KEY MESSAGES

Issued at 616 PM CDT Mon Sep 21 2026

- Low (20-35%) chance of showers and storms continue this week.

- Above-average temperatures remain through the forecast period.

DISCUSSION

Issued at 122 PM CDT Mon Sep 21 2026

NBM has finally joined the rest of the group with low (15-30%) daily rain chances through this week, mainly along the coast and over the Coastal Plains. A few showers and storms could develop along the afternoon seabreeze each afternoon, which could push showers a bit further inland, so we will continue to monitor development.

Temperatures will be above average through the week (surprise, surprise). The good news is that heat index values will generally remain below 110 across the area. Even so, it is important that we all continue to practice heat safety: take breaks when outside, drink plenty of water, and look before you lock.
