   ...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.

   ...Synopsis...
   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.
