.DISCUSSION...
Satellite loops show the upper-level low along the coast near Pt
Conception. At this time, this feature is bringing showers to
our southern areas, including in the valley and West Side hills,
as well as Southern CA. These showers are spreading northward
and are approaching Fresno. This is a cold system for this time
of year, with snow levels expected around 5,000 feet. It will
also produce unstable conditions, sufficient for a slight chance
of isolated thunderstorms for this afternoon and evening. In
addition, gusty winds will develop this afternoon and continue
until late tonight/early Sat AM. Showers will continue
overnight into Sunday morning, though mainly over the higher
terrain. Amounts will generally be light over most of the
region, based on latest best/worst case scenario amounts (or
anywhere from a few hundredths of an inch to just above 0.25
inch in the SJ Valley). Also, amounts in the Sierra Nevada will
range from 0.50 inch to over 1.00 inch in the highest
elevations, with several inches of snow up to a foot; however,
in the worst case scenario, amounts could exceed 1.50 inches
(about a 10 percent chance). By Sunday morning, some low clouds
will linger above the Central Valley, though the favored areas
are towards the southern and eastern sides due to northwest flow
aloft.

Cooler than normal temperatures will last through at least
Sunday, before a ridge of high pressure moves in and builds.
Expect temperatures closer to seasonal averages on Monday and
back to above normal by Tuesday. Well above average temperatures
are in store for Wednesday until Friday before temperatures
lower back towards normal by next weekend. Another trough of low
pressure will bring a chance for some precipitation to mainly
the mountains next Saturday, although it doesn`t appear quite as
cold as the current one. More to follow, as we get closer.

Current 6-10 day and 8-14 day outlooks from the Climate
Prediction Center, overall favor above normal temperatures but
near to above average precipitation. However, it appears
periods with cooler or seasonal temperatures combined with
precipitation will be relatively brief, as both of these periods
cover the early part of May.
