Fire Weather Outlook
— Day 2
No Critical Areas
Synopsis
Ahead of an approaching deep upper low currently offshore the British Columbia Coast, zonal flow will overspread the Northwest through the Upper Midwest. Multiple embedded shortwave troughs within the downstream flow will encourage additional precipitation across portions of Minnesota and Wisconsin, bringing some relief to a recently receptive fuelscape. Upper ridging will continue to flatten over the Great Lakes region, steering surface high pressure atop the Southeast and initiating a gradual warming trend into the weekend.
A dry airmass will persist across the Great Basin into northern Arizona with RH values declining to less than 15%. Weaker deep layer flow should limit widespread elevated sustained wind speeds, precluding any highlights. However, localized fire weather concerns may emerge in terrain-favored areas where gusty winds and critically low RH coalesce atop drying fuels. While a broader elevated was not introduced, these conditions will likely serve as more of a curing event, leading to increased fire concerns this weekend as an upper trough traverses the Northwest.
