Day 1 Fire Weather Outlook 
NWS Storm Prediction Center Norman OK
1018 AM CDT Fri Jun 17 2022

Valid 171700Z - 181200Z

...CRITICAL FIRE WEATHER AREA FOR EASTERN NEVADA...WESTERN
UTAH...AND NORTHWEST ARIZONA...

The forecast remains on track with only minor adjustments needed
based on morning observations and trends in latest guidance. Very
dry conditions were analyzed over southern NV into southwest UT this
morning, and regional VWPs have sampled very strong (40-65 mph)
winds within the lowest 1-2 km. These winds are already beginning to
mix to the surface where temperatures have warmed into the low 80s,
and will beco*e more widespread through the late morning and early
afternoon hours. These observations maintain high confidence in
widespread critical fire weather conditions today with the potential
for periods of extremely critical conditions along the NV/UT border.
Other forecast concerns remain on track as outlined in the previous
discussion below.

.PREV DISCUSSION... /ISSUED 0150 AM CDT Fri Jun 17 2022/

...Synopsis...
The upper-level trough along the West Coast will progress into the
Great Basin today. Strong mid-level winds will overspread the region
in conjunction with a surface trough deepening within the Basin into
the northern Rockies. To the east, an upper-level ridge will remain
across the Plains. Mid-level moisture will push westward and a
modest lee trough will develop in the central/northern High Plains.

...Great Basin...
Very strong surface winds of 25-35 mph, primarily in Nevada/Utah,
are expected to develop within the region by afternoon. Regional
soundings from Thursday night show single digit RH and this can be
expected to continue today. Areas of extremely critical fire weather
are possible given these meteorological conditions. Fuel sparseness
where these conditions are expected may limit a greater fire weather
risk. Mid/upper-level clouds will also be on the increase during the
day, particularly in the westernmost areas.

Isolated dry thunderstorms are possible along the western periphery
of the mid-level moisture. Areas most likely to be affected are from
the Four Corners into southwestern Wyoming.

...Central High Plains...
Elevated to near-critical fire weather is expected for parts of the
region. Afternoon RH will fall to 15-20% with the lee trough
promoting 15-20 mph winds.
