Day 2 Fire Weather Outlook
NWS Storm Prediction Center Norman OK
0258 PM CDT Mon Jul 07 2025

Valid 081200Z - 091200Z

...Northwest and Great Basin...
An approaching mid-level trough and associated increasing mid-level
west winds will introduce elevated fire weather conditions into the
Columbia Gorge/Basin and adjacent leeward slopes of the Cascades
Tuesday. A mid-level low off the coast of northern CA will provide
supportive dynamics for isolated thunderstorms across central OR.
Limited precipitation with these thunderstorms will increase fire
ignition potential amid receptive fuels primarily across the higher
terrain of central and east-central OR. Elevated fire weather
conditions atop dry fuels are still expected across much of central
and eastern NV and far western UT where southwest winds of 10-20 mph
and relative humidity in the 10-15% range will be collocated.

...Synopsis...
A midlevel low will gradually approach the northern CA coast as it
loosely phases with a stronger midlevel trough moving eastward
across British Columbia on Tuesday. Large-scale ascent preceding the
midlevel low will aid in isolated thunderstorm development along the
higher terrain of central OR. Around 0.7 inch PW and a deeply mixed
boundary layer will favor dry thunderstorms, with an associated risk
of lightning-induced ignitions and strong/erratic outflow winds. At
the same time, a belt of moderate-strong midlevel winds peripheral
to the trough in British Columbia will cross the Cascades. This will
promote dry/breezy downslope winds in the Columbia Basin, with the
strongest winds expected through the Cascade Gaps. Given
dry/receptive fuels, elevated fire-weather conditions are expected.

Farther south, moderate deep-layer southwesterly flow ahead of the
midlevel low will overspread a well-mixed boundary layer across
parts of central/southern NV, where elevated to locally critical
fire-weather conditions are expected.
