There will be a threat for severe weather for East Texas, all of Louisiana and Mississippi, and portions of Alabama and Florida Panhandle tomorrow afternoon into early Wednesday.
Storms will develop along a cold front over East Texas around noon tomorrow and evolve into a squall line tomorrow evening.
The squall will advance south and east overnight through Wednesday morning, across Louisiana and Mississippi, and into Alabama and the far Western Florida Panhandle (though latest guidance indicates it will have weakened substantially by the time it gets into Alabama and the Florida Panhandle).
Severe weather remains a possibility.
The Storm Prediction Center (SPC) still a “slight risk” for East Texas and much of Louisiana, and has expanded it to include most all of Mississippi (excluding Southeast Mississippi and Northwest Alabama (see figure 1).
The “marginal risk” area has also been expanded, and now includes areas of Alabama and the extreme Western Florida Panhandle (see figure 1).
The SPC has also outlined a “marginal risk” for the remainder of Alabama and Florida Panhandle for later in the day Wednesday. The overall severe weather threat will be much lower by then, though.
Straight-line winds and large hail still look to be the primary threats. However, all modes of severe weather (damaging winds, hail, tornadoes) will be possible, meaning a few weak, short lived spin-ups (tornadoes) can’t be ruled out.
Periods of heavy rain can also be expected, with rainfall amounts of 0.25″ – 1.25″.
