SHORT TERM
(Today through Thursday)
Issued at 414 AM CDT Wed Apr 24 2024

Key Messages:

* Breezy and adverse marine conditions developing Thursday * A High Risk for Rip Currents is in effect for Thursday

Dry weather conditions will persist through the short-term forecast period due to continued influences of a surface pressure system over the northern Gulf. A 500 mb ridge axis will move overhead today before shifting east of the forecast area on Thursday. This will allow for near normal temperatures to continue over the region with daytime highs today and Thursday in the upper 80s to mid 90s (cooler near/along the coast).

The main weather development during the short-term forecast period will be the development of strong southeast winds beginning on Thursday. Computer models continue to advertise a strengthening surface pressure gradient taking shape on Thursday with low pressure systems over north-central Mexico and a surface high over the Gulf of Mexico. This will result in strengthening boundary layer winds out of the southeast developing during the day on Thursday. Winds are expected to be strongest later in the day on Thursday.

LONG TERM
(Thursday night through Tuesday)
Issued at 414 AM CDT Wed Apr 24 2024

Generally dry and tranquil weather will prevail through the long term period. A couple of mid to upper level short waves will swing over the Plains Friday and Saturday night into Sunday. At the surface, high pressure across the region will interact with a series of low pressure systems moving across the Plains. The tight pressure gradient accompanying the aforementioned pattern will maintain strong southeast to south winds, especially for Friday and Saturday.
Friday and Saturday will be breezy to windy and could reach wind advisory criteria over the eastern third or so of the CWA, each afternoon. Breezy conditions are expected to continue across the area on Sunday. Rain-free conditions are expected through the weekend. Rain chances are expected to increase early next week due to convection from the Sierra Madre Oriental. Showers and thunderstorms are in the forecast staring Monday afternoon and night.

Temperatures will remain several degrees above normal through the period. Highs each afternoon should range from the 80s near the coast to around the mid 90s across the Rio Grande Plains under a mix of sun and clouds. Overnight lows are expected to fall into the low to mid 70s each night.

High Risk of Rip Currents will be likely Friday into Saturday.

AVIATION
(18Z TAFS)
Issued at 1218 PM CDT Wed Apr 24 2024

VFR conditions are expected at all three TAF sites this afternoon.
MVFR ceilings are forecast to return tonight, approaching IFR levels by sunrise Thursday morning. Southeasterly winds are expected to continue through the period. Wind gusts this afternoon are expected to diminish this evening, with gusts returning late Thursday morning.

MARINE
Issued at 414 AM CDT Wed Apr 24 2024

Today through Thursday...Light to moderate seas and moderate winds are expected to continue through today. A strengthening pressure gradient on Thursday will result in strong southeasterly winds developing. This ultimately will result in adverse marine conditions developing as early as Thursday with building seas and heightened rip current risk. That said, a High Risk for Rip Current Statement has been issued along the island beaches beginning Thursday morning and persisting into Thursday evening.

Thursday night through Monday...Ongoing adverse conditions are expected through much of the forecast period. Strong southeast winds will prevail Friday through Saturday, courtesy of interaction between Plains low pressure and higher pressure across the West Gulf. Small Craft Advisories will likely continue on the Laguna Madre through Saturday. Small craft should exercise caution conditions are expected to develop Saturday night and continue through Monday as winds moderate to fresh. Small Craft Advisory conditions will be likely on the Gulf through the period due to strong winds and high seas.
