GMZ400 300 Pm Cdt Fri Apr 26 2024
Synopsis - A tight pressure gradient between a series of lows over the southern plains and a surface high off the east coast will allow for a prolonged period of strong and gusty southerly winds. Sustained winds are likely to be near or above 20 knots through the weekend with gusts over 30 knots. This, along with building seas to as high as 10 feet offshore, will bring about a long duration small craft advisory conditions through the weekend. The onshore winds will decrease early next week as the high weakens off the east coast and no deep surface lows are expected to form over the southern plains.

UPDATE
Issued at 949 PM CDT Fri Apr 26 2024

Current obs across the region show a warm and muggy Friday night ongoing, with temperatures ranging from the 73 in Jasper to 78 in Lafayette, while dewpoints are in the mid 60s to mid 70s and skies are cloudy. Only real update made tonight was to tweak POPs over the next few hours to account for current trends, as a few light echoes have been moving across roughly the western half of the CWA over the last few hours. Otherwise, the forecast remains on track tonight.

SHORT TERM
(Tonight through Sunday night)

Wx map shows an intensifying and nearly stacked surface low/mid to upper level shortwave over NE, a surface high over the NE U.S.
and a tight pressure gradient between the two features all the way to the Gulf. South winds of 20 mph with gusts near 30 mph continue over SE TX/SW LA, a little less elsewhere. Satellite shows mostly cloudy skies over the region, radar not showing any precipitation over our area. Further north across NE TX, a line of showers and thunderstorms expected to remain north of the region. Low end chances of showers and perhaps a thunderstorm (20% or less) in the forecast tonight.

Saturday, strong southerly winds will continue, with the ongoing Wind Advisory from 9 AM to 7 PM CDT. The Coastal Flood Advisory from 5 AM to 5 PM CDT was extended northward to include Southern Orange county and Southern Calcasieu parish. Due to the later times of high tide further north, the ending time was extended to 5 PM CDT. No significant precipitation expected Saturday through Sunday morning, as the main area of significant lift remains just to our Northwest. Elevated southerly winds likely to continue through Sunday, with wind and coastal flood advisories necessary once again.

By late Sunday afternoon through Sunday night, expect chances of showers and thunderstorms to increase across Southeast Texas and Central Louisiana, increasing to 50-70%. Much less chances expected further southeast over South Central Louisiana.

LONG TERM
(Monday through next Thursday)

The beginning of next week is looking potentially wet and stormy as a front drifts into the region.

PWAT values are anticipated to increase into the 1.6 to 1.8 inch range across the region Monday ahead of the weak front while a short wave moves into the area. Lift from the incoming disturbance is expected to create widespread showers and storms, but mainly across the East TX Lakes across Cen LA with lesser chances toward the coast. With modest cape values some stronger storms may be possible, but the larger concern will be heavy rain as storms may be slow to move with and efficient rain producers.

Convection may linger into Tuesday, however ridging may return to the area by the middle of the week. Rain chances will decrease mid to late week, but isolated to low end scattered showers will be possible.

AVIATION
(06Z TAFS)
Issued at 1145 PM CDT Fri Apr 26 2024

A mix of VFR/MVFR cigs have prevailed through the evening, but recent obs suggest MVFR cigs are becoming more prevalent and should persist through the early Saturday morning. Southeast winds will remain elevated overnight, with the strongest winds expected at BPT/LCH (~15G25KT). Winds will strengthen again to 18-22 KT by mid to late Saturday morning with frequent gusts to 30+ KT by afternoon at BPT/LCH, and between 25 and 30 KT at AEX/LFT/ARA. A tight pressure gradient will maintain strong and gusty winds into Saturday evening. Meanwhile, MVFR cigs should improve to VFR by 16-18Z Saturday, lowering back into MVFR by 00-03Z Sunday at the southern terminals.
