...Synopsis...
Western US troughing will intensify and shift eastward Friday as
westerly flow aloft overspreads the Great Basin. Dry downslope winds
are expected over much of the West. Elevated to critical
fire-weather conditions are possible, along with a few thunderstorms
Friday.

...Great Basin and Northern Rockies...
Westerly flow aloft is forecast to increase as the shortwave trough
over the West moves eastward. Dry downslope flow and warm
temperatures are expected across much of NV into western UT Friday.
Widespread westerly winds of 15-20 mph are expected. The stronger
dry, southwest flow will advected drier air across the much of NV
and southwest UT, resulting in a deep, well mixed boundary layer and
low surface relative humidity. Dry and deep boundary layer will also
support RH below 15%. Widespread elevated and locally critical
conditions are likely. Especially across southern NV into southwest
UT, where winds may approach 25 mph sustained with RH below 15%.

Along the eastern periphery of the drier air, isolated showers and
thunderstorms are possible again. Recent rainfall has reduced fuel
receptiveness across much of the Western Slope and eastern Great
Basin. Some lightning may occur with a mix of wet and dry storms
from ID, into southern MT, WY, and northern CO. However, the mixed
fuels, and another potential round of wetting rainfall suggests the
threat for dry strikes over receptive fuels is low.
