Area Forecast Discussion...UPDATED National Weather Service Brownsville TX 610 PM CDT Sun Jun 2 2024

New AVIATION

SHORT TERM
(Tonight through Monday night)
Issued at 148 PM CDT Sun Jun 2 2024

Key Messages:

*Above normal high and low temperatures

The main message of the short term forecast period is that the temperatures are going to remain above normal. The mid-level ridge will continue to drive subsidence into Deep South Texas and the Rio Grande Valley, which will lead to the middle and upper levels of the atmosphere dry and stable. This atmospheric set up will keep the rain away from the area for the short term forecast period.
Meanwhile the southeasterly winds will continue to bring in plenty of low-level moisture that will make the air very humid. Also thanks to an enhanced pressure gradient due to the interaction of high pressure over the Gulf of Mexico and a thermal low over central Mexico. While the winds are expected to be gusty through the period, they should remain below Wind Advisory criteria.

As for the heat, the high temperatures for tomorrow are expected to be in the range of upper 90s for the coastal regions, while the rest of the region is in the triple digits. Thanks to the surface southeasterly winds and the humidity, the air is going to feel hotter outside with the heat indices in the range of 110 to 114 for tomorrow. A Heat Advisory may not be needed for tomorrow as the duration of larger heat indices seems to be very borderline at this point, so that a Special Weather Statement would be sufficient. As for the low temperatures, are expected to be in the low 80s.

LONG TERM
(Tuesday through next Sunday)
Issued at 148 PM CDT Sun Jun 2 2024

The 500mb ridge of high pressure builds and works into West Texas through next weekend, continuing to bake Deep South Texas through the week, as a persistent and potent trough continues much cooler weather across the Great Lakes and Northeast. The chance of rain remains less than 10 percent through the long term, with only an outside shot at a storm or two off the Sierra Madre into the brush country Tuesday night or Wednesday night and some streamer showers or storms offshore late week into the weekend.

Otherwise, expect heat to increase into Wednesday and persist through the long term period. Breezy winds Tuesday drop off to light or nearly calm by the end of the week and weekend as the ridge of high pressure moves northwest. Overnight lows remain generally in the 80s across the Rio Grande Valley, offering very little recovery from conditions. Heat Advisories will be most likely Tuesday and Wednesday, but may be needed Thursday as well.
Some drier air arriving late week into the weekend may help keep most Heat Indices below 110.

AVIATION
(00Z TAFS)
Issued at 609 PM CDT Sun Jun 2 2024

Through 00z Tuesday....As of this update, VFR conditions were taking place at the TAF sites under a SCT-BKN deck of strato-cu clouds as depicted on satellite with unrestricted visibilities. VFR conditions will continue through this evening. Tonight, there's the potential once again for MVFR ceilings to develop. During the day on Monday, VFR conditions are expected to return.

Southeast winds 12-20 kts with gusts between 25-30 kts are expected to prevail through the 00z TAF cycle.

MARINE
Issued at 148 PM CDT Sun Jun 2 2024

Tonight through Monday Night...Moderate to fresh southeasterly winds with moderate seas due to an enhanced pressure gradient. These conditions will result in the need for Small Craft Exercise Caution.
A low end Small Craft Advisory cannot be ruled out either as the strength of the winds is borderline at this point.

Tuesday through Sunday...Breezy southeasterly winds continue Small Craft Advisory conditions Tuesday into Tuesday night across the coastal waters, especially the nearshore Gulf and Laguna Madre. As high pressure builds into West Texas through the week, expect winds to gradually diminish, allowing seas to subside into late week, with generally favorable marine conditions returning to the lower Texas coast late week through next weekend. The chance of streamer showers or storms across offshore waters gradually increases each night Wednesday through Sunday.
