...CRITICAL FIRE WEATHER AREA FOR NORTHWEST GREAT BASIN AND SOUTHERN
IDAHO INTO SOUTHWEST MONTANA...
...CRITICAL FIRE WEATHER AREA FOR NORTHEAST UTAH AND
SOUTHERN/CENTRAL WYOMING...
The overall forecast for widespread elevated to critical conditions
across the northern Intermountain West onto the northern Plains
ahead of an approaching cold front remains on track. However, based
on the latest observations and high-resolution guidance, the
Elevated area was expanded south/east in portions of Nevada, Utah,
and Colorado. Additionally, both Critical areas were expanded.
Elevated/locally critical conditions will continue overnight from
southeast Montana through eastern Wyoming. Elevated conditions are
likely to linger into the overnight in portions of the Great Basin,
especially at mid/upper slopes due to remaining in the pre-frontal
environment, with poor RH recovery and gusty winds aloft.

...Synopsis...
A mid-level trough will rapidly traverse the northwestern CONUS
while supporting the development of a pronounced surface cyclone
across southern Saskatchewan today. As the surface cyclone quickly
translates eastward through the period, a wide corridor of strong
surface gradient winds will overlap with a dry boundary layer and
overspread very dry fuels across portions of the northwestern to
north-central U.S. Elevated highlights are in place across the Great
Basin toward the Northern Plains. Widespread 15 mph sustained
westerly surface winds are expected from eastern Oregon to central
Wyoming, with the wind direction shifting to more southerly across
the Plains states (given surface lee troughing). RH will drop to 15
percent over portions of the Intermountain West, with RH dipping to
20-25 percent in the Northern Plains. Sustained surface wind speeds
are expected to reach 20-25 mph over portions of the Harney Basin
into the northern Great Basin, as well as central Wyoming by
afternoon peak heating, where Critical highlights have been
introduced.
