Area Forecast Discussion
National Weather Service Sacramento CA
335 AM PDT Tue Apr 4 2017

.SYNOPSIS...
Dry and warm weather continues through Wednesday. Stormy weather
returns Thursday with heavier precipitation Friday and into the
weekend, potentially bringing heavy mountain snow, valley
thunderstorms, and strong winds.

&&

.DISCUSSION...
Mid and high clouds are beginning to increase across interior
NorCal. Current temperatures are in the mid to upper 20s in the
colder mountain valleys with mainly 40s to mid 50s elsewhere.

Upper ridge transits the area today then shifts east into the
interior West on Wednesday. Dry and mild weather will continue
across the region despite periods of cloudiness.

Upper trough presently over the Gulf of Alaska will continue to
gradually approach NorCal through the remainder of the week.
Shower chances are expected to hold off until Thursday when the
initial short-wave lifts out across NorCal ahead of the main
trough.

Models continue to pinpoint Thursday night into Friday as a
particularly active period of weather for the region as a stronger
wave moves into NorCal tapping deeper moisture and bringing
increasing rain, mountain snow and strong gusty southerly winds.

&&

.EXTENDED DISCUSSION (Saturday THROUGH Tuesday)
After the brunt of the storm on Friday, NorCal will continue to
have showery, unsettled weather into early next week. On Saturday,
our region will have light valley rain and light to moderate
Sierra snow as snow levels lower between 3500-4500 feet. Since the
main cold front will have tracked eastward, clearing behind the
front plus lingering instability could trigger a slight chance of
afternoon thunderstorms. Moving into Sunday, valley rain is still
possible and snow levels could lower to around 3000 feet, however,
any additional rain/snow accumulations will be light.

Models suggest that another storm is set to move across NorCal
late Sunday into Monday. The ECMWF looks much stronger and wetter
with this system compared to the GFS run. Have chances for
precipitation across our region on Monday diminishing early
Tuesday, but details on this storm are still vague. JBB

&&

.AVIATION...
VFR conditions for the next 24 hours. Current TAF site winds are
light and variable...expected to become light southerly winds this
morning and through much of the day. Wind speeds less than 10
kts. JBB

&&

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