DISCUSSION: As a weak low-pressure system slowly moves off to the west across several islands within the South Pacific Ocean, there will be a rather complex convective forecast unfolding with scattered, discrete convective storms being the main theme. As a result of the weak low-pressure system dragging warm/moist air into the region, there will be greatly enhanced buoyancy in place which will aid in the development of typical deep tropical convection. As seen in the graphic below courtesy of the National Weather Service office in Barrigada, Guam there is no question that this forecast is littered with complications based on the number of factors which will have an influence on how the forecast for the next few days unfold!

DISCUSSION: As strong thunderstorm rapidly increased in intensity earlier today, a few of the storms which moved across parts of Central to Eastern Singapore became particularly intense and produced a plethora of lightning! For example, here is a great perspective of one thunderstorm which was found to be particularly photogenic between a clear capping inversion at the top of the storm which prevented the updrafts from ascending any further.

DISCUSSION: As of earlier this morning, very deep convection was firing just east of Eastern India which has already produced tremendous amounts of rainfall across the Subcontinent region. That being said, as this previously discussed tropical low-pressure system continues sliding slowly off to the north, the threat for heavy rainfall and associated flash flooding will persist for another few days moving forward. In addition, there will be a corresponding threat for mudslides and/or landslides as the topsoil on mountain/hillsides continues to become less stable due to all of the excessive rainfall occurring over the last 48 to 72 hours! Note how in the short satellite imagery animation below how you can identify the areas of deeper convection based on the locations of the more "bubbly" appearance of the cloud structure close to the center of the animation and even a few surrounding areas near the end of the loop!

DISCUSSION: As a weak tropical low-pressure system continues to slowly move northward as it remains positioned just offshore from Southern India and Eastern Sri Lanka, the largest heavy rainfall threat will continue to shift northward over the next 24 to 48 hours. As seen in the latest regional forecast data trends, this tropical low-pressure system will likely continue to slowly ride up the Eastern Indian coastline; producing heavy/persistent rainfall for 48 to 72 hours across a good portion of the subcontinent region! This will likely prime many regions within India and Bangladesh for flash flooding and subsequently life-threatening mudslides and landslides.

DISCUSSION: As a weak tropical low-pressure system continues to slowly move to the north just offshore from Southern India and Eastern Sri Lanka, the rainfall threat will be shifting northward over the next few days. Note (as seen in the attached graphic below courtesy of tropicaltidbits.com via Levi Cowan) how the low-pressure is expected to slowly ride up the Eastern Indian coastline; producing heavy/persistent rainfall for 48 to 72 hours across much of the subcontinent region! This may also set the stage for destructive flash flooding and life-threatening mudslides and landslides. For more neat high-impact weather content from across Asia, be sure to click here!
DISCUSSION: As multiple low-pressure systems made their way across Eastern Asia and out over the waters of the North Pacific Ocean over the last 7 to 10 days, a plethora of intense atmospheric water vapor transport has unfolded. As you can see in the short animation attached below (courtesy of the Earth Facebook venue), the aforementioned low-pressure systems acted to vigorously transport tons of warm/moist air all the way from the tropical/subtropical regions of the Central and Western Pacific Ocean towards the Southern periphery of the North Polar regions to the north of Alaska over the course of several days!

DISCUSSION: In looking towards the Western Pacific Ocean just a few days ago, there was clear evidence on visible satellite imagery of a strengthening extratropical low-pressure system moving passed the island of Japan with rain and snow impacting the lower and high elevations respectively throughout many parts of the country. Note how you can clearly identify the classic occluded "comma-head" structure of this maturing low as it quickly moves away from Japan in a northerly to northeasterly direction over the past 48 hours! It is always awesome to see textbook atmospheric cyclone wrap-up structure as originally defined by the Norwegian Cyclone Model schematic back in the early 20th Century by Vilhelm Bjerknes!

AN UNUSUAL PRESENCE OF A HAIL OBSERVED YESTERDAY AFTERNOON IN SAUDI ARABIA! (credit: Youssouf Ali Al Taher via Cyclone of Rhodes)
DISCUSSION: Much earlier yesterday afternoon, a weak low-pressure system moved east of the Mediterranean Sea and headed towards Western Saudi Arabia. As deep convection flared up across parts of the Middle East earlier yesterday, a few isolated storms such as this one observed over Eastern Saudi Arabia generated impressive amounts of hail! See the video below to see just the density of hail falling at the time!
