Day 2 Fire Weather Outlook
NWS Storm Prediction Center Norman OK
1216 AM CDT Mon Sep 01 2025

Valid 021200Z - 031200Z

...Synopsis...
The primary fire weather concern for Tuesday will be the potential
for isolated dry thunderstorms across portions of northern CA into
portions of northwest NV and central OR. Recent water-vapor imagery
depicts a weak upper low off the southern CA coast that is forecast
to meander northward over the next 48 hours. As this occurs, lift
and mid-level moistening ahead of the wave will promote sufficient
destabilization for convection beginning as early as 12z Tuesday
morning across central CA, spreading northward through the afternoon
and evening. In general, mid-level moisture quality should decrease
with northward extent on the fringes of the better monsoonal
moisture. An ensemble of forecast soundings suggests PWAT values may
range from 0.6 to 0.8 inches across northern CA/northwest NV/central
OR, which should favor a mix of wet and dry thunderstorms. Forecast
storm motions between 15-20 knots may also help promote isolated dry
lightning strikes over a landscape with ERCs between the 80th to
95th percentiles.
