DISCUSSION
Issued at 1114 AM CST Tue Nov 11 2025
Warm and dry conditions are expected through the forecast period. High pressure sliding east has allowed southeasterly winds to return to the region with temperatures warming through the week. While today highs will be in the upper 70s to low 80s, tomorrow temperatures will be back above normal in the mid to upper 80s. Temperatures will continue to climb with 90s returning to much of the region by this weekend. Temperatures cool only by a few degrees through early next week, with temperatures in the upper 80s north and east and low 90s across the upper Valley and Rio Grande Plains. Overnight lows in the mid 50s to low 60s tonight will be back into the 60s and 70s by Saturday.
A cold front will approach Deep South Texas late this weekend, and latest guidance does not have this front moving through the region but stalling just northwest of the CWA on Monday before washing out. This front will have little to no impact across the CWA.
A moderate risk of rip currents returns for Wednesday and moderate to high for this weekend.
