New AVIATION

SHORT TERM
(Tonight through Friday night)
Issued at 124 PM CDT Thu Apr 17 2025

Key Messages:

- Wind Advisory for the Coastal Bend in effect through 9 PM.

Onshore surface flow will persist through the short-term period, supporting a continued increase in low-level moisture and cloud cover across the region. Aloft, an upper-level ridge will remain in place, gradually shifting eastward late Friday into the start of the weekend. This ridge will help suppress convective development, resulting in net-zero rain chances for the time being. The increasing cloud cover will also limit radiational cooling overnight, keeping low temperatures in the upper 60s to low 70s tonight and Friday night.

Persistent south-southwesterly mid-level flow will promote drying and warming at the 850MB level. This warmer, drier air is expected to mix down to the surface, leading to another warm day across the region on Friday. High temperatures will approach the triple digits along the Rio Grande and rise into the 90s across most of the CWA Slightly "cooler" conditions, with highs in the mid to upper 80s, will be in place across the eastern Coastal Bend and up into the Victoria Crossroads.

The primary concern over the next 24-48 hours will be the wind. A tightening pressure gradient combined with a strengthening LLJ, will support wind speeds aloft reaching 40-50 knots. These stronger winds will mix down to the surface, resulting in another breezy day on Friday, with gusts between 30-40 mph. As such, another Wind Advisory appears likely tomorrow, but will have the evening crew see what the latest data is indicating.

LONG TERM
(Saturday through next Wednesday)
Issued at 124 PM CDT Thu Apr 17 2025

Key Messages:

- Windy conditions continue Saturday with peak gusts approaching 35 mph over the Coastal Plains.

- 25-45 percent chance of showers and thunderstorms each day, Sunday through the middle of next week.

Saturday, a weak, cold front will move into South Texas with a 500 mb trough over New Mexico. The pressure gradient will tighten up once again during the day and produce another windy afternoon. The probability for sustained winds over 20 MPH is likely (70-90%), and wind gusts past 35 MPH a medium chance (40-60%). As the front moves closer, most of the forcing with the front will wash out as the 500 mb trough kicks northeast into the Texas Panhandle. The remnants of the cold front will reach the Middle Texas Coast on Sunday, and looks to linger over the region into the middle of next week. While there is little thermal support for the front the sfc trough remains as 500 mb shortwave trough pass through the region. This will keep the low chance (20-35%) for showers and thunderstorms over the Coastal Bend through Thursday, before high pressure finally pushes the front out. The ECMWF also has a building 500 mb ridge over us on Thursday, while the GFS has another shortwave trough over the region. The GFS would continue showers into Thursday and Friday.
Like the ECWMF idea, but that is 7 days out so either scenario is plausible. The NBM as low chance (15-25%), Thursday, due to the uncertainty.

AVIATION
(06Z TAFS)
Issued at 1226 AM CDT Fri Apr 18 2025

Currently have a mix of VFR/MVFR conditions across South Texas.
Expecting mainly MVFR CIGs overnight with eastern terminals hanging on to MVFR ceilings through the morning hours into the early afternoon before returning to VFR. Expect gusty southeast winds to continue overnight with gusts up to around 25 knots tonight, increasing to around 35 knots tomorrow afternoon. MVFR ceilings should re-develop again across eastern sites tomorrow evening.

MARINE
Issued at 124 PM CDT Thu Apr 17 2025

Fresh to strong southeasterly winds (BF 5-6) will persist through Friday with seas generally 5-8 ft over the Gulf waters. Saturday into Sunday, winds will weaken to a moderate to fresh breeze (BF 4-5) followed by a gentle to moderate breeze (BF 3-4) Monday. As a weak, cold front moves into South Texas, on Monday, the winds will also back to the east. There will be a 25-45% chance of showers and thunderstorms on Sunday with the best chances over the northern waters. Lower shower and thunderstorm chances will linger through middle of next week.

FIRE WEATHER
Issued at 124 PM CDT Thu Apr 17 2025

Generally improved fire weather conditions can be expected across the Western Brush country tomorrow, as minimum RH's increase to around 30%. However, paired with southeasterly winds at 20-30 mph and gusts as high as 40 mph, elevated fire weather conditions will still exist. The elevated fire conditions may continue into Saturday over the Rio Grande Plains. However, improving fire weather conditions can be expected this weekend can continue through the middle of next week as the minimum relative humidity creeps up slightly and the winds decrease after Saturday.
