.DISCUSSION...
More record temperatures were broken Thursday but many spots
backed off a degree or two from Wednesday`s record. Latest NBM
probabilities has Friday breaking more records with a 20 to 30
percent chance of 95 degrees or higher in the Valley.
Bakersfield has a 10 percent chance of the first triple digits
of the year. The Desert has a 60 to 80 percent chance of highs
of at least 95 degrees for Friday.

Temperatures back off on Saturday as the ridge moves east and
begins to flatten as the Valley has a 60 to 70 percent chance of
90 degrees or higher. Sunday sees the biggest drop off as the
flow becomes zonal and even a shortwave trough passes through
Southern California. There is a 65 to 75 percent chance of
highs of at least 85 degrees on Sunday. The workweek looks to
continue the warm trend as the ridge rebuilds with Monday
through Wednesday has a 25 to 50 percent chance of high
temperatures of 90 degrees before dropping to 20 to 30 percent
on Thursday. The CPC outlooks continue to have very strong

.AVIATION...
VFR conditions are expected for the next 24 hours.

&&

.FIRE WEATHER...
Warm air temperatures and steady dew point temperatures will
lead to a decrease in minimum relative humidities, especially
for the Mojave Desert, high Sierra, and Coastal Range. This will
coincide with a sharp decrease in 100- and 1000-hr dead fuel
moistures and an increase in ERC in these areas. Rapid curing of
fine fuels will bring about some risk for isolated grass fires.
However, live fuel moisture remains below critical thresholds
and significant wild fire potential remains at little or no
risk.

&&

.AIR QUALITY ISSUES...
None.



&&

.CERTAINTY...

The level of certainty for days 1 and 2 is high.
The level of certainty for days 3 through 7 is medium.
