Low Risk Severe Potential For April 23rd

A cold front will be making its way east wards across the country today (seems like we just did this about a week ago or less) and this cold front will serve as the trigger to possibly create some severe weather potential.

We have the day pretty much over all as a low risk day which is the equivalent of a see text from SPC.
Temperatures across the region are going to be mainly in the 60s and 70s .. In other words beautiful temperatures for this time of the year and nothing to "hot" .. temperatures behind the front look to fall back into the 50s.
CAPE looks to be quite meager with 500-1000. It should be noted that across this same region shown here the ECM is not showing any CAPE whatsoever ..

Lift index across the area is about -2 to about -4 . 
There is ample wind shear coming in with this cold front as it moves across the country..And EHI would NORMALLY support supercells across KY and TN.. 
However at this time frame there is not yet any moisture into those regions..
Total precipitation across Western TN and Western KY looks to be about a half into to three quarters of an inch of rain. With this being a low risk severe day we think any severe weather that does occur would be isolated and this would be gusty winds and hail in locations that do receive anything severe. Otherwise your main threats will be rainfall . 

A heavy rain event looks like it could be on tap for the southeast over the weekend. We will have more about this as the time gets closer!
