A deepening mid to upper-level trough and accompanying jet streak are expected to traverse the western Canadian provinces Sunday. At the surface, a low will deepen across the northern Rockies and tightening pressure gradients will develop from the northern Plains, into the Intermountain West, and Cascades. The result will be increasing surface winds within these areas. A dry return-flow regime over the northern Plains will unfold, where high confidence in the latest guidance suggests speeds around 15-25 mph by the afternoon. Persistent low moisture content of fine to medium fuels across this region, ERCs exceeding 95th percentiles, and RH in the low teens warrants a narrow Critical area from the NE Panhandle through west-central SD. Further west of this region, southwest to westerly winds of slightly lower speeds will impact central WY, southern MT, and portions of ID. Two other Elevated areas have also been included for the Great Basin and Columbia River Basin of WA. Fuels across the former region continue to become more receptive to fire spread due to persistent warm and dry conditions, but only transient elevated to critical south-southwest winds are anticipated. Dry, westerly downslope surface flow near 15 mph coinciding with RH in the upper teens preceding the trough will impact eastern WA. If later guidance suggest a deeper and/or slower trough progression, this Elevated area may need to be expanded. ..Barnes.. 09/28/2024 ...Please see www.spc.noaa.gov/fire for graphic product...
