Day 2 Fire Weather Outlook
NWS Storm Prediction Center Norman OK
0223 PM CDT Wed Jun 03 2026

Valid 041200Z - 051200Z

An area of Elevated fire weather conditions was introduced over
portions of the Intermountain West along/behind the anticipated
position of a cold front on Day 2/Thursday. Behind this dry front,
sustained westerly winds of 10-20 mph are expected through much of
the afternoon hours. Hot and very dry (5-15% minimum RHs) conditions
supportive of deep boundary layer mixing up to 450 mb will be in
place over much of the Southwest, Great Basin, and central Rocky
Mountain regions. While some fraction of green vegetation
sporadically exists over some of this region, this combination of
wind/RH amid receptive fuel conditions will support a limited fire
weather risk. Given the right alignment of wind, RH, and very dry
fuels possible within localized portions of the drawn area, critical
thresholds could be briefly achieved.

...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.
