Day 1 Fire Weather Outlook 
NWS Storm Prediction Center Norman OK
1127 AM CDT Fri Sep 06 2024

Valid 061700Z - 071200Z

The dry thunderstorm area from the northern Sierra into the
Northwest was adjusted to account for the most recent guidance.
Thunderstorms also appear likely in parts of the southern Sierra,
but diminishing mid/upper-level winds should keep storm motions slow
and potential for greater wetting rainfall higher.

...Synopsis...
Mid-level ridging centered over the Great Basin is forecast to
slowly decay today as a weak upper trough approaches the Pacific
Coast. Ahead of the weak trough, a modest influx of mid-level
moisture and ascent will overspread the northern Sierra and southern
Cascades. Adequate buoyancy will develop with daytime heating
supporting isolated thunderstorms through the evening hours. Beneath
the advancing mid-level moisture, dry boundary-layer profiles and
storm motions of 20-25 kt will favor low to very low rainfall
efficiency with these storms. With thunderstorms expected atop areas
of receptive fuels, dry lightning appears probable.

Additionally, strengthening southwesterly mid-level flow should
enhance downslope winds and low relative humidity across northern CA
into northwest NV. Areas of brief elevated fire weather conditions
are possible, though the duration and coverage should remain
limited.
