New AVIATION
SHORT TERM
(Today through Thursday)
Issued at 248 AM CDT Wed Apr 30 2025
Key Messages:
- Moderate risk of rip currents today
- Moderate Heat risk in the Brush Country today
A slow moving 500 mb trough over the Desert SW will continue to move across New Mexico and over the Southern Plains. Meanwhile, several shortwaves move across the South Texas CWA extending rain chances as we head into the end of the week. Models are still hinting at a sfc trough/low developing and moving southeastward across the region to the Gulf coast, accompanied by the tail end of an LLJ, helping to provide uplift. The better dynamics remain over the Hill country, with the best chances for rain and thunderstorms. There is a low (15- 20%) chance for showers/thunderstorms across the northern Brush Country and the Victoria Crossroads this afternoon. Tonight through early Thursday, the precipitation is expected to take a break as a low-level high briefly builds over South Texas ahead of our next disturbance, but more on that in the long term discussion. Finally, expect low to moderate (15-35%) chances Thursday afternoon/evening especially closer to the Rio Grande Plains, as increased moisture interacts with PVA associated with the aforementioned shortwave.
Beach and marine hazards still exist today. We have a MODERATE risk of rip currents along with Small Craft Exercise Caution conditions.
Seas are expected to be 4-6 ft. today.
Afternoon temperatures today and tomorrow will range from the low 80s along the immediate coast, mid 80s east to around 100 out west.
Heat indices today over the Brush Country will range 100-105 degrees and there is a moderate risk of heat-related impacts. Overnight lows will hover around the low to mid 70s region-wide.
LONG TERM
(Thursday night through next Tuesday)
Issued at 248 AM CDT Wed Apr 30 2025
Key Messages:
- Rainy pattern by late Thursday/Friday continuing through Sunday.
- Marginal Risk of Excessive Rainfall Thursday night through Saturday
The first of several shortwaves slated for the latter half of the week will approach the area Thursday night. We're just starting to get into the period where some higher resolution guidance will pick this up, and at this time, mainly just the FV3 is showing what the global models suggest, and that is a thunderstorm complex approaching the Rio Grande in the evening and progressing eastward.
While most of the energy and the bulk of the convection will be north of our forecast area, some could get into the northern Brush Country. That said, other high res models - NAM, HRW aren't showing much.
Additional shortwaves will keep rain chances elevated for at least Friday and Saturday. QPF totals haven't changed much, but as mentioned previously, with high PWAT values, some higher rainfall rates will be possible and thus locally higher rainfall totals.
Guidance currently still remains mainly 0.5 to 1", but with slightly higher totals northwest where Thursday night rain is possible. GFS ensemble probs of above 1" have decreased from last nights guidance, but other ensembles still suggestion a medium chance.
Temperatures Friday cut back a notch (around 5 degrees) from the very warm (hot?) conditions Thursday, then fall farther - back into the 80s for the weekend with the cloud cover and rain potential.
Ridging builds by Sunday into Monday decreasing rain chances, but high temperatures should remain in the 80s through Monday.
