See the previous discussion for additional information. ..Wendt.. 10/03/2025 .PREV DISCUSSION... /ISSUED 0150 AM CDT Fri Oct 03 2025/ ...Synopsis... A strong upper low is forecast to transit from the West Coast into the Great Basin and Intermountain West today. Accompanying the trough, strong south/southwesterly flow aloft will overspread the central and northern High Plains deepening a lee low and surface trough over eastern MT and the western Dakotas. This will support strong west/southwesterly downslope winds across portions of WY, the Dakotas and southern MT through this afternoon. Peak winds of 15-25 mph are likely. Accompanying the dry downslope winds, record warm temperatures and deep mixing will favor low afternoon humidity around 15-20%. The warm temperatures, low humidity and dry surface conditions will overlap with areas of dry fuels with ERCs above the 90th percentile. This will likely support several hours of Elevated fire-weather conditions, along with some locally critical conditions possible. ...Southern Plains... Farther south, broad southerly flow is likely along the lee trough over parts of eastern CO, western KS and the OK/TX Panhandles as the surface low strengthens. While fuels here are not as receptive, some drying and periods of moderately low RH will overlap with areas of gusty winds around 15-20 mph. This could support some localized fire-weather concerns as fuels continue to dry. ...Please see www.spc.noaa.gov/fire for graphic product... $$
