316 FNUS28 KWNS 012151 FWDD38 Day 3-8 Fire Weather Outlook NWS Storm Prediction Center Norman OK 0449 PM CDT Wed Oct 01 2025 Valid 031200Z - 091200Z ...Day 3/Friday... A strengthening upper-level trough over the West along with a deepening lee trough across the Northern Plains will promote slightly increased southerly winds across much of the Great Plains and Upper Midwest, where well above normal temperatures will contribute to dry fuels across the region. Enhanced downslope southwest winds and drying on the nose of strong mid-level jet will support an increased fire weather threat across northeastern WY, southeastern MT and western SD where dry fuels and ongoing curing of fine fuels could support wildfire spread. A 40% probability for critical fire weather conditions was added to identify this threat. ...Day 4/Saturday... Upper-level trough across the Intermountain West and strengthening lee cyclone/trough across the Dakotas will continue to support a swath of strong south/southwest flow from the southern High Plains into the Upper Midwest. Dry and breezy south to southwest winds over increasingly dry fuels with expected ERC percentiles above 90th percentile across portions of the Midwest, should yield an increased fire weather threat across portions of far northern NE, eastern SD and southwestern MN where fuels are most receptive. A 40% critical probability for wind/RH was introduced for Day 4/Saturday. ...Day 5-8/Sunday-Wednesday... Dry, southwest flow ahead of persistent upper-level troughing or potential cut-off low across the western U.S. should sustain dry and breezy conditions over portions of the Great Basin and Lower Colorado Basin through the middle of next week. Although the synoptic setup supports elevated fire weather threat, fuel conditions are anticipated to remain benign, limiting overall fire weather concerns in the long term. Farther east, surface low pressure across the Midwest will quickly translate northeastward into Canada while high pressure settles into the Great Lakes region serving to relax surface pressure gradients and winds. ..Williams.. 10/01/2025 ...Please see www.spc.noaa.gov/fire for graphic product... $$
