KEY MESSAGES

Issued at 207 AM CDT Tue Sep 8 2026

- Moderate to Major risk of heat-related impacts each afternoon

- Low chances (10-30%) for seabreeze-driven showers and thunderstorms Tuesday and Friday. Greater chances (20-45%) Wednesday and Thursday.

DISCUSSION

Issued at 207 AM CDT Tue Sep 8 2026

We'll maintain a low chance for showers and thunderstorms along the seabreeze this afternoon as heat indices once again will flirt with Heat Advisory conditions, peaking around 110 over the Coastal Plains. Heat will remain our primary concern each afternoon this week, all are urged to continue practicing heat safety.

Rain chances increase (20-45%) Wednesday and Thursday as an inverted mid-level trough (or low) over the Gulf moves westward into South Texas, increasing PWAT values to near 2.25" (90th percentile) and enhancing lift support. Greatest coverage is expected over the Victoria Crossroads. A series of weak mid-level disturbances along the southern periphery of the ridge will keep at least low rain chances over the Coastal Plains through this upcoming weekend.
