A strong front is still expected to usher in a surge of arctic air tomorrow into Tuesday.
There have been no changes with timing of the front; it will pass through east Texas tomorrow afternoon, Louisiana, Mississippi, and north Alabama tomorrow night, the rest of Alabama and the Florida Panhandle Tuesday morning, and the peninsula of Florida later Tuesday/Tuesday night.
Showers/storms continue to be expected along/ahead of the front.
While previously thought to be unlikely, a brief change over to a mix of some sleet and flurries across north/central Mississippi and Alabama, roughly along/north of a line from Natchez/Hattiesburg, MS to Anniston, AL is looking possible Monday night/early Tuesday.
Some sleet pellets mixing in with rain is looking like a possibility across parts of central and southeast Texas Monday night/Tuesday morning, too (see figure 2).
However, if there were to be any frozen precipitation, there would likely be little if any accumulation/impact.
Temperatures will drop rapidly (likely by 15 to 25 degrees) in the wake of the front. A strong north wind with gusts in the 25 – 35 mph range will make it feel even colder.
The coldest temperatures are still expected to occur Tuesday night into Wednesday, when the freezing line will make it down to central Gulf Coast (see figure 1).
