...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.
