(Tonight through Saturday night) Issued at 1217 PM CDT Fri Aug 8 2025 Summer-like temperatures continue this afternoon and tonight as the subtropical ridge over New Mexico continues to slowly loosen its grip over most of South Central Texas as it slides westward. Air temperatures should be a few degrees cooler (in the upper 90s) Saturday. However, with the increased moisture our feels like temperatures will be about the same as today (100-105 range). With the ridge moving westward this opens up the door for coastal afternoon showers and thunderstorms for our far eastern counties due to the seabreeze however, everywhere else should remain dry with lows mainly in the 70s. && .LONG TERM... (Sunday through Friday) Issued at 1217 PM CDT Fri Aug 8 2025 An incoming inverted trough makes its way westward from the southeast states arriving over the Texas coast by Sunday. This trough will bring with it higher chances for afternoon coastal showers and storms mainly staying east of the I-35 corridor and in the Coastal Plains during the afternoon hours. Looking ahead towards early next week, some global models are suggesting this inverted trough lingers off the TX Coast and moves northward through our area. We will have to watch this closely due to weak steering currents as our area will be sandwiched between the weakening high to our west and a developing high in the southeastern Gulf states. Continued chances for afternoon showers and storms resumes for the rest of the period mainly for the Coastal Plains. However, if the inverted trough gets hung up over our area then showers and storms could be possible for areas further west each afternoon through Wednesday. Beyond Wednesday showers and storm chances retreat back toward the Coastal Plains. Temperatures remain seasonably hot Sunday through next week with highs in the mid to upper 90s and heat indices in the 100-105 range with lows generally remaining in the low to mid 70s. && .AVIATION...
