.DISCUSSION...
Today will be warmer than yesterday with more sunshine and a
little less humid. Moisture has generally moved out of the
region, except enough remains for afternoon and early evening
showers and thunderstorms over the higher elevations of the
Sierra Nevada for today and Sunday. Mist and haze will remain in
the Central Valley with a brief reduction in visibility as
temperatures near the dewpoint during the morning on Sunday. A
few locations in the southern SJ Valley reported visibility
around 1 to 2 miles briefly this morning. Latest satellite
imagery shows cloud buildups beginning over the Sierra Nevada
while the low clouds along the foothills evaporate late this
morning.
Convection becomes a little more widespread over the higher
elevations of the Sierra on Sunday with slightly increased
chances (10-15 percent today vs. 15-20 percent on Sunday).
Warming will continue into early next week, though not expected
unseasonably warm. Probabilities for highs in the lower 90`s
increase noticeably for Monday and Tuesday (50-80 percent) in
the Central Valley with lesser chances in the Kern County desert
(30-50 percent).
While Tuesday will be one of the warmest days next week, we`re
looking at the return of showers and thunderstorms across the
region. Even the San Joaquin Valley is looking at another
opportunity for some light to moderate showers with isolated
thunderstorms. Some remnant moisture will continue a slight
chance for showers in the valley into Wednesday, with the
mountain areas seeing a better chance for redeveloping
thunderstorms. Otherwise, a slight lowering in temperatures will
occur for Wednesday and the remainder of next week.
