Day 1 Fire Weather Outlook
NWS Storm Prediction Center Norman OK
1128 AM CDT Sun Aug 21 2022
Valid 211700Z - 221200Z
There are no changes to the outlook. In addition to the fire-weather
concerns described below, scattered diurnally driven thunderstorms
are expected over the northern Rockies this afternoon into the
evening where fuels are critically dry. While isolated ignitions
will be possible away from the heavier precipitation, 0.75-1.0+ inch
PW (sampled by regional 12z soundings/GOES-16 derived PW) and slow
storm motions will favor a mixed wet-dry to wet storm mode --
precluding Dry Thunderstorm highlights.

...Synopsis...
Upper ridging will be in place across the western U.S. as broad
cyclonic flow aloft envelops the eastern two-thirds of the CONUS
today. By evening, a pronounced mid-level trough will impinge on the
Pacific Northwest and lift a monsoonal airmass across Oregon,
fostering isolated high-based thunderstorm development. While some
of the storms will be slow moving, enough potential exists for
strikes to occur away from storm cores into dry fuel beds,
warranting the continuation of isolated dry thunderstorm highlights.
