SHORT TERM
(Today through Tuesday)
Issued at 242 AM CDT Mon Apr 21 2025
The most recent surface analysis indicated a stationary front over the inland western third of the BRO CWFA. Isolated to scattered convection is forecast for Deep South Texas and the Rio Grande Valley today as the proximity of this front combines with daytime heating and the approach and passage of a series of weak 500 mb disturbances overhead. The full dissipation of the stationary front and the loss of daytime heating will result in dry weather tonight. However, isolated convection will return as a possibility for Tuesday as daytime heating once again combines with mid-level disturbances. Temperature-wise, near normal daytime highs are forecast courtesy of the chance for precipitation and associated enhanced cloud cover.
LONG TERM
(Tuesday night through Sunday)
Issued at 242 AM CDT Mon Apr 21 2025
A small upper level shortwave will bring a 20% chance of showers and thunderstorms on Wednesday and Thursday of next week to the Western counties (Starr, Zapata, and Jim Hogg). Heading into the weekend, zonal flow will persist over the region and conditions are expected to dry out with no rain expected over the weekend into next week.
Winds will be southeasterly, bringing warm and humid conditions to Deep South Texas throughout the forecast period. Temperatures are expected to be warm and around seasonal, with highs in the upper 80s/lower 90s throughout the forecast period. Lows are expected to be in the 70s.
AVIATION
(06Z TAFS)
Issued at 1215 AM CDT Mon Apr 21 2025
MVFR to VFR will prevail at the aerodromes through the next 24 hours. A TEMPO has been added for convection based on the latest HRRR model data. Light winds and mostly cloudy skies will also prevail.
MARINE
Issued at 242 AM CDT Mon Apr 21 2025
Today through Tuesday...Buoy 42020 reported east-southeast winds around 4 knots with seas slightly under 6 feet with a period of 9 seconds at 1:20 CDT/6:20 UTC. Improving marine conditions will occur through the period as a nearby stationary front dissipates and high pressure becomes more of a factor over the western Gulf of America. Although generally moderate winds and seas are forecast along the Lower Texas Coast, seas may be initially high enough to warrant a Small Craft Should Exercise Caution today for a portion of the lower Texas coastal waters.
Tuesday Night through Monday...Southeasterly winds will prevail, and conditions should be slightly adverse Tuesday night through Friday.
On Friday, winds will slightly increase and seas will slightly build and small craft may need to exercise caution. Conditions will slightly improve on Saturday and Sunday, but SCEC conditions may be possible again on Monday as winds and sea heights build again.
