Day 2 Fire Weather Outlook
NWS Storm Prediction Center Norman OK
0135 PM CDT Tue Sep 02 2025

Valid 031200Z - 041200Z

Latest guidance continues to show the potential for isolated to
widely scattered thunderstorms on Wednesday across northern CA into
OR and adjacent portions of far northwest NV as an upper wave
(currently along the central CA coast) lifts northward.
Thunderstorms may be ongoing at the start of the forecast period
before a second round develops by late afternoon. High-res guidance
hints at cloud cover during the day that may hinder diurnal heating
and destabilization to some degree, and PWAT values near 0.75 inches
may support swaths of wetting rainfall with the more intense
convection (as hinted by some CAM solutions). However, antecedent
dry conditions within the lowest 2-3 km AGL should modulate rainfall
totals to some degree, and will support the potential for dry
lightning strikes - especially with weaker, more isolated storms.
With dry fuels already in place and ongoing fires noted across the
region, the potential for dry-lightning/thunderstorm driven fire
concerns remains sufficiently high to maintain ongoing highlights
despite some forecast concerns.

...Synopsis...
As the upper-level low continues to shift northward through
D2/Wednesday, the isolated dry thunderstorms chances will continue
across northern California into central Oregon, southern Washington,
and western Idaho. Storm motions will decrease but coverage and
moisture may also decrease with more isolated lingering activity
expected. An isolated dry thunderstorm area was maintained with this
outlook to cover this potential.
