.DISCUSSION...

Dry conditions with above average temperatures continue today
as a high pressure ridge builds over central California. The
ridge is expected to strengthen for Sunday and Monday, with
afternoon highs across the region warming to eight to ten
degrees above normal for this time of year. 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. Similar conditions to the weekend will set
up into much of next week as a stronger ridging pattern
approaches. 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.

Visalia        2% 65% 65% 30% 70%  90%  80%

There remains 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 40 to 60 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.
