.DISCUSSION...

An strong, deep, and cool upper low is moving into Central
California early this morning. This system looks to bring
mountain snow to the higher passes above 7500 feet today with a
probability of 45 percent of 3 inches of snow or more. The other
impact areas is the Mojave Slopes of the Kern County Desert
where a 40 to 75 percent probability of wind gusts exceeding 35
mph exists late this afternoon through the overnight hours. A
noteworthy fact is that there is a 40 to 55 percent probability
of setting new record low maximum temperatures at select
locations across the San Joaquin Valley today.

Tuesday The strong upper low exits into the Northern Rockies and
leaves behind a trough to keep temperatures on the cool side.
Another strong shortwave is diving into the trough late in the
period. The probability of temperatures remain below 80 degrees
ranges from 25 to 75 percent for the San Joaquin Valley.

Wednesday the shortwave deepens into another upper low and by
evening reaches the Bay Area. This system is warmer for the
Sierra Nevada with the cooler upper level temperatures moving
south and west of the Sierra. This will keep the snow at the
very highest elevations. The system is a bit more dynamic and
provides a better probability of thunder for the region.
Wednesday evening into early Thursday morning the probability of
thunder is 5 to 10 percent for the San Joaquin Valley and 10 to
20 percent for the Sierra Nevada north of Tulare County. The
probability of greater than 0.05 of an inch of precipitation
for the San Joaquin Valley late Wednesday into Thursday ranges
from 35 to 75 percent. The upper low weakens and slows down over
Central California on Thursday. The probability of temperatures
remaining below 80 ranges from 35 to 70 percent for the San
Joaquin Valley.

Friday the upper low lifts into the Great Basin and heights
begin to rise in the upper levels this will bring a drying and
warming trend to the region. The probability of temperatures
exceeding the benchmark of 92 degrees for normal highs is less
than 10 percent on Friday, 15 to 55 percent on Saturday, 50 to
60 percent on Sunday, and 60 to 70 percent next Monday. As we
get into the weekend the spread of temperatures at any point
location is approaching ten degrees, for example Fresno, the
range on Monday is from 89 to 99. The primary issue is the
persistent upper low over the southeastern US and its
development and progression that will allow or deny the Pacific
Ridge to translate further inland for warmer temperatures for
California.
