Synopsis for the middle texas coastal waters -
high pressure to the east and low pressure to the west has strengthened our onshore flow this afternoon so that a small craft advisory is in effect until 100 am Saturday morning. However, the high pressure will nose into the coastal bend overnight allowing the flow to weaken. Weak to moderate onshore flow will continue through next week. The persistent onshore flow will result in seas of 3-6 feet continuing into early next week.

SHORT TERM
(Tonight through Saturday night)
Issued at 315 PM CDT Fri May 3 2024

Key Messages:

- There is a low chance for isolated severe storms across the western Brush Country late this afternoon through late this evening.

Main concern is this evening with the chances for thunderstorms, and whether they will become severe. High pressure is off to the east centered over Mississippi, and a sfc low is in northern Mexico. The pressure gradient has tightened over the Coastal Bend, and caused the winds to increase for a time this afternoon and into the evening. Thunderstorms are beginning to break out in the Big Bend region with the sfc trough that is aligned with the Rio Grande Valley. The HRRR/ARW/FV3 seem to have a good handle on this, with the GFS and ECMWF as well, but the larger models have weaker precipitation. Between 00z and 03z the storms are expected to move into northern Webb and Lasalle counties and move toward the southeast, but as they do the sfc high in Mississippi, is expected to build to the southwest, into the Coastal Bend, eastern Brush Country, and Victoria Crossroads. The models expect that the thunderstorms will get stopped by the sfc high, or pushed south down the Rio Grande Plains. The NAM barely has the thunder getting into the region, before it gets squashed. The only thing overnight then is isolated showers, and with the PWAT around 1.5" or better, a shower here or there is a low chance (<20%). Saturday, the front north of the Hill Country looks to remain there, with chances for rain to move south low (<10%), as the sfc high remains along the Coastal Bend. Saturday night, the models begin to move the front.
the GFS pushes most of the thunderstorms to the east with the isolated to scattered (15-40% chance) showers creeping into the Brush Country. ECMWF pushes it a bit south and has a 500 mb shortwave that runs over the western part, kicking off rain in the western Hill Country, and getting rain into the Brush Country overnight. The NBM has a blend of the two solutions with slight chance to chance pops (15-40%) From Victoria to Laredo and locations north.



LONG TERM
(Sunday through next Thursday)
Issued at 315 PM CDT Fri May 3 2024

Key Messages:

- Increasing risk of heat related impacts next week

Conditions begin with a low to medium chance (30-45%) for scattered thunderstorms Sunday. This will be due to some above normal PWAT values around the 99th percentile along with some associated energy from a upper level disturbance moving across the region to the north. The caveat with these storms will be the solid CIN values across the area which should largely keep things in check. The northern Brush Country and Victoria Crossroads should have the best chances for any convection due to some breaks in higher CIN values.

Temperatures will warm after the disturbance clears and expect our next shot of summer weather by Tuesday. Unfortunately, heat indices will be in the 110-115 degree range across the Coastal Plains and Brush Country Tuesday through Thursday. Therefore, heat stress related impacts will likely occur and the proper preparations should be done in advance.

AVIATION
(18Z TAFS)
Issued at 100 PM CDT Fri May 3 2024

Isolated showers are in the Victoria Crossroads, and the chances are expected to remain low (chance <30%) that at VCT, CRP, and ALI. In the meantime, MVFR CIGs are expected through the evening, until the low clouds and fog move back into the region overnight.
An area of thunderstorms is expected to develop in the Rio Grande Valley to the north or along the Sierra Madre and move southeast into COT and LRD after 00z/SAT and last through about 03z/SAT before they die off or move out of the forecast area. The rest of the night will have MVFR to IFR CIGs and probably MVFR to VFR VSBYs as the moisture remains high overnight. Ceilings will rise late in the morning to MVFR, and possibly VFR.

MARINE
Issued at 315 PM CDT Fri May 3 2024

High pressure to the east and low pressure to the west has strengthened our onshore flow this afternoon so that a Small Craft Advisory is in effect until 100 AM Saturday Morning. However, the high pressure will nose into the Coastal Bend overnight allowing the flow to weaken. Isolated to scattered thunderstorms are expected during the day Sunday. Weak to moderate onshore flow will continue through late next week with seas around 3-6 feet.
