Day 1 Fire Weather Outlook 
NWS Storm Prediction Center Norman OK
1059 AM CST Tue Nov 05 2024

Valid 051700Z - 061200Z

...17z Update...
Minimal changes have been made to the Elevated area over northern
CA. Slightly stronger winds and lower humidity may occur over the
higher peaks of the coastal ranges this afternoon and evening. Gusty
winds and lower humidity may also extend farther south down the
Central Valley. This could support elevated fire-weather conditions
for a few hours. The elevated area was shifted slightly south.

Across southern CA, offshore pressure gradients should increase
overnight Tue into early Wed. Below 15% humidity and winds greater
than 20 mph are possible over the Transverse and Peninsular Ranges
and sustained Elevated conditions potentially beginning prior to 12z
Wed. Thus, have added an Elevated area to better account for the
increasing fire-weather threat into early Wed morning. Otherwise,
see the previous outlook for more info.

.PREV DISCUSSION... /ISSUED 0208 AM CST Tue Nov 05 2024/

...Synopsis...
On the backside of a broad/amplified large-scale trough centered
overt the Rockies, a belt of strong deep-layer northerly flow will
overspread CA. At the same time, the surface pressure gradient will
tighten over northern/central CA -- along the southern periphery of
strengthening surface ridging over the Northwest. This will yield
15-20 mph sustained northerly surface winds (with higher gusts) over
portions of the western Sacramento Valley into the Coastal Range.
These strong/gusty winds, coupled with 15-20 percent afternoon RH,
will favor elevated to locally critical fire-weather conditions.
