Area Doppler radars are showing isolated light to localized heavy showers and even a few thunderstorms across Goliad County over the Corpus Christi area. This activity is forecast to move to the north for the rest of this afternoon and early evening as new showers and storms develop with the aid of the sea breeze through that time frame. Most areas are likely to stay dry, however, those Lucky ones have a chance to get a trace to one quarter inch with a few locations getting up to half inch. High's today are forecast to reach the mid to upper 90s over most places and up to 103 across the southern portion of the Rio Grande Plains. With the cloudiness and the chances of rain, heat index values are mostly likely to stay below the 108 mark. However, there is a chance for a few locations to briefly get to 108. Otherwise, partly cloudy skies are forecast for tonight with moisture increasing overnight through Saturday morning resulting in cloudy skies.

Clouds begin to dissipate mid to late morning with mostly sunny skies for the afternoon. Saturday's highs to range from the mid to upper 90s and up to 103 across the southern Rio Grande Plains.

LONG TERM

(Sunday through next Friday) Issued at 104 PM CDT Fri Aug 14 2026

The strong upper level ridge across the Southern Plains and Lower Mississippi Valley is keeping the local area dry and hot for the rest of the weekend into at least the middle of next week. Temperatures are likely running above normal values around 3 to 4 degrees. With drier air moving into the area for the period, heat index values should stay on check and below heat advisory criteria for the most part.

AVIATION

(18Z TAFS) Issued at 1212 PM CDT Fri Aug 14 2026

VFR conditions persist this afternoon through about midnight with moderate to occasionally breezy south-southeasterly winds. Gusts of 20 to 25 kt will occur at times. This afternoon has the low chance for spotty isolated showers along with perhaps a stray thunderstorm near and east of the Balcones Escarpment but overall probabilities and confidence for any impacts at the terminals is too low to include within the TAF package. Later overnight into Saturday morning should see an area of low clouds develop with MVFR ceilings. Locations near the Rio Grande, including KDRT, has lower confidence on seeing MVFR conditions and trends later for these locations after sunrise. VFR flight conditions return to all sites by Saturday afternoon.
