Severe Weather, Tornadoes and Flooding Continue...

Soggy Sunday
Jon Howard snapped this picture from the Elm Creek Park Reserve on Sunday, he said the trails were swamped. 


Precipitation Past 7 Days
Radar estimated rainfall over the past 7 days suggests that widespread 1" to 2" of rain has come down along the I-94 corridor, with more precipitation to come.


Sunday's HIGH RISK
The HIGH RISK on Sunday was one of the highest severe risks of the season thus far.


Stormy Sunday
Thanks to @Ryan_Graves33 for this tornado picture near Galena, KS on Sunday


Satellite Sunday
The satellite on Sunday looked quite impressive along a dryline that was setup on the KS and MO border. Thunderstorms at this point were tornado warned 


Radar Sunday
This is what the radar looked like on Sunday as the storms were erupting across the Plains


Impressive Tornado on Radar Near Little Rock
Here was one of the tornadoes via radar on Sunday evening just NW of downtown Little Rock, AR!! In fact, the tornado warning that was in effect for this particular storm was a TORNADO EMERGENCY... this is what the tornado emergency text looked like!


Severe Threat Continues
Look at how slow the storm system is... the loop below from AM Monday to PM Tuesday, the center of circulation moves east about one state; from Nebraska to Iowa. The waterlogged storm system will still be kicking out heavy rain and severe weather through the middle part of the week.


Severe Threat Monday
...LOWER MS VALLEY EWD INTO NRN AL AND MIDDLE TN... WHILE THE PREVIOUS DAYS CONVECTION WILL LIKELY PLAY A ROLE IN DELINEATING THE PRECISE THREAT CORRIDOR...A SW-NE ORIENTED ZONE OF TRAINING SEVERE THUNDERSTORMS IS LIKELY FROM NERN LA ACROSS MS AND INTO NRN AL AND MIDDLE TN. THE STORMS WILL EITHER BE TIED TO THE COLD FRONT...OR AN OUTFLOW BOUNDARY WHICH COULD SPREAD OUT AHEAD OF THE MAIN SLOW MOVING FRONT. REGARDLESS...A VERY MOIST AND UNSTABLE AIR MASS WILL RESIDE AHEAD OF THE COLD FRONT...WITH SHEAR PROFILES QUITE FAVORABLE FOR SUPERCELLS AND TORNADOES. A LONG UPDRAFT RESIDENCE TIME IN THE UNSTABLE AND HIGHLY SHEARED ENVIRONMENT...AS WELL AS RELATIVELY STEEP MIDLEVEL LAPSE RATES SUGGEST STRONG TORNADOES WILL BE POSSIBLE. VERY LARGE HAIL WILL ALSO OCCUR AS WELL AS POTENTIAL FLOODING. THE MOST SIGNIFICANT TORNADO THREAT IS EXPECTED ACROSS MS.


Severe Threat Tuesday


Severe Threat Wednesday


Slow Moving Storm Continues
Here's another view of the storm as it slowly moves east. The loop shows the storm from PM Sunday to AM Thursday. Note that there isn't much movement from west to east. Also, the moisture conveyor belt continues to send moisture north/northwest through this entire time!


5 day Precipitation
According to NOAA's HPC, the 5 day precipitation forecast suggests quite a bit of precipitation yet over the eastern half of the country along with the Midwest. It's a waterlogged storm that doesn't seem to want to quit. Flooding is going to be a real Likelihood with as much rain as some could see through the end of the week. 


Flood Concerns
* FROM MONDAY EVENING THROUGH WEDNESDAY MORNING * RAINFALL AMOUNTS OF NEAR 4 INCHES WITH LOCALLY UP TO 6 INCHES ARE POSSIBLE ACROSS PARTS OF THE CENTRAL AND SOUTHERN TENNESSEE VALLEY AND PLATEAU
