Day 1 Fire Weather Outlook  
NWS Storm Prediction Center Norman OK
1236 AM CDT Mon Aug 03 2020

Valid 031200Z - 041200Z

...Synopsis...
An upper-level trough will move into the northern Rockies today.
Modest to moderate mid-level flow will extend from the
central/northern Great Basin into Idaho. At the surface, a cold
front will progress eastward into the northern Rockies with pendant
surface trough extending through western Utah into southern Nevada.
As mid/high level clouds clear, boundary-layer mixing and an
enhanced surface pressure gradient near the front will promote 15-20
mph with localized higher speeds. RH is expected to fall to 15-20%.
Elevated conditions are also possible within southwest Wyoming and
adjacent portions of the Wasatch and Uintas. Similar wind and RH
combinations can be expected. There is some possibility that
mid/high clouds will linger longer into the afternoon. This could
reduce fire risk in some locations. Locally elevated conditions are
possible near the surface trough into southern Utah, though weaker
mid-level winds should keep the duration and spatial extent low.
Potential for dry thunderstorms in northwestern Colorado and
adjacent southern Wyoming still appears too low to introduce
highlights.

Day 2 Fire Weather Outlook  
NWS Storm Prediction Center Norman OK
0206 AM CDT Mon Aug 03 2020

Valid 041200Z - 051200Z

...Synopsis...
As a shortwave trough passes into the northern Plains, another weak
shortwave trough will approach the central California coast on
D2/Tuesday. A frontal boundary will remain in place across southern
Idaho into central Wyoming. Strong surface heating will again take
place within the Great Basin.

With similar mid-level winds to Monday, dry/breezy conditions are
possible across southwestern Wyoming. Winds of 15-20 mph will
coincide with 10-20% RH during the afternoon. The overall fire
threat will be limited by sparse fuels. Furthermore, some guidance
suggests that thunderstorms may occur within the Uintas and limit
the duration of elevated conditions. Even so, this would bring some
concern for lightning ignitions should this occur.

Within southern Nevada, mid-level flow will remain modest even with
the approach to of the trough to the west. Strong surface heating
may help increase winds to 15 mph with RH falling to 5-15%. These
conditions will be fairly typical for this area. Fuels are somewhat
drier for this time of year given the lack of monsoon impacts thus
far.
