Day 2 Fire Weather Outlook 
NWS Storm Prediction Center Norman OK
0127 PM CDT Sat Aug 20 2022

Valid 211200Z - 221200Z

The previous forecast remains on track, and no changes were made
with this update. In addition to the fire-weather concerns described
below, widely scattered, diurnally driven thunderstorms are expected
over the northern Rockies during the afternoon and early evening.
While 0.75-1.0 inch PW and slow storm motions should favor a mixed
wet-dry storm mode, isolated ignitions will still be possible away
from the heavier precipitation cores given receptive fuels over the
area.

.PREV DISCUSSION... /ISSUED 1218 AM CDT Sat Aug 20 2022/

...Synopsis...
A mid-upper-level trough will continue to move east slowly across
the Great Lakes and Ohio Valley and the western ridge will continue
to build north into southwest Canada and east into the northern
Great Plains. Similar to Day 1 (Saturday), much of the contiguous
United States will be seasonably cool, moist, or both.

Isolated dry thunderstorms will be possible late Sunday night into
Monday morning across portions of the Interior Pacific Northwest as
large-scale ascent increases along the northwest fringe of a North
American monsoon driven moist plume across the West. This increasing
large-scale ascent is in response to an approaching negatively
tilted, mid-upper-level trough. The exact location of greatest
lightning potential will likely evolve over the next few forecast
cycles as smaller-scale details regarding the juxtaposition of
moisture and ascent co*e into better focus.

Elsewhere, minimal large-scale fire weather concerns are
anticipated.
