KEY MESSAGES

- Elevated fire danger concerns will persist through early next week due to very dry ground conditions and low humidity each day.

DISCUSSION

Issued at 345 AM CDT Thu Oct 22 2026

The forecast is very straight-forward through the next week, and confidence is therfore high in the forecast details. Global model ensembles agree that an anomalously warm upper level ridge will slowly shift eastward across the lower Mississippi Valley region as we finish up the week and go into next week. This will lead to a continuation of dry weather with large diurnal temperature ranges appoaching 40 deg F. Of greatest importance, the continued drying of vegetation combined with exceptionally low daytime RH values will help to maintain an elevated fire danger threat. We will continue to message this through the graphics and fire danger statement. Wind should have less influence and be a smaller factor in determining the fire danger threat levels. Otherwise, rainfall is not expected until late next week at the earliest, when the ridge shows signs of breaking down. /EC/
