.DISCUSSION...Latest radar shows a band of light to moderate
precipitation in the SJ Valley from northern Kern County to
Merced County, as well as the Sierra Nevada and adjacent
foothills. Satellite loops at this time show the upper-level
trough and cold pool mainly off the coast of Central and
Northern CA. Most locations in the valley have received up to a
quarter inch of rain so far today. Expect another 0.10 to 0.25
inch in many locations in the Central Valley through this
evening, except for isolated heavier amounts where thunderstorms
may develop. As for the Sierra Nevada, amounts are mainly up to
0.50 inch of precipitation (liquid equivalent), while a few
locations have received over 0.75 inch. A slight chance of
thunderstorms is shown over the SJ Valley and much of our
forecast area. So far, snow levels are around 5,000 to 5,500
feet, though are expected to fall to around 4,000 feet by this
evening. Most of the snow will be over the Sierra with the
highest elevations seeing another several inches of new snow (60
to 90 percent chance of at least 6 inches), although a few
locations in Kern County could see an inch or two of snow
accumulations, but mainly above the passes towards the Tehachapi
Mountains where there is up to a 50 percent chance of two inches
of snow accumulations. There is a low chance (less than 15
percent) that the Grapevine could see a dusting near the Tejon
Pass summit by this evening.

Gusty winds will develop over the Kern County desert and Mojave
Desert slopes by this afternoon where a Wind Advisory and High
Wind Warning remain in effect. Latest guidance shows gusts over
60 mph at a 30-50 percent probability of occurrence over the
Mojave Desert slopes. Otherwise, more widespread gusts of 45 to
50 mph are likely (55-80 percent chance) into the desert. Winds
will continue into late Tuesday morning or early afternoon. A
weak upper-level ridge develops for late Tuesday into
Wednesday. Another shortwave trough passes over Central CA late
Wednesday into Thursday. Precipitation, if any, will be light
with mainly slight chances, or 20 to 30 percent POPs, limited to
northern portions for this period.

A warming and drying pattern is in store Friday into early next
week as a relatively strong ridge of high pressure develops
over the Western U.S. Mainly seasonal temperatures prevail until
the weekend, and above normal daytime highs prevail by next
Monday, although some warmer than average temperatures creep
into the Kern County desert as early as Sunday (up to a 40
percent chance of highs at 80 degrees or warmer on Sunday with
chances rising to 50 to 85 percent next Monday), while the
Central Valley's highs could be approaching 80 degrees next
Monday (about a 40-80 percent chance). Latest CPC outlooks at
both the 6-10 day and 8-14 day periods continue to reflect odds
tilted towards above average temperatures and below average
precipitation.

&&

18Z Monday Update...
