Frigid, arctic air is on track to invade this week.
A strong trough is going to dig south tomorrow, and become established over the Central and Eastern portions of the country. This will cause two substantially colder air-masses to drop down into the country — the first doing so tomorrow.
Rain tomorrow and mid to late week:
Tomorrow: The cold front that will deliver the first colder air-mass will sweep east tomorrow. Unsettled, wet, and stormy weather will be likely from East Texas to the Western Florida Panhandle along and ahead of it. Severe storms are unlikely, however.
Mid to late week: A wet, unsettled pattern will continue persist through the end of the week across most of the North-Central Gulf Coast Region despite the frontal passage. This is because multiple waves (disturbances) will move through along the backside of the aforementioned trough.
Tomorrow – Friday:
Much colder air will filter in the wake of the front tomorrow.
Also, looking at the latest model guidance, it appears temperatures will drop lower than previously thought.
North-Central Gulf Coast: Tomorrow night/Wednesday morning lows will be anyhwere from the upper 30s to lower 50s. Wednesday night/Thursday morning, lows will range from the upper 30s to lower 40s overnight, and the mid 30s to around 40 overnight Thursday/Friday morning. Highs will generally be in the 50s from each day, with the exception of tomorrow, when many locations will get up into the 70s before the frontal passage.
East Texas and North-Central Louisiana, Mississippi, and Alabama: Highs tomorrow will peak in the upper 60s, and will occur in the morning, before the frontal passage.
Tomorrow night/Wednesday morning lows will be between the upper 30s to mid to upper 40s. Low temperatures will range from the lower mid 30s to around 40 Wednesday night/Thursday morning. Thursday night/Friday morning, lows in the the lower to upper 30s will be likely across North-Central Louisiana and East Texas, and in the mid 20s to lower 30s across North-Central Mississippi and Alabama.
On both Thursday and Friday, highs are expected to range from the upper 40s to mid to upper 50s.
This weekend into early next week:
A second front will push through Friday night and Saturday. The second air-mass will settle in behind it, kicking the wet weather out and dropping temperatures the lowest they have gone this season so far.
North-Central Gulf Coast: Lows will range from the lower to mid 30s Friday night/Saturday morning, the upper 20s to lower 30s Saturday night/Sunday morning, and the lower to mid 30s again Sunday night/Monday morning.
In regard to high temperatures, it appears they will range anywhere from the upper mid 50s to mid 60s on Saturday, Sunday, and Monday.
East Texas and North-Central Louisiana, Mississippi, and Alabama: Overnight Friday/Saturday morning, lows should bottom in the mid 20s to lower 30s across North-Central Louisiana, Mississippi, and Alabama (though some upper teens are possible); the lower 20s to lower 30s Saturday night/Sunday morning; and the upper 20s to lower to mid 30s Sunday night/Monday morning.
Meanwhile, across East Texas temperatures should range from the lower 30s to lower and mid 40s overnight Friday/Saturday morning, Saturday night/Sunday morning, and Sunday night/Monday morning.
Highs will range from the upper 50s to upper 60s and lower 70s each day.
Snow flurries Friday and Saturday?
Some guidance is hinting at the potential for some snow flurries and or ice sleet across parts of Alabama, Mississippi, Louisiana, and the Florida Panhandle on Friday and Saturday.
However, if either occurs, it likely will not be accumulating and won’t have much of an impact.
