- The very slight cooling trend has shifted later again, with highs only in the low to middle 90s late next week, and more overnight lows in the 60s.

DISCUSSION

Issued at 1132 AM CDT Fri Sep 18 2026

A closed upper-level high continues to meander westward over northeast TX at the time of writing. Synoptic subsidence will work to keep showers at bay. While temperatures will still remain in the upper 90s through the weekend, drier air is being ushered in by the high pressure and should help keep heat indices well below Heat Advisory criteria. Recent surface observations already have reported dew points in the 60s at most sites, which is much sooner in the day compared to previous days. This relative comfort will increase preexisting fire weather concerns and drought conditions. People should monitor local official guidance on any burn bans in place. The lower humidity will luckily help cool things off during the evening hours, allowing temperatures to drop in the low 70s instead of the upper 70s of recent days.

The pattern change that has been the focus of recent discussion continues to surprise. The ridge over the region is still expected to weaken during the early part of next week, largely keeping the low in the Northern Plains at bay. However, both the Euro and GFS's 6z run depict a mid-level vort max around southeast OK Monday morning. Should this verify, there could be enough forcing to organize some rain in the northwest part of the region even without the influence of the low up north. The NBM has continued to cut back on rain coverage but increased the existing rain chances on Monday, suggesting some level of increasing confidence.

After the rain on Monday, conditions remain dry for the rest of the forecast period. But the low moving through the Northern Plains is expected to continue toward the Midwest by midweek and hopefully usher in some slightly cooler temperatures. Even if fall isn't here yet, temperatures in the low 90s will certainly be better than triple digits.
