.KEY MESSAGES...
1. Drier air will cause minimum relative humidity to fall
between 10 and 20 percent for much of the region through the
forecast period. There is Moderate Fire Risk as a result.

2. Temperatures are expected near normal for much of the area
with Minor Heat Risk in the San Joaquin Valley and Moderate Heat
Risk in the Kern County Desert.

3. Stronger wind gusts are possible in the Mojave Desert Slopes
later this evening with a 40 to 70 percent chance to exceed 40
mph.

&&

.DISCUSSION...
An incoming upper level trough is causing winds aloft to shift
towards the southwest, resulting in a slight cooling trend with
temperatures today expected within a few degrees of season
averages. While this pattern will continue through early next
week, winds are expected to decrease slightly tomorrow, causing
a one-day warming trend with temperatures one to three degrees
warmer than today. There is a 20 to 70 percent chance for
triple-digit temperatures to return next Wednesday and Thursday
for the San Joaquin Valley as high pressure builds in; the
greatest chances will be in the southern valley and in the
larger urban areas. Valley winds will largely be from the
northwest due to the temperature disparity.

Ensemble guidance continues to hint at another trough
approaching the Pacific coast late this week into next weekend.
If this holds, conditions will be very similar to those seen
this weekend.

.AVIATION...
18Z Update:

VFR conditions will prevail for the next 24 hours across the Central
California Interior.

&&

.FIRE WEATHER...
While conditions are generally cooler than earlier this week,
dew point temperatures are also lower, resulting in widespread
relative humidity values in the 10 to 20 percent range. As we
have seen in previous days, hundred to thousand acre grass fires
have sprung up as a result of these low RH values and stronger
late afternoon winds. These values will continue well into next
week, continuing an elevated risk for fire development.
