Day 1 Fire Weather Outlook 
NWS Storm Prediction Center Norman OK
1047 AM CDT Sat Aug 06 2022

Valid 061700Z - 071200Z

The previous forecast remains on track with only minor adjustments
made based on trends in latest guidance. Morning water-vapor imagery
reveals mid-level confluence zone along the CA/OR border that will
provide weak ascent today. The 12 UTC MFR sounding sampled favorable
buoyancy atop a somewhat dry boundary layer that should support a
wet/dry mix of thunderstorms this afternoon.

...Willamette Valley...
Dry conditions are expected this afternoon through the Willamette
Valley with RH values falling as low as 20%. Terrain-augmented winds
may reach near 15 mph and support areas of elevated conditions.
While noted, this potential remains too localized for a broader risk
area.

.PREV DISCUSSION... /ISSUED 1230 AM CDT Sat Aug 06 2022/

...Synopsis...
A mid-level short-wave trough will move across portions of the
northern CONUS, from the Pacific Northwest to the northern Plains.
Meanwhile, an upper-level ridge will remain quasi-stationary over
the central CONUS with weak mid- to upper-level flow prevailing in
most areas. At the surface, a cold front will enter portions of the
northern/central High Plains. Ahead of this front, breezy
southwesterly surface winds near 20 mph should develop during the
afternoon across most of western Kansas and vicinity. However, RH
values should generally remain above critical/elevated thresholds
amid fuels that appear generally non-receptive to large-fire spread.

...Southern Oregon...
An area delineating the potential for isolated dry thunderstorms has
been introduced for the region. A narrow zone of convection should
develop during the late afternoon hours amid dry/receptive fuels and
PWAT values remaining below 0.75 inches. The highlighted area has
been confined to portions of the region that received little
appreciable rainfall yesterday.
