Day 1 Fire Weather Outlook  
NWS Storm Prediction Center Norman OK
1109 AM CDT Fri Aug 02 2024

Valid 021700Z - 031200Z

Latest guidance suggests reduced low-level moisture into portions of
central/northern Oregon and Washington this afternoon as strong
heating/mixing co*mences, limiting the amount of instability for
thunderstorm potential this afternoon/evening. Perhaps an isolated
storm or two may occur, but the expected sparse coverage has led to
a removal of the isolated dry thunderstorm delineation for this
region.

Farther south, isolated dry thunder potential has been extended
across parts of central/northern California. In general, a wave of
convection is expected to traverse this region from south to north
throughout the day. A transition from dry to wet storms is expected
with a continued southerly influx of subtropical moisture into the
region, though progressive storm motions, outflow gusts, and
receptive fuels should promote large-fire spread with any of this
activity.

...Synopsis...
A midlevel disturbance will move across southern California into
Oregon through the D1 period. Preceding this feature, a plume of
sufficient midlevel moisture, atop a diurnally deepening boundary
layer, will be in place. Increasing moisture, in co*bination with
forcing from the midlevel disturbance, will support isolated to
widely scattered high-based thunderstorms across the high terrain of
California into portions of central Oregon and western Washington.
