.DISCUSSION...
Breezy conditions continue today, especially through the wind-
prone locations of Kern County. A Wind Advisory will be in
effect starting at 4 PM this afternoon lasting through early
Wednesday morning when onshore gradients are forecast to weaken
slightly. There will also be warming temperatures associated
with the modest decline in winds. This is due to shortwave high
pressure aloft developing over the region Thursday and Friday.
Dry conditions with above average temperatures are forecast
through Friday. NBM probabilities are generally showing around
a 50% chance of most locations in the San Joaquin Valley seeing
highs of at least 85*F on Friday afternoon.

The pattern is forecast to change this weekend. Ensemble
guidance continues to show a trough of low pressure dropping
into California Saturday afternoon, bringing cooler and wet
conditions. Valley rain and mountain snow is forecast to
continue Saturday evening through Sunday afternoon. Snow levels
are projected to be around 8,000 feet at the start of the event
on Saturday before dropping to around 6,000 feet Sunday morning.
The upper low is forecast to begin exiting the region on Sunday
night/Monday morning. As the upper low exits, a revamp of
strong winds in the Kern Mountains and Desert is forecast on
Monday. A modest warming trend is forecast thereafter.

Strong wind gusts 40 kts to near 50 kts are possible along the
Mojave Desert Slopes from 23Z Tuesday thru 12Z Wednesday.
