Temperatures rose to the low-80s Saturday afternoon, but a cold front moving in tonight brings a threat of a few severe storms.

The risk of severe storms comes AFTER 10 PM in North Alabama and Southern Middle Tennessee.

Severe storms are possible in Mississippi and West Tennessee between 6 PM and 9 PM, but from around 9 PM until 7 AM, we’ll be watching those storms in North Alabama and Southern Tennessee.

Our primary threats will be some gusty winds over 50 MPH and some hail; a tornado is possible. It’s just that time of year when we can see storms produce those kinds of things without a ‘major’ storm system rolling right overhead.

The Storm Prediction Center has upped the probability of tornadoes in Tennessee and Mississippi tonight. The 10% ‘hatched’ area means a 10% chance of a tornado within 25 miles of a point. You could look at it like this:

If the risk of a tornado on this given date according to climatology is 0.4%, this is a 250-times greater chance that a tornado could happen within 25 miles of you. It’s still not a very high number, but it speaks volumes about our confidence that tornadoes will happen within some storms tonight.

This line of storms weakens after 3 AM as it approaches Northeast Alabama and the Cumberland Plateau; that accounts for the sharp drop-off in the tornado probability level.
