...ELEVATED FIRE WEATHER THREAT CONTINUES THROUGH THE WEEKEND DUE
TO HOT AND DRY CONDITIONS AND AFTERNOON WINDS...
.DISCUSSION...Hot and dry conditions persist through Saturday
across the interior due to high pressure over the region. Breezy
onshore winds develop each afternoon and evening with gusts
reaching 20 to 25 mph through favored gaps, passes, valleys, and
coastlines. The marine layer influence will bring good to moderate
overnight humidity recoveries in the lower elevations, but the
hills and thermal belts remain mild and dry overnight. Monsoonal
moisture from the south continues to present a very low, but non-
zero, chance for elevated convection through Saturday. A gradual
cooling and moistening trend begins Sunday and extends through
next week.
Note : All winds are 20-foot Winds Unless otherwise specified.
Thunderstorms imply strong, gusty and erratic winds.
