632pm CDT Thu July 16 2026

Issued at 234pm CDT Thu July 16 2026

A mid-level low continues to slowly move west over Central and West Texas toward New Mexico. We continue to monitor rainfall rates upstream due to possible river flooding of the San Antonio, Nueces, Frio and Rio Grande Rivers. While most of the rain has stopped we turn our attention to the after-math. The heavy rainfall across Central Texas will result in moderate to major river flooding in South Texas. Please take proper pre-cautions to avoid flooded areas and remember to turn around, don't drown!

As the aforementioned low exits the area, a mid-level ridge is expected to build over east Texas, resulting in south to southwesterly winds aloft. The wind shift will promote the development of a drier airmass over the CWA, especially into next week. For today, temperatures will remain in the upper 80's near the coast, and mid 90's out west. Expect gradual warming this weekend into the work week as heat indices climb to 100F-105F areawide.
