327 pm pdt Wed mar 20 2019

Synopsis
Periods of light rain and mountain snow through the evening, then
again Friday and early next week. Enough snowfall possible for
travel delays over the sierra during each round of precipitation.

Discussion
Upper trough with negative tilt orientation currently moving
through norcal. There is not a lot of moisture with this system.

Although, abundant instability has allowed scattered showers and
thunderstorms to develop this afternoon. Main threat will be small
hail and brief heavy rain, have had numerous reports of pea size
or slightly larger hail. Activity, will diminish after 7 pm. Snow
levels are currently around 5000 feet. Additional, snowfall at
pass level will be 2 to 3 inches this evening. Snow showers will
diminish after midnight.

Dry conditions look to return for most valley locations Thursday
into Friday morning with scattered light showers continuing over
the mountains, not expecting much snow accumulation.

Next system will move in on Friday with more wet weather and
mountain travel delays. Best precipitation chances will be Friday
evening and overnight. Snow levels will start around 5500 feet and
fall to 4500 feet Saturday morning. Snow accumulations of 4 to 10
inches will be possible with the highest rates during the sierra
rush hour travel time between 6-11 pm. Travel delays with chain
controls can be expected during this time. Valley rainfall amounts
will likely be around 0.50 inches. Precipitation will diminish
rapidly Saturday afternoon with dry conditions into Sunday.

.Extended discussion (Sunday through Wednesday)
a temporary break in the active wet pattern is expected to
conclude the weekend. Transitory shortwave ridging will move
through on Sunday affording a mild, precipitation-free day across
the region. By early Monday morning, an expansive upper low
lurking offshore will provide an impetus for unsettled conditions
to begin next week. The 06z GEFS atmospheric river detection tool
showed a nice cluster of ensemble members, generally centered over
37-39n latitude. At this point in time, such ensembles maintain a
"weak" designation for this atmospheric river signature. Given the
broad, slow moving nature of the mentioned low, precipitation
chances will linger through the middle of next week. However, it
will not be a complete washout as there will be breaks in between
the advancing shortwaves. There is reasonable confidence in this
pattern although GEFS ensembles exhibit some spatial spread
suggesting timing differences. In addition to the increased
precipitation chances, periods of gusty winds may be possible with
each approaching shortwave. While likely to change, next week's
snow levels should range between 5,000 and 6,000 feet.

High temperatures to conclude the month will be slightly below
average with low mid 60s across the valley and mid 30s to lower
40s over the mountains. ~bro

Aviation
Overall we will seeVFR conditions the the next 24 hours but
MVFR ifr will be possible at times through 05z due to scattered
showers and thunderstorms. Breezy winds this evening will diminish
overnight falling under 10 knots.

Sto watches warnings advisories
Winter weather advisory until 11 pm pdt this evening for west
slope northern sierra nevada.

In addition, tide and current are influenced by storms, river flow, and other factors beyond the ability of any predictive program.
