DISCUSSION: As the low pressure system which has remained nearly stationary for the past couple of days finally begins to slowly head off to the east over next 24 to 48 hours, much more heavy rainfall will come to many other states in and around the Mississippi and Tennessee Valleys. As shown in the animated satellite imagery attached above (courtesy of the Cooperative Institute for Meteorological Satellite Studies or CIMSS), this latest low pressure system impacted many parts of the central United States with heavy rainfall and heavy rainfall from west to east across the storm. As you can also see from the animated water vapor imagery attached above, you can also see how there a clear moisture track connection which tracked up and into the central United States from the Gulf of Mexico. Hence, the strong tropical connection originating from the Gulf of Mexico helped to facilitate the persistent, long-lived heavy rainfall event which has severely impacted states including (but not limited to) Missouri, Oklahoma, and Arkansas.

DISCUSSION: Over the past couple of days, a potent low pressure system developed along the East Coast of the United States. As this system went on to deliver a plethora of rainfall to many states across the Mid-Atlantic and the Northeast, there were also some very neat perspectives gained which were courtesy of the incoming data stream from GOES-16 (or more commonly being referred to as GOES-R). Attached above is a neat animation of the three primary water vapor channels which are available aboard the GOES-16 satellite platform. Notice how within the three respective water vapor channels, you have the ability to visualize different aspects of the atmosphere (e.g., with respect to air stream flow as well as the variable chemical composition of the atmosphere). Thus, there is no debate whatsoever that the onset of the GOES-16 era is going to quickly bring about a rapid increase in the amount of data and the tremendous insights which will be gained from all of this state-of-the-art data.

A Closer Look at The Tops of Thunderstorms From Recent Louisiana Storms! (credit: UW-CIMSS)4/4/2017 
DISCUSSION: In light of the recent severe weather event which impacted portions of the South-Central United States, there were many neat and insightful perspectives taken on this severe weather outbreak. As shown in the animated higher-resolution satellite imagery attached above, there was a very complex evolution of these storms with respect to cloud-top temperatures. This was a definite indication of rapid storm development and subsequent in-situ updraft evolution as they continue to push off to the northeast with time. This animation compares GOES-16 (non-operational) 1 minute, 2 km IR imagery side-by-side with GOES-13 (operational) 15 minute, 4 km IR imagery of the April 2nd tornadic thunderstorms in Louisiana.
As storms continued to evolve in character from the point at which they developed closer to the Gulf Coast region, the deep-layer rotation increased substantial which boosted the overall threat for rotating updrafts within intensifying storms. This consequently increased the threat for tornadogenesis in association with several strong discrete storms which formed during the course of the late morning to late afternoon hours on Sunday.
