As ridging builds over the Pacific Northwest, broad upper-level troughing will extend across the Upper Midwest and Great Lakes regions. A shortwave trough will move into the northern Rockies Friday afternoon with increasing mid-level westerly flow ushering low RH and gusty winds through the Snake River Plain. Enhanced zonal flow over the CO Rockies and south-central WY will promote gusty winds and downslope drying amid warm daytime temperatures, continuing a broader fire weather threat where fuels approach critical thresholds. ...Upper Colorado River Basin, Central Rockies, and southern Wyoming... Strong upper-level winds will overspread the region on Friday afternoon, encouraging continued dry and breezy conditions while surface temperatures rise 10+ degrees above normal under the influence of high pressure. Sustained westerly winds of up to 15 mph and 10-15% RH are expected to overlap a drying fuelscape, thus Elevated highlights have been introduced. Localized critical conditions (less than 10% RH and 15-20 mph winds) are possible across portions of northeastern UT and southern WY. However, sparse fuels preclude critical highlights, though an upgrade may be considered in future outlook cycles. ...Snake River Plain... Ahead of an approaching cold front, sustained westerly winds of 10-20 mph will combine with 10-15% RH (locally lower) in the Snake River Plain, supportive of Elevated highlights. Weeks of dry, windy conditions and minimal precipitation has inflicted curing of fuels across the region, enhancing fire weather concerns as ERCs approach the 80th-90th percentile on Friday. ..Elizalde-Garcia.. 06/11/2026 ...Please see www.spc.noaa.gov/fire for graphic product... $$
