I'm hoping that was an April Fool's joke. Kinda getting tired of it, although I hate to complain after the drought.
Nope, no April Fool's prank -
.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
