As the squall line marches east across the state, it should begin to lose alot of stream and break apart for the eastern portion. I showed the approximate time frame for all of this last night and it looks like areas west of I-55 will see the storms arrive sometime between midnight and 6am Wednesday; east of I-55 will see the storms from 6am-Noon Wednesday. The worst of the weather should be over by afternoon.
Temperatures behind this cold front won't be cold, as this is a Pacific cold front. Our temperatures will remain in the 60s & 70s for the rest of the week. Another cold front arrives Friday with more thunderstorms.
Here is the latest graphic from the NWS. Before you go to bed tonight, make sure you have your weather radio on. By the way, WLBT is programming the Midland Weather Radios at various Walgreens across the area for the rest of the week from 3pm-6pm. Today, we'll be at the Walgreens in Flowood.
