AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE SACRAMENTO CA
847 PM PDT Mon Apr 14 2014

.Synopsis...
Dry weather with well above normal high temperatures continuing
through Thursday with a slight chance of showers over the northern
mountains on Friday into the weekend. Breezy northerly winds possible
Tuesday night and Wednesday.

&&

.Short Term Discussion...
The tail end of a very weak shortwave is moving into northern
California this evening. High clouds will be moving through the
region overnight that may cause some minor viewing problems of
the eclipse overnight.

Slightly cooler air will continues to advect into the region for
Tuesday and winds will become northerly again to offset the
cooling effects for the valley but the Mountains should see some
slight cooling. Varying amounts of high clouds will pass through
the region over the next day.

Conditions still look dry over the interior through Thursday
morning. Surface high pressure will strengthen to the north and
over the Great Basin to bring breezy conditions and slightly
warmer temperatures for Wednesday. A slightly stronger shortwave
will bring a slight chance of showers over the mountains late
Thursday and Thursday night.

.Extended Discussion (Friday through Monday)

Models continue to struggle with the weak storm waves that could
brush NorCal from Friday into the weekend. This first wave late
Thursday into early Friday morning could bring a slight chance of
light showers to the Northern Sacramento valley and surrounding
terrain. Some light, isolated showers could linger on Friday in
the mountains. On Saturday, the latest models are showing a drier
trend so have lessened the slight chance of showers to just the
highest elevations within our CWA. The CNRFC is estimating that
total rain amounts from Thursday through Saturday will only amount to
a few hundredths of an inch with some local areas getting around a
tenth of an inch. For Sunday, the ECMWF and GFS are showing a dry,
ridging pattern while the GEM shows another weak trough brushing
NorCal so have kept minimal areas of slight chance of showers.
Despite the low confidence in details, impacts will be minimal
with these weak storm waves. JBB

hours. Just some high clouds from a weak cold front passing to the
north tonight. Generally light southerly winds through the rest of

and northwest winds generally at or below 10 kt for the northern
San Joaquin Valley. Winds shift to northwest across the Valley
Tuesday around 5-10 kt, with west winds gusting to 25 kt over
ridges in the Sierra. EK
