.KEY MESSAGES...
1. Dense Fog Advisory issued for the San Joaquin Valley valid
from 12AM Tuesday morning through 1 PM Thursday due to
persistent chances for fog each night and morning through that
timeframe.

2. Temperatures near to just below season averages through the
week. Low probability for freezing temperatures in the Mojave
Desert for much of the week, high probability for the Sierra
Nevada.

3. Indications for a low pressure system over the western US to
end the month, though uncertainty remains for exact location and
impacts for central California.

.DISCUSSION...
The stratus hung around on Monday leading to temperatures to
hover at or below 50 degrees. However, visibilities have not
been able to get down to a quarter mile this morning as easily
due to the overcast skies. Latest ensembles have the clouds
lifting a little bit but ceilings are expected to remain below
1000 feet. The NBM has at least 90 percent chance of highs
climbing to at least 55 degrees today.

This cloudy and foggy pattern is thanks due to a ridge of high
pressure that is strengthening off the coast. However, the setup
has cold air flowing over the area along with the subsidence
which favors the stratus and fog from not lifting or dissipating
as quickly. The latest ensembles have a trough sliding in late
Friday into the weekend bringing a change with cooler
temperatures. However, despite lowering snow levels, this system
looks to be drier as the upper level flows will be more from
interior British Columbia and not the Gulf of Alaska. There is a
25 percent chance or less of 6 inches of snow with this system
above 6,000 feet along with a 20 percent chance of an inch of
snow over Tehachapi.

.AVIATION...
IFR ceilings are expected to persist throughout the Valley
through at least 18Z Tuesday, with visibilities mostly in IFR

18Z, the ceilings would improve to IFR to MVFR with visibilities
in MVFR until about 06Z Wednesdays before falling back to IFR to
lIFR.
