern Gulf of Mexico and on towards the East Coast of the United States, the national headlines will quickly be changing. As shown the lower graphic (attached above and courtesy of the NWS Storm Prediction Center located in Norman, Oklahoma), there is a plethora of precipitation breaking out to the north and east of the developing surface low which will soon begin to slowly emerge from the northeastern Gulf of Mexico. Based on the evidence provided by the middle graphic (courtesy of www.weathertap.com), you can see the mix of precipitation types dispersed throughout this developing low pressure system. More specifically, there is more frozen precipitation (i.e., snow, sleet, and/or freezing rain) on the northern side of this strengthening winter storm. However, on the southern side of this developing low pressure system the warmer air is having a more dominant influence and is thereby generating more rainfall.
It is worth noting that based the early position of this particular winter storm's low pressure center in the northeastern Gulf of Mexico, this horizontally-distanced change in precipitation type is not that unusual as far as weather history is concerned. This is chiefly due to the fact that during the earlier part of developing Winter-time low pressure system's life-cycles, you often find very strong warm air advection processes dominating on the southern half of the system or further which is a critical aspect of some of the more impressive winter storms throughout the all-time record books since this strong southerly flow provides the critical warm air advection which bolsters the potential for heavier snowfall accumulations during a given winter storm. Since this winter storm is expected to track somewhat close to the classic coastal winter storm track, National Weather Service offices along much of the East Coast are very much "under the gun" with e-mails, conference calls, media hits, and typical forecasting responsibilities as they get deeper into "winter storm mode." One of jmany NWS offices in hte path of this impending wointer storm includes (but is not limited to) the National Weather Service office located in Upton, New York. As you will note from the upper-most graphic (courtesy of NWS Upton, NY), there is currently a high confidence forecast in place for accumulating snowfall across much of Long Island and beyond there as well! As also noted in the upper-most graphic (attached above), the worst impacts will be felt my many people across the NYC metro area and points to the east during the day on Saturday (01/07/2017) and will not conclude until after sunset tomorrow evening.

(credit: NWS Denver/Boulder, Colorado)1/6/2017 DISCUSSION: Ever wonder it is like to visualize an entire state covered in snowfall from north to south and from west to east? Then wonder no longer because Colorado is one of the few states from across the lower 48 contiguous United States of America which currently has nearly the entire state covered in snowfall as depicted in the visible satellite image captured much earlier this morning (6 January 2017). It is worth noting that this is not climatologically uncommon for this part of the country due to the higher prevalence of large amounts of snowfall during the period from late October/early November through early April across the Front Range of the Rocky Mountains, throughout Rocky Mountain National State, and beyond. Having said that, in the wake of several strengthening low pressure systems which have moved through the state of Colorado in recewnt days and weeks, it is still impressive nonetheless to see this tremendous extent of overall state-wide snowfall cover.

DISCUSSION: As the strong lake effect snow band began to slowly move ashore into many parts of western New York (i.e., many cities positioned along the eastern shore of Lake Erie), many motorists found themselves in a very treacherous situation. As the heart of this intense lake effect snow band continued slowly shifting further inland, snowfall accumulated particularly quickly on the roads and also rapidly brought down local visibilities to near zero at many times. As seen in the picture above (courtesy of WeatherNation), the snowfall was indeed quite heavy with very slow travel being the only option during the periods of heaviest snowfall as the lake effect snow band continued to be pushed inland. This shifted position from the band being positioned over the heart of Lake Erie and over towards eastern shoreline and beyond was the result of winds which were previously out of the southwest beginning to shift to being more out of the west-southwest and eventually due west. Hence, this limited the total distance over which the colder air was able to travel and weakened the overall lake effect response off of Lake Erie and pushed the primary lake effect towards the eastern shoreline and beyond with time.

(credit: NWS Buffalo, New York)1/4/2017 DISCUSSION: As of earlier today, a major lake effect snowfall event began to get underway off of both Lake Erie and Lake Ontario. As of late tonight, very intense long-lake axis parallel (LLAP) bands have formed and maintained themselves east of both Lake Erie and Lake Ontario. As noted in the graphic above, prolific snowfall totals are expected east of these respective lakes and the event will likely not end until near 12:00 PM EST or later on Friday (January 6). More specifically, areas positioned just to the east of Dunkirk, New York may receive upwards of 2 to 2.5 feet or more of new snowfall. In addition, areas positioned to the east of Sandy Creek, New York and just west of Lowville, New York could quite possibly receive upwards of 2.5 to 3 feet or more of new snowfall. It is imperative to note that as this event continues to ramp up overnight, conditions will become treacherous to near impassible at times along many county and state highways. Therefore, if you need to move out and about over the next 24 to 60 hours, be sure to leave plenty of extra time.
