April 30: Daytime Thunderstorm Forecast

The image above is for around 4:00 pm CDT. We do see some storms beginning to develop in the Southeast Arkansas/North Louisiana area around this time as a strong low pressure in Canada with a trailing cold front works its way across the South US. There will also be some isolated storms in South Florida.
This cold front will cross the entire US, pretty much for everyone east of the Mississippi River.
However, with a more ample supply of humid air down south, there is a slight risk of severe storms. A tornado outbreak is not expected. Below is the slight risk area.

The slight risk extends through the following areas:
-Extreme South IL
-Extreme West KY
-Extreme Southeast MO
-Much of Arkansas
-Extreme West TN
-Extreme Northwest MS
-Portions of North TX
-Extreme Southeast OK

There will also be a threat for plain thunderstorms in green, but again, the supply of humid air will keep south, thus the slight risk.

This is an image of the probability of thunderstorms for 6:00 pm CDT today. We see a much more defined area of potential storms in Arkansas, where the highest percentage threat of REGULAR thunderstorms is up to 95%.
By the way, I don't know why this map has percentages over 100. I didn't make the map, so unfortunately I can't answer that.
Thunderstorms will be somewhat of an isolated nuisance in Southern Florida while way offshore there will be storms.
Check back tonight for tonight's thunderstorm forecast.
