Area Forecast Discussion...UPDATED National Weather Service Brownsville TX 1233 AM CDT Mon Jun 16 2025
New AVIATION
SHORT TERM
(Now through Tuesday) Issued at 1101 PM CDT Sun Jun 15 2025
In the big picture...no change to the sensible weather through the period. Other than isolated afternoon sea-breeze enhanced showers/thunderstorms Monday across the Brooks/Kenedy area, conditions should remain rain-free with a continuation of seasonably hot (for June 16-17) afternoons and steamy overnights.
Despite the presence of a very weak shear axis between 500 mb subtropical ridges over Florida/Bahamas and northwest Mexico/New Mexico (out to Baja California), dry air off the surface should mix down by afternoon each day to preclude heat index values exceeding 110...in fact, if today is an indicator of trends, dew points will drop to near 70 over the mid Valley and lower 70s along IH-69E/US 77, sufficient to keep values between 103 and 108 which is about average for this time of year in this pattern.
As for precipitation...have left the slight chances of streamer showers pinned to the coast early Monday, with isolated showers/perhaps a thunderstorm favoring the northern ranchlands Monday afternoon. A mid-Sunday evening cluster of storms rolling across the Coastal Bend may leave some boundaries behind that could aid late morning redevelopment in Brooks/Kenedy...which will need to be watched.
Beach conditions overall should be ideal, with comfortable surf a relief from the inland heat. That said, rip/longshore current intensity will be on the edge of moderate, so swimmers should remain aware of their situation over the next two days.
LONG TERM
(Tuesday Night through next Monday) Issued at 1101 PM CDT Sun Jun 15 2025
Tuesday night and most of Wednesday continue more of the same, with a continued expected arrival of deeper layer moisture along the coast and across the Gulf waters by late Wednesday afternoon.
This will allow an increasing chance (though still low) for onshore showers, perhaps a thunderstorm, before sunset. Still plenty hot inland but dewpoints in the low 70s by mid to late afternoon should keep heat index values in check.
The one difference this evening compared with the last two is the organization of timing of the tropical-upper tropospheric trough (TUTT). Both GFS and ECMWF deterministic are rather bearish on the intensity of the "inverted" trough, which makes forecasting the total amount of rainfall (and location thereof) even more difficult than what appeared a couple days ago. That said, the trend remains the same - enough cloud cover, deep layer moisture, and favorable situation on the east side of whatever comes of the TUTT to favor at least likely chances (60-70 percent) with highest rain totals favoring Cameron and Willacy for Thursday through Saturday.
In a way, this would be good news, since most of these areas have missed the recent rains the past two weeks but have been plenty hot and breezy and on the edge of abnormal dryness. Total QPF through Saturday has dropped a bit, now closer to 1-1.5" along/east of IH-69C and 1.5-2" east of IH-69E, but uncertainty remains with some model blends chances continuing at 30-40+% for 3"+ in Cameron/Willacy between Thursday and Sunday morning.
Bottom line for drainage clearing remains the same: take advantage through early Wednesday in case conditions go downhill thereafter.
AVIATION
(06Z TAFS)
Issued at 1231 AM CDT Mon Jun 16 2025
Generally VFR will prevail at the aerodromes through the next 24 hours. Light winds with a few clouds for the remainder of the overnight hours will become breezy with partly cloudy skies on Monday. Winds will then diminish and clouds will thin beginning around sunset.
MARINE
Issued at 1101 PM CDT Sun Jun 15 2025
Now through Tuesday: Little change from today, right through Tuesday: Modest winds, generally 10-15 knots across the Gulf and Bay but periodically 15 knots and gusty across Laguna Madre each afternoon and the Gulf for a short window overnight. Seas should remain at 3-4 feet with a moderate chop overall on the bay, as pressure gradients are unchanged, diurnally. Other than isolated to scattered mainly offshore showers and perhaps a thunderstorm, conditions should be rather quiet.
Tuesday Night through Friday Night: The main issue will remain increasing rain chances and coverage as the aforementioned upper level TUTT makes its move across the Mexican coast and west of the area. For now, better coverage still looks to be Thursday through Friday night with periodic lulls. Background winds may veer a touch to the east-southeast but speeds don't pick up any...however, in and around stronger cells that would change, along with increasing wind chop.
Seas begin at 3-4 feet through Wednesday night and may climb to 4-5 feet, especially in agitated conditions in coverage showers/storms, but latest forecast has backed off Caution (6 foot) levels at this time.
