DISCUSSION

Issued at 116 AM CDT Tue Sep 22 2026

No change from the previous forecast. The NBM has continues to show a 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. 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.
