Area Forecast Discussion...UPDATED National Weather Service Brownsville TX 617 PM CDT Sat May 4 2024

New AVIATION

SHORT TERM
(Tonight through Sunday night)
Issued at 224 PM CDT Sat May 4 2024

The main event continues to be the above normal temperatures for Deep South Texas and the Rio Grande Valley. The high temperature for tomorrow is expected to be mostly in the 90s for the area, while parts along the coast and the beach will be in the upper 80s. While the overnight low temperatures for tonight and tomorrow night are expected to be in the 70s. The overall light southeasterly flow will allow for low-level moisture to move into the region, that could help to produce some patch fog mostly in the Northern Ranchlands and along the coast and beaches around daybreak. A patchwork of low- level to upper-level clouds are expected through the duration of the short term forecast period, which may provide some relief from the warm temperatures.

Currently, SPC has the Northern Ranchlands in a general thunderstorm outlook. While it is certainly possible that some showers and thunderstorms could drift in from the north to the region, they would be moving into an unfavorable environment as the upper levels of the atmosphere are still very dry. As such, rain chances have been left at isolated for the Northern Ranchlands to account for any stray showers and thunderstorms that make it into the area.

Meanwhile, at the beaches, moderate seas will continue to produce a Moderate Risk of Rip Currents at the local beaches through Sunday.

LONG TERM
(Monday through next Saturday)
Issued at 224 PM CDT Sat May 4 2024

Heat will become more problematic in the long term. Temperatures have been running around 5 degrees above average lately, but differences from average Tuesday through Thursday could increase to a positive 10 degrees. A dryline will set up shop to the west, never really penetrating very far into the CWA, but at the same time moderate to fresh southeast breezes will pump high dew point (in the 70s) air inland, placing an upward stress on heat index values.

The mid-level pattern will remain rather zonal most of the week, but ridging will become more apparent heading into next weekend.
Weather systems will thus, for the most part, avoid this part of the world through the week yielding a dry forecast. Partly to mostly cloudy skies will generally prevail, with increased sunshine taking over each afternoon. Marginal heat advisory conditions could develop Tuesday, Wednesday, and again Thursday afternoons for portions of the CWA

Wildfire fuels are in transition (drying trend), but do not see any obvious fire weather threat days just yet. Rip current risk will likely remain at least moderate, given the wave height and swell period forecast.

A cold front may push into the area next Friday ahead of the building weekend ridge, and that could be enough to trigger convection moving out of the Sierra Madre Orientals and into the Upper Valley Friday evening to Friday night. The high pressure building in behind the front may provide a temporary relief from the heat.

AVIATION
(00Z TAFS)
Issued at 613 PM CDT Sat May 4 2024

MVFR conditions are expected to generally prevail through the TAF period with southeasterly winds. VFR ceilings may return at all three aerodromes Sunday, with MVFR a little more persistent at BRO and HRL.

MARINE
Issued at 224 PM CDT Sat May 4 2024

Tonight through Sunday Night...Moderate southeasterly winds and moderate seas are expected to persist along the Lower Texas Coast.
Small Craft Exercise Caution conditions are expected to occur through the period.

Monday through Thursday night...Moderate to fresh southeast breezes will prevail through the long term. With those winds will come moderate to occasionally higher wave heights. Thus, expect here and there small craft should exercise caution to low end small craft advisory conditions. Synoptically, high pressure over the North Gulf will interact with lower pressure upstream to maintain a gradient supportive of moderate to fresh winds.
