Area Forecast Discussion
National Weather Service Sacramento CA
305 AM PDT Tue Mar 28 2017

.Synopsis...
Dry and milder weather expected for NorCal through most of
Wednesday. Another system will brush the region late Wednesday
through Thursday with a few showers. Dry and warmer weather
returns for the weekend.

&&

.Discussion...
Upper ridge is moving onto the West Coast with mainly clear skies
across interior NorCal early this morning. Current temperatures
generally range from the mid 20s and 30s in the mountains to the
40s and lower 50s elsewhere.

Dry and milder weather is expected over the region today and
Wednesday with temperatures returning to around average or a
little above. Breezy northerly winds will continue today across
the Central Valley before decreasing tonight.

The next weather system is forecast to approach the region
Wednesday night before sliding southeast into the Great Basin on
Thursday. It is expected to bring light QPF to mainly the
mountains, though eastern portions of the Central Valley will see
the best chance for a few showers Thursday. A few inches of
accumulating snow is expected across the higher elevations of the
northern mountains and northern Sierra.

Dry and breezy weather expected to return Friday as the system
shifts further to the east and high pressure rebuilds over the
area.

&&

.EXTENDED DISCUSSION (Saturday THROUGH Tuesday)
High pressure rebuilds across Northern California on Saturday,
bringing a rapid but brief warming trend. High temperatures are
expected to be on the order 10, possibly 15 degrees warmer than
normal.

Longer range models continue to struggle with the details as a
trough breaks down the ridge. The ECMWF is much faster, with a
system brushing by far northeastern NorCal on Sunday. The GFS and
GEM bring a splitting trough to the region Monday. Neither
scenario is particularly wet. Given the low confidence forecast,
we made little change to the forecast. Dang

&&

.AVIATION...
VFR conditions across interior northern CA the next 24 hours.
North winds 10-20 kts with gusts to 25 kts after 17z. Dang

&&

.STO WATCHES/WARNINGS/ADVISORIES...None.
