.DISCUSSION...
Clear, dry conditions are favorable to start today and continue
through the weekend as an approaching high pressure ridge
builds over central California across the next few days. A weak
trough has the chance to move through the northern reaches of
our CWA Monday, however there is less than a 10 percent
probability for measurable rainfall. Dry conditions will set up
further into much of next week as a stronger ridging pattern
approaches. Before then, temperatures this afternoon will
largely be near normal for the region, but will warm up to ten
degrees above season averages on Sunday. The potential early
week system will bring slightly cooler, but above normal
temperatures to the region, however the advancing ridge is
expected to increase highs again in the mid- to late-week
period. Here are the probabilities to exceed 80 degrees for
select locations of the San Joaquin Valley each day through next
Thursday.

There is a signal from ensemble members for a weak system to
move through the region next weekend, however probabilities for
24 hour accumulations greater than 0.01 inches are less than 25%
for the entire area. Extended outlooks from the NWS CPC show a
70 to 80 percent chance for above normal temperatures and a 40
to 50 percent chance for below normal precipitation in the 6 to
10 day period. In addition, there is a 40 to 50 percent chance
for above normal temperatures and a 40 to 50 percent chance for
below normal precipitation in the 8 to 14 day period.
