Long Term
(Sunday night through Friday) Issued at 331am CST Sat Feb 15 2025

The next frontal system that moves through looks to do so by late Tuesday into Wed. This one could be a bit different as a surface low may form near the coast and move ENE. This would keep the severe weather along and south of the coast. But heavy rainfall would still be a possibility with this system as the H3 jet is still active along with the subtrop jet during that period, so flooding issues will remain on the table for this especially if there is any slowing of it. The system after mid week looks to greet the area by the start of the next week so we won't look at that until it moves into the fcast.

Marine
Issued at 331am CST Sat Feb 15 2025

SE winds of around 20kt will rise to around 25kt and continue until frontal passage shifts winds to NW while speeds remain around 25kt. As winds shift from NW to NE early Monday, speeds will begin to lower to around 10kt. Storms will accompany this front over the weekend and some of these could become strong to severe. Winds will continue to shift to E Monday then SE by Tuesday and rise to 15-20kt ahead of the next frontal system that should impact the northern gulf Tuesday night through Wed.
