Day 1 Fire Weather Outlook
NWS Storm Prediction Center Norman OK
1141 AM CDT Thu Jun 23 2022
Valid 231700Z - 241200Z
The previous forecast remains valid with minor adjustments.
Scattered storm coverage expected later today should remain mostly
wet with PWATs climbing into the 0.75 to 0.9 inch range across
southern NV. Isolated dry storms and CG strikes should remain
possible within the DRYT area across central NV and far western UT
outside of the heavier precip cores. Here, fuels remain more
receptive to ignitions. Please see the prior discussion for more
information.

...Synopsis...
The weak cutoff low currently over the central California coast will
slowly progress northeastward overnight Wednesday into this morning.
This low is expected to phase with the broader cyclonic flow over
the Northwest and accelerate through Nevada and Utah by Friday
morning.
Fire weather concerns will be focused within the western and central
Great Basin today. Isolated to scattered thunderstorms are possible.
The greatest storm coverage is expected to be across east-central
Nevada into far west-central Utah. GPS PWAT retrievals show a sharp
gradient moving northward through the lower Colorado River Valley.
By afternoon, PWAT values in the 0.5-0.75 inch range across most of
central Nevada. Slower storm motions along/near the Sierra should
help produce greater wetting rainfall. To the east of the subtle
trough enhanced mid-level winds will lead to greater potential for
dry thunderstorms. There is still enough uncertainty in greater
coverage of dry thunderstorms to withhold scattered dry thunderstorm
highlights.
