New AVIATION

SHORT TERM
(Tonight through Sunday night)
Issued at 200 PM CDT Sat Jun 1 2024

Key Messages:

*Above normal high and low temperatures *Best chance for rain on Saturday

An upper level ridge will continue to be the driving force for the weather of Deep South Texas and the Rio Grande Valley. The subsidence from the ridge along with the onshore flow will support greater than normal temperatures with highs in the range of the upper 90s for the coastal regions and triple digits for the rest of the area. Another effect of the onshore flow will be the transport of low-level moisture to the region that will increase the humidity in the area as well. This will further drive up the heat indices for the short term period, as such, the heat indices are expected to be in the range of 108 to 114 for tomorrow. However, the need for a Heat Advisory for tomorrow is questionable at best. Current model analysis does not show the heat indices being elevated long enough to warrant a Heat Advisory being needed, however a Special Weather Statement might be issued instead. Low temperatures will continue to be elevated for this time as well. With low temperatures in the low 80s for tonight and tomorrow night.

The presence of the ridge will continue to bring plenty of dry air and stability to the atmosphere that will hinder the development of showers and thunderstorms. At this time, short term forecast period appears to be rain free for Deep South Texas and the Rio Grande Valley.

For those going to the beach, a High Risk of Rip Currents is currently in effect, but is expected to shift to a Moderate Risk tonight and tomorrow.

LONG TERM
(Monday through next Saturday)
Issued at 200 PM CDT Sat Jun 1 2024

The 500mb ridge of high pressure builds and works into West Texas through the long term, 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 generally below 15 percent through the long term, except around 15 percent for Zapata County Monday evening, with a weak mid-level disturbance potentially helping some Sierra Madre convection flare up. May see one or two storms again pop up across the border Tuesday and Wednesday nights as well, with limited rain chances across the brush country.

Otherwise, expect heat to increase and breezy winds continuing into Monday but gradually dissipating and dropping off to light or nearly calm by the end of the week 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 nearly every afternoon in some capacity. Some drier air arriving late week into the weekend may help keep most Heat Indices below 110.

AVIATION
(00Z TAFS)
Issued at 603 PM CDT Sat Jun 1 2024

VFR conditions will continue into early evening. Low clouds will begin to move in over the next couple of hours with ceilings falling to MVFR for all aerodromes through the overnight hours.
VFR conditions will return Sunday by mid to later morning.
Southeasterly winds will relax some tonight, but expected to increase again by Sunday afternoon with gusts up to 30 kts.

MARINE
Issued at 200 PM CDT Sat Jun 1 2024

Tonight through Sunday Night...High pressure over the Gulf of Mexico and a thermal low over Central Mexico will continue to generate an enhanced pressure gradient over the Lower Texas Coast. This will support light to moderate southeasterly winds and moderate seas through Sunday night. Small Craft Exercise Caution conditions are likely through the period and some Small Craft Advisories cannot be ruled out tomorrow for the Laguna Madre and nearshore Gulf waters.

Monday through Saturday...Breezy southeasterly winds will maintain elevated seas and Small Craft Caution to potentially Small Craft Advisory conditions across the coastal waters, especially the nearshore Gulf and Laguna Madre into Tuesday. 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 into next weekend.
