Day 2 Fire Weather Outlook
NWS Storm Prediction Center Norman OK
1056 AM CST Fri Nov 17 2017
Valid 181200Z - 191200Z
...Mountains and Foothills of Southern CA...
A few hours of elevated fire weather conditions are anticipated
across the region early Saturday morning, primarily across the
mountains of Santa Barbara, Ventura, and Los Angeles counties.
Offshore gradient will decrease diurnally before increasing again
Saturday night/Sunday morning. Winds are expected to be slightly
weaker Saturday night/Sunday morning than Saturday morning but poor
overnight recovery will likely still result in elevated fire weather
conditions over the mountains and foothills of Santa Barbara,
Ventura, and Los Angeles counties.

Northerly surface winds will be ongoing across southern California
at the start of the forecast period. These winds will act to help
dry out fine fuels across the area. By mid-to-late morning, the
Santa Ana winds are anticipated to weaken, ending this low-end
elevated fire-weather threat.
Overnight Saturday into Sunday, northerly surface winds are expected
to develop once again. These winds will usher in a cooler/drier
airmass. By afternoon, minimum relative humidity will fall to the
5-15 percent range; however, surface winds will be decreasing by
this time. Because the strongest surface winds and lowest
relative-humidity values will be out of phase, critical fire-weather
conditions do not appear likely. Thus, elevated fire-weather
highlights will be introduced.
