Day 2 Fire Weather Outlook

...Synopsis...
Broad troughing over the western US will continue as a compact
shortwave trough moves across northern CA Thursday. 40-50 kt
westerly flow will overspread the northern Great Basin. This will
encourage dry downslope flow across parts of western NV. At the same
time, continued monsoon moisture will allow widespread showers and
thunderstorms over the Intermountain West.

...Northwest Great Basin...
Continued westerly flow aloft will overspread the northern Great
Basin Thursday afternoon. Dry downslope winds of 15-25 mph are
expected, aided by the increasing winds aloft. Very warm
temperatures, and the dry downslope trajectories, will support
widespread RH values below 15%. The increase in surface winds amid a
warm and dry boundary layer and dry fuels will support elevated
wildfire spread potential Thursday.

...Western Slope...
Another day of widespread showers and thunderstorms is expected
across the eastern Great Basin and western Rockies Thursday. A
continued surge of robust monsoon moisture (PWATS above 0.8 inches)
will support a mixed mode of wet and occasionally dry storms.
Widespread QPF of 0.1-0.25 inches in the preceding days suggest area
fuels are likely to become less receptive to lightning ignitions
with time. However, the coverage of storms does support at least
isolated potential for dry strikes in receptive fuels across western
CO/WY into eastern UT.
