April 15 Severe Weather Outbreak

Once again, today we will be dealing with a severe weather outbreak.
The Storm Prediction Center has placed portions of the Southeast in a moderate risk for severe storms.
Below is today's overall risk.

As we can see, there is a moderate risk over the following areas:
-Much of Mississippi
-Much of Alabama

There is also a slight risk for severe weather over the following areas:
-Southern 2/3 of Illinois
-South Indiana
-Much of Kentucky
-Southeast Missouri
-Extreme East Arkansas
-Much of Tennessee
-Much of Georgia
-East half of Louisiana
-Florida Panhandle
-Western North Carolina
-Western South Carolina

Below is today's tornado risk.

It does appear that the threat for tornadoes prompted this moderate risk area to be issued.
That said, it can be expected at least a local tornado outbreak will occur.
Next is the threat for large hail.

There is an elevated risk in most of the moderate area up north, but the hail risk did not warrant the moderate risk area.
Next and last image is the high wind risk.

There is a 30% chance of damaging winds in the moderate risk area. However, 45% chance of damaging winds is needed for a moderate risk of severe weather.

In summary, a tornado outbreak is growing more concerning in the Southeast.
