This disturbance is riding along a stationary boundary draped from central Arkansas, through north-central Mississippi, over into Alabama. Tomorrow, that stationary boundary will begin a slow southward migration as a cool front. This will be the focus for more scattered thunderstorms, especially in the afternoon.
The latest model data shows thunderstorm activity beginning along the I-20 corridor shortly after noon:
By 5PM, the stationary boundary will have moved closer to HWY 84, and the best chance for thunderstorms will be from Natchez to Brookhaven to Hattiesburg:
Keep in mind that any storms that do form could quickly become severe and contain straight-line, damaging wind gusts in excess of 60-70mph--strong enough to bring down trees and power lines--as well as vivid lightning and small hail. Locations that see the strongest storms could pick up a quick 1" of rain as well.
Once this front shifts to our south tomorrow afternoon, we'll enjoy a quick shot of less humid air for a day or so, however, temperatures will remain near 90.
A more typical June-like patter returns by the weekend--highs in the low 90s, with slight chances for isolated afternoon thunderstorms each and every day.
Enjoy the rest of your week!
