Cooler Temps Today, Southeast Severe Threat

Heavy Weekend Rain
The Upper Midwest picked up some impressive precipitation totals, here is a look at the radar estimates from across the region thanks to the NWS
The upper midwest received multiple rounds of rain and some snow over the weekend.  The rainfall was much needed to help combat the ongoing drought conditions across the region.  Below is a summary of how much precipitation was received over this past weekend.
Below is the 72 hour (7AM Friday through 7AM Monday) accumulated precipiation estimate from radar.
As you can see, much of southern Minnesota  and west central Wisconsin received 1.5 to 3.0 inches of precipitation from Friday to Monday.
Here is a link to the Regional Max/Min Temp and Precipitation Table which shows the 24 hour precipitation totals as of this morning.  You can select previous versions of the table to see 24 hour precipitation totals from previous days.

Weather For Dummies by Josh Johnson
It’s happened for years now – the national (and some local) media just can’t seem to report weather-related stories without goofing something up. There are times where the goofs are minor, but many of the mistakes are substantial. It’s even worse that this is happening at the national network level, where, in theory, the reporters and anchors should be “the best of the best.”
Heavy Texas Rain
Thanks to Cindy Morgan for this picture from Texas. At the time of this picture, she had nearly 8″ of rain and as she put it… Lake Morgan developed in the backyard.
Flooding in Texas
Thanks to the National Weather Service out of Corpus Christi, TX for the picture below from Gregory, TX
Incredible Radar Rain Estimates
A cold front stalled across the Coastal Bend Monday.  At the same time, an upper level disturbance is moving into the region.  With the stalled cold front boundary, training of thunderstorms across the same areas allowing local pockets of 3 to 5 inches causing localized flooding. The most prolific rainfall that occurred Monday occurred east of highway 77 along the Coastal Bend, where 12 to 16 inches occurred in the Portland-Gregory region extending northeast just south of Bayside and west of Rockport.  Another pocket of 8 to 10 inches has occurred Northeast of Refugio, and another 6 to 8 inches between Quintana and McFaddin. Remember when encountering a flooded roadway or overrunning creek, Turn Around, Don’t Drown.  Some areas received 1 to 2 inches of rain per hour…mainly east of Highway 77.
Severe Threat Today
The Storm Prediction Center has highlighted parts of the SE under a SLIGHT RISK of severe weather. Hail and high winds looks to be the primary threat.
