2. Maximum temperatures today are expected to be around three to
six degrees below seasonal averages.

3. Dry and warming conditions next week, with highs around
eight to twelve degrees above normal by Friday.

.DISCUSSION...
The low pressure system which brought some showers and
thunderstorms to central California, along with areas of
mountain snow and some strong wind gusts, is currently swinging
eastward away from our area. Skies have generally cleared, with
just some upslope cloudiness lingering in Kern and Tulare
counties.

We will see weak ridging overhead today as the low pressure
system continues to amble eastward. This will lead to generally
dry conditions with temperatures warming to just a couple of
degrees below normal. A few residual Sierra showers are
conceivable, but blended model guidance keeps probabilities at
15 percent or less.

Ensemble model solutions slide another developing low pressure
system from near the Gulf of Alaska inland across the
northwestern United States through the early part of next
week. During this period, we will be under a broad cyclonic flow
with continued dry conditions and temperatures rising to around
2 to 4 degrees above normal. Temperatures will then trend
further upward through the end of the week, and by Friday,
afternoon highs are progged to be around 8 to 12 degrees above
normal. Probabilistic guidance is around 30 to 50 percent for
high temperatures of at least 87 degrees in the San Joaquin
Valley next Friday.

This synoptic pattern will also bring periods of moderate gusty
northwesterly winds. Probabilistic guidance shows at least 85
percent probabilities for wind gusts of 45 mph or higher along
the Mojave Desert Slopes this evening and overnight. A Wind
Advisory has been issued for there from 6 PM this evening
through 3 AM Sunday morning.
