SHORT TERM
(Today through Sunday)
Issued at 311 AM CDT Sat May 4 2024

Not much change in the pattern today with onshore flow persisting, keeping a steady flow of low level moisture in the area. This will keep the possibility for some more of those pesky light showers, but not expecting anything measurable today. Additional Sierra Madre convection will be possible this evening into the overnight, and an isolated storm could drift across the Rio Grande late tonight. As we head into Sunday morning, a fairly potent shortwave pushes across the region, and could tap into a brief increase in deep layer moisture transiting the area. This along with the potential for a decaying MCS out of the north sagging in will add up to a 30-40% chance of showers and thunderstorms tomorrow, especially north
Overall not expecting much rain
largely under a tenth of an inch, but some thunderstorms could produce briefly heavy rainfall rates to result in some higher amounts. Northern victoria county is clipped by both a marginal risk of excessive rainfall and a marginal risk of strong thunderstorms for Sunday.

Key Messages:

- There will be a moderate to major risk of heat impacts from Tuesday through Thursday.

Ensemble guidance for next week features the development of a positively tilted 500 hPa trough extending from the Great Lakes to the southwest CONUS. Southwest flow off the terrain of Mexico will contribute to 850 hPa temperatures increasing to 25-30C Tuesday through Thursday. Meanwhile, onshore flow will continue to advect Gulf moisture into South Texas with both the NAEFS and ENS forecasting 925 hPa specific humidity above the 90th percentile for early May. This will result in hot and humid conditions during the middle of next week.

While above normal low level moisture will be in place across the region, mixing is expected to reduce humidity during the afternoon hours which will put a small damper on the magnitude of the heat, particularly out west. As a result, there is currently a 10-40% chance of maximum heat index values exceeding our Heat Advisory criteria of 110 degrees each afternoon Tuesday through Thursday, with the highest likelihood on Thursday. However, mostly sunny skies will increase heat stress beyond just the temperature and humidity alone. Accounting for this heat stress due to direct sunlight, the forecast WBGT currently indicates a High to Extreme threat of heat stress across South Texas for 4-6 hours each afternoon. Additionally, given that this will be the first prolonged stretch of above normal heat for the year, bodies will not yet be acclimated to the heat which will further increase the risk of heat illness. NWS's new experimental HeatRisk index which takes this acclimation into account has a Moderate to Major Risk of heat impacts during the middle of next week. This means that anyone without effective cooling and/or hydration will be at risk of being affected by the heat in addition to those especially sensitive to heat.

The good news is that there is hope for a respite from the heat before the endless Texas summer settles in with some model guidance brining a front through South Texas next weekend. Currently, CPC has a 60% chance of near-to-below normal temperatures next weekend through 17 May. May the odds be in our favor.

MVFR conditions noted at several sites this morning. These conditions will improve to VFR by late morning or early afternoon.
Expect gusty southeast winds to develop this afternoon. This evening into the overnight, MVFR conditions will redevelop for all sites. An isolated thunderstorm is possible west of the Rio Grande once again tonight, and there is a low chance COT or LRD could be impacted.
