Day 1 Fire Weather Outlook
NWS Storm Prediction Center Norman OK
1129 AM CDT Sat Sep 05 2026

Valid 051700Z - 061200Z

...NO CRITICAL AREAS...

As an upper low remains anchored over the Pacific Northwest, strong
southwesterly flow atop the Great Basin will continue to enhance a
very dry boundary layer amid breezy sustained southerly winds of
20-25 mph (gusts up to 35 mph or greater) this afternoon.
Meteorological conditions would otherwise support an elevated (or
perhaps critical) fire weather threat in southern Nevada and western
Utah, but a marginal fuelscape averts any risk areas. Please see the
previous discussion for more details.

.PREV DISCUSSION... /ISSUED 1251 AM CDT Sat Sep 05 2026/

...Synopsis...
Similar to Friday, upper-level troughing will persist across the
Pacific Northwest and Northeast, with upper level ridging also
remaining centered over the southern Great Plains. Modestly strong
southwestern flow will continue across much of the Great Basin,
northern Rockies, and northern High Plains. This troughing pattern
and attendant precipitation, cloud cover, and cooler temperatures
will continue to largely limit fire weather concerns across the
western U.S. today. Elsewhere, a surface frontal system will
continue to bring chances for rain to portions of the Midwest/East
Coast.

...Central/Northern Wyoming...
While less widespread compared to Friday, sustained southwesterly
winds of 10-20 mph and RH values of 15-20% (locally down to 10%) may
overlap areas of receptive fuels across portions of central and
northern Wyoming this afternoon. These conditions may support
locally elevated fire weather concerns; however, the duration and
spatial extent of wind/RH overlap are forecast to remain relatively
limited. Thus, Elevated highlights have been withheld.

...Great Basin...
Southwesterly flow of 15-25 mph amid minimum RH values of 10-20%
will continue across the eastern/southern portions of the Great
Basin today. Locally elevated fire weather conditions may develop
where recent rainfall was minimal and/or where pockets of dry fuels
remain. Generally marginal fuels across this region are expected to
preclude a broader fire weather risk, however.
