Day 1 Fire Weather Outlook  
NWS Storm Prediction Center Norman OK
1247 AM CST Thu Nov 07 2024

Valid 071200Z - 081200Z

...CRITICAL FIRE WEATHER AREA FOR PORTIONS OF VENTURA AND LOS
ANGELES COUNTIES IN SOUTHERN CALIFORNIA...

...Synopsis...
A highly amplified large-scale ridge will remain in place across the
West Coast, while a deep midlevel low moves slowly eastward over the
Southwest. Between these two features, a belt of strong deep-layer
northerly flow will continue to overspread the Lower CO River Valley
and southern CA. This large-scale pattern will maintain surface
ridging over the Intermountain West/Great Basin, and an associated
tight offshore pressure gradient across southern CA. 

...Southern California...
From Thursday morning through the afternoon, the LAX-DAG gradient
should remain around -4 to -5 mb -- indicating moderate to strong
Santa Ana winds across southern CA. This offshore pressure gradient,
co*bined with the northerly upper-level wind support, will favor
sustained northeasterly surface winds of 20+ mph (with higher gusts)
amid lower teens to single-digit RH across portions of southern CA.
Over the wind-prone corridor of northern Los Angeles into southern
Ventura Counties, several hours of 40-50-mph gusts and single-digit
RH will lead to critical fire-weather conditions -- further
exacerbating a large ongoing wildfire incident in Ventura County. 

The pressure gradient will gradually weaken into the evening hours,
with a corresponding decrease in surface winds. However, dry
boundary-layer conditions/poor overnight recoveries are expected
into Day 2/Friday.
