New AVIATION
SHORT TERM
(Today through Thursday)
Issued at 254 AM CDT Wed Apr 30 2025
Today and Thu will be almost diddo. The difference will be the addition of some sh/ts late Thu. This will be good in the way that we could use some rain. But if these storms stall, they could dump some high precip numbers. The larger MSC feature that is shown to move in late Thu is advertised to decay as it does so. But outflow boundaries could produce new activity around and there is an outside chance that one of these could be strong/severe.
LONG TERM
(Thursday night through Tuesday)
Issued at 254 AM CDT Wed Apr 30 2025
A front will move into central TX and stall Thu while another front moves in from the north and stalls near the LA/AR line Fri. The storms that develop along this front will cold pool out and continue to refire southward into the area by late Fri and Fri night. Some of these could be strong as well. Diurnal instability will keep rain chances high going through the weekend. There is evidence that the stalled front over northern LA/central MS will filter into the area by Sun or Mon. This would help keep precip numbers higher than normal but will eventually begin to weaken its thermal boundary into mid next week.
AVIATION
(12Z TAFS)
Issued at 628 AM CDT Wed Apr 30 2025
Most terminals are VFR currently outside of MCB. MCB is currently impacted by low visibility and ceilings but should begin to improve up to MVFR/VFR in the next 2-3 hours. Ceilings will lift during the daytime but will begin to lower again tonight bringing terminals to low VFR with dips into MVFR possible. Winds will be generally southerly to southeasterly with gusts up to 15 knots.

MARINE
Issued at 254 AM CDT Wed Apr 30 2025
Winds will remain southerly around 15kt into the weekend. Wind speeds my lower Sat and even become light northerly Sat night into Sun. Winds should shift to easterly by Mon and remain easterly at around 10kt through mid next week. There is the potential for a few sh/ts over the coastal waters through the weekend.
