Day 2 Fire Weather Outlook
NWS Storm Prediction Center Norman OK
1253 PM CDT Sat Jun 22 2024

Valid 231200Z - 241200Z

The previous forecast generally remains on track with some
adjustments needed based on recent trends in guidance. Confidence
remains fairly high in the potential for elevated fire weather
conditions Sunday afternoon across portions of the greater Pacific
Northwest region. Drier/windier solutions continue to hint at the
potential for areas of critical fire weather conditions -
specifically in the lee of the Warner Mountains along the OR/NV
border and within the Snake River Plain. However, ensemble guidance
suggests this potential may remain fairly localized. Elevated
conditions will likely materialize across parts of western WY as
well, but latest fuel guidance indicates fuels are only modestly
receptive over this region.

.PREV DISCUSSION... /ISSUED 0101 AM CDT Sat Jun 22 2024/

...Synopsis...
An upper-level trough will move through Washington during the
afternoon. A strong pressure gradient will develop as a surface low
deepens in the northern Rockies into Alberta/Saskatchewan.

...Northwest...
Strong westerly surface winds across the Cascades will promote
downslope drying into the Columbia Basin during the afternoon. Given
some push of marine air to the east, it is possible that RH will not
become overly low. However, generally dry fuels and 15-20 mph winds
will support an elevated fire weather risk.

...OR/CA/NV...
The surface pressure gradient and mid-level winds will be weaker
than farther north, but confidence in RH of 10-20% is much higher.
Winds could locally approach 20 mph, but will more broadly be around
15 mph. Locally elevated conditions are expected to the lee of the
southern Cascades and northern Sierra.

...Snake River Plain...
On the fringe of the strong mid-level winds, favorably oriented with
the Valley, winds of 15-25 mph appear possible. RH of 15-20% can be
expected during the afternoon. Though meteorological conditions
could become critical, fuels are not sufficiently dry to support
more than an elevated risk.
