...CRITICAL FIRE WEATHER AREA FOR NORTHEAST NEVADA...SNAKE RIVER
VALLEY...SOUTHERN WYOMING...NORTHEAST UTAH...NORTHWEST COLORADO...

...Synopsis...
A strong mid-level jet will push into the central Rockies today, on
the back side of a broad upper-level trough along the Canadian
border. At the surface, a cold front will move across the
Intermountain West. Boundary-layer mixing of stronger flow aloft
along with a more stout surface pressure gradient than recent days
will lead to critical fire weather conditions across portions of
both the northern Great Basin and central Rockies. Winds of 20-25
mph will be common across the highlighted critical area. Potential
for 25+ mph sustained winds, and higher gusts, will be maximized
underneath the mid-level jet core in the Snake River Valley and
southern Wyoming. Elevated conditions will occur surrounding the
critical area as winds in these locations will either be lighter
(15-20 mph) and/or fuels will be slightly less receptive to fire
spread. All areas that have been highlighted can expect 10-15% RH
during the afternoon. Only minor changes have been made from the
previous forecast on account of the latest guidance. The critical
area in northeast Nevada was expanded slightly westward and the
elevated area was expanded to include more of central Colorado.
