DISCUSSION

Issued at 214 PM CDT Sat Oct 17 2026

The upper level trough the helped usher in the cooler temperatures will continue shifting east and ridging aloft will build into the region from the west through Sunday. Latest surface analysis had a 1032mb high centered over the mid Mississippi valley that will also shift east but continue to ridge back across our region. This will result in a lighter wind Sunday but temperatures will top out several degrees warmer than today. The result will be critically low afternoon minimum relative humidity maintaining fire danger concerns. /22/

Sunday Night through Friday...High pressure at the surface centered to our north and increasing ridging aloft from the west, will maintain quiet weather across the forecast area through the mid and extended forecast periods. While the overall dry air mass will remain across the region through the week, temperatures will steadily warm each day. These increasing temperatures in this dry air mass causing afternoon minimum relative humidity values to fall to critically low values, coupled with the extremely dry soil conditions across the area, are expected to again promote dangerous fire conditions across the forecast area through much of the work week. Please continue to monitor the latest forecast and outlook, as appropriate fire weather hazards/products will likely be needed and issued for portions of and eventually all of the forecast area during this timeframe, particularly Tuesday through Friday. /19/
