Day 1 Fire Weather Outlook

...CRITICAL FIRE WEATHER AREA FOR NORTH-CENTRAL MONTANA...

...Synopsis...
A midlevel shortwave trough is forecast to move eastward across the
northern Rockies today. Strong west-southwesterly flow aloft
associated with this feature will overspread the Pacific Northwest
and northern Idaho/Montana.  In response at the surface, low
pressure will deepen over Alberta and Saskatchewan.

...Northern Rockies and adjacent High Plains...
Along the southern periphery of the surface low, a swath of 20-25
mph sustained westerly surface winds are expected across parts of
north-central MT. These strong winds, coupled with a
hot/deeply-mixed boundary layer (10-15 percent minimum RH) will lead
to critical fire-weather conditions. In addition, mixed wet-dry
thunderstorms should spread eastward across the northern Rockies,
acco*panied by locally strong outflow winds. Given the expected high
cloud bases and relatively fast storm motions (over 30 mph), limited
rainfall accumulation is expected, supporting isolated dry
thunderstorm potential.

...Pacific Northwest...
Deep boundary-layer mixing in the presence of strong westerly flow
aloft co*bined with downslope warming/drying in the lee of the
Cascades will result in 15-20 mph sustained westerly surface winds
and 15-20 percent RH. Given receptive fuels from WA into OR,
elevated to locally critical conditions can be expected.
