SHORT TERM
(Tonight through Wednesday night)
Issued at 345 PM CDT Mon Mar 18 2024
Clear, cool and blustery conditions are ongoing across the region in the wake of a passing cold front. (Your time is coming, spring.
Let us have this last taste of winter.) A Wind Advisory has been issued for coastal Texas, southwest Louisiana and south central Louisiana until 5 PM for strong northerly wind gusts. This evening, the pressure gradient relaxes and high pressure starts moving into the south central US. Winds will diminish and conditions improve further under nearly clear skies.
Tonight, much cooler conditions are expected. Once winds come down, expect temperatures to drop quickly. Temperatures will drop into the lower to mid 30s north of I-10 and low to mid 40s along the coastline. Such cool temperatures and calm conditions should result in areas of light frost development between midnight and sunrise across central Louisiana. Areas expecting the most widespread frost are Evangeline, St. Landry, Rapides and Avoyelles parishes.
Uncertainty does exist as to whether these areas will actually reach 32 F. Conditions do give the indication that radiational cooling will maximize tonight, with the question being just how far temps can cool. There is about a 30 to 40 percent probability of the aforementioned parishes hitting 32 F just prior to sunrise.
In the interest of communicating this risk of this happening, the previous Frost Advisory was upgraded to a Freeze Warning from midnight to 9 AM Tuesday morning.
Expect clear and cool conditions Tuesday during daytime hours as high pressure moves right overhead. The high shifts east on Wednesday, opening the door to moisture return and warming temperatures near 70 F. Late Wednesday, an upper shortwave swings into the lower Plains states. Broad, large scale ascent spreads over the region from aloft, aiding the return of light showers over southeast Texas after midnight Wednesday.

LONG TERM
(Thursday through next Sunday)
Issued at 220 PM CDT Mon Mar 18 2024
Uncertainty remains above average regarding a storm system passing through the region Thursday/Friday. The main differences are timing and location of heavier rainfall. Taking a blend and probabilistic approach will keep POPs into Friday. Probability of greater than 1" for the 24 hr period late Thursday into Friday is roughly 10-35% with 10-20% of greater than 2". Onshore, the area with the greatest probs are across SWLA/SETX. However, the heaviest rainfall appears to favor offshore with the potential for SFC low development in the northern GoM.
Thereafter, drier and warmer weather expected generally Friday through Sunday. Another storm system is possible early next week, but confidence remains low at this time.

SCT/BKN cirrus layer ~25000 ft expected to continue this evening, gradually thinning out overnight and Tuesday. Main forecast issue will be winds. Expect the north winds presently around 16-18 kts with gusts to 25-28 kts to diminish rapidly this evening to near 5-8 kts, and around 5 kts southern terminals, calm at AEX after 06z. At AEX, expect light and variable winds for the remainder of the period. For the southern terminals, expect east winds around 6-8 kts after 15z Tuesday, becoming southerly by the afternoon.
