Day 2 Fire Weather Outlook 
NWS Storm Prediction Center Norman OK
0144 AM CDT Sat Jul 16 2022

Valid 171200Z - 181200Z

...Synopsis...
On the periphery of the dominant mid-level anticyclone across the
Southwest, a Pacific trough will deepen as it moves inland over the
Northwest Coast Sunday. A cold front will move ashore supporting
showers and isolated thunderstorms across the Cascades. At the same
time, gusty westerly winds will develop through the higher terrain
into the northern Great Basin. A dry and warm airmass beneath the
upper ridge will support elevated to near-critical fire weather
conditions Sunday.

...Northern Great Basin/southern Cascades...
As the upper trough moves inland and deepens Sunday, mid-level flow
is forecast to accelerate across much of the southern Cascades and
northern Great Basin. Model guidance shows 20 mph sustained winds
are likely with locally higher gusts near and through the higher
terrain gaps across southeastern OR, into northern NV and
southwestern ID. Dry and warm conditions on the edge of the upper
ridge will support widespread surface humidity below 15%. The
overlap of gusty downslope winds and warm/dry surface conditions
should support several hours of elevated to locally critical fire
weather concerns, given dry area fuels.
