Day 2 Fire Weather Outlook

Valid 301200Z - 311200Z

Trimmed the eastern edge of the IsoDryT area across central/southern
Oregon. Thunderstorm activity is not expected to make it far off the
terrain amid weak steering flow. Otherwise no changes were
necessary. See previous discussion below.

.PREV DISCUSSION... /ISSUED 0200 AM CDT Fri Jul 29 2022/

...Synopsis...
A midlevel low will approach the northwestern CONUS from the
northeastern Pacific, with increasing cyclonic flow overspreading
parts of the Pacific Northwest. The increasing south-southwesterly
flow and modest midlevel ascent ahead of this feature should support
isolated high-based thunderstorms along the Cascades in northern CA
into central OR from the afternoon into the evening hours. While
these storms may be a mixed wet-dry mode (0.75-1.0 in PW), isolated
lightning-induced ignitions will still be possible away from any
precipitation cores.

Additionally, widespread 10-15 percent minimum RH is expected from
the Cascades eastward into the northern Rockies during the
afternoon. While sustained surface winds should generally remain
below 15 mph across the area, locally elevated conditions will still
be possible over terrain-favored areas given the presence of
critically dry fuels.
