.DISCUSSION...
We are currently in a lull this afternoon before the rain we are
expecting late tonight into tomorrow. We have a trough off the
coast along with very high probabilities of Integrated Water
Vapor Transport values of at least 250 kg/(m*s). This high IVT
values brings a strong 60 to 95 percent probability of an inch
or more of rain in the San Joaquin Valley by Wednesday morning.

The high moisture value also brings high probabilities of heavy
snow with a 30 to 50 percent probability of 18 inches or more of
snow at 7,000 feet. There is a 50 percent chance of at least 24
inches of snow or more total above 8,000 feet. These high
values have resulted in a continuation of the Winter Storm
Warning through Wednesday afternoon. The highest probabilities
will be in Fresno County and northward. However, Tejon and
Tehachapi Passes will not see any snow due to the very warm
nature of this storm.

Model ensembles are showing the trough to exit California on
Tuesday night into Wednesday morning. Ensembles are in agreement
that a rex block off the coast will be established on Thursday
leading to continuing spotty showers through Friday. However,
the pattern changes as the rex block turns into a ridge. Latest
CPC 6-10 and 8-14 day outlooks have a 40 to 60 percent chance of
below average precipitation and increasing probabilities of
above average temperatures.
