Day 2 Fire Weather Outlook
NWS Storm Prediction Center Norman OK
0153 AM CDT Tue Jul 08 2025

Valid 091200Z - 101200Z

...Synopsis...
A compact midlevel trough will track eastward across the Northwest
during the day -- in tandem with a robust midlevel trough/low moving
eastward from British Columbia into Alberta. Large-scale ascent
preceding the midlevel trough moving across the Northwest will
promote another day of isolated high-based thunderstorms -- with a
focus over southeastern OR into southwestern ID. Deep inverted-V
soundings and PW around 0.7 inches will favor dry thunderstorms
capable of producing lightning-induced ignitions and strong/erratic
outflow winds.

Similar to Day 1/Tuesday, a belt of strong deep-layer westerly flow
(peripheral to the midlevel trough) across the Cascades will lead to
breezy/gusty westerly surface winds in the Columbia Basin. While
increasing boundary-layer moisture will limit RH reductions compared
to Day 1/Tuesday, stronger surface winds will offset this and still
yield elevated fire-weather conditions.

Over the Great Basin, moderate midlevel southwesterly winds
accompanying the compact midlevel trough will overspread the Great
Basin during the day. Deep boundary-layer mixing into this
strengthening flow aloft will support another day of elevated to
locally critical fire-weather conditions, given increasingly
dry/receptive fuels.
