Heavy, drenching thunderstorms will be possible in the lower Mississippi Valley into Tuesday night as a cool front slices eastward.
As the surging warmth spreads throughout much of the East, this mild and moist air will help produce wet weather from the Great Lakes southward into the western Gulf Coast as it interacts with the frontal boundary.
Areas from Kentucky and Tennessee into Arkansas and eastern Texas have the best chance for thunderstorms.
Located along the cold front passing through the region, these showers and thunderstorms will progress eastward throughout the course of the day. The best chance for thunderstorms will come during the afternoon and evening hours.
Although there is not a heightened risk for strong-to-severe thunderstorms, a few of the storms could briefly approach severe limits.
Storms will have the capability of producing brief blinding downpours. Motorists should be advised to slow down if they are to encounter such storms.
The heavy rainfall will be welcome by those who are currently in a slight to moderate drought; notably, eastern Texas and western Louisiana.
In addition to the heavy downpours, the strongest storms may be capable of producing wind gusts between 30-40 mph at times. With cold air aloft, a marginal threat for small hail exists as well.
Residents in the corridor from the Gulf Coast of Texas northeastward into Louisiana, southern Arkansas and western Mississippi will have the best opportunity of seeing strong-to-severe storms.
This includes the cities of Jackson, Miss., and Houston, Texas, as well as Shreveport and Alexandria, La.
As the storms continue to march eastward on Tuesday night into Wednesday, somewhat cooler air will move in behind the front. The frontal boundary is relatively weak by December standards and temperatures will still remain above normal on Wednesday.
Temperatures will warm up once again starting on Thursday thanks to a southerly breeze. The mild air will stick around through the weekend.
