The upper trough over the Northwest is forecast to remain mostly stationary as the adjacent ridge over the Rockies begins to weaken and shift to the east. Stronger flow aloft will gradually overspread the Northwest and northern Rockies through the week. Isolated dry thunderstorms and gusty downslope winds will promote elevated fire-weather potential D2/Tuesday. ...Northwest and Northern Rockies... With the upper trough over the Northwest expected to remain fairly stationary, lingering mid-level moisture and weak ascent will continue to support mid-level destabilization and thunderstorms D2/Tuesday afternoon. Very warm surface temperatures and fast storm speeds will again favor mostly dry storms with the potential for lightning ignitions in dry fuels. Forcing for ascent should be slightly less than previous days, casting some uncertainty on storm coverage. However, at least isolated dry thunderstorms are possible over parts of eastern WA/OR and into western ID. West/southwest flow aloft is forecast to increase over the northern Rockies and Cascade Gaps ahead of the trough. This may promote several hours of gusty downslope winds across parts of eastern ID and western MT. Model guidance shows surface winds of 15-25 mph overlapping with RH values below 20%. This, along with the increase in lightning, will support the potential for elevated fire-weather conditions D2/Tuesday afternoon. ..Lyons.. 07/22/2024 ...Please see www.spc.noaa.gov/fire for graphic product...
