313 pm pdt Tue mar 19 2019

Synopsis
Last day of dry and mild weather today. Precipitation chances
return tonight bringing high mountain snow with travel delays
through Wednesday night. Another wet system is possible late
Friday into Saturday.

Discussion
Upper trough with negative tilt orientation currently west of the
bay area will move east through norcal tonight. There is not a
lot of moisture with this system. Although, a reasonable amount of
mid-level instability will allow scattered showers and isolated
thunderstorms to develop this evening, best chances will be from
7 pm to 2 am. Snow levels will start out pretty high, above 7000
feet, but lower to 5500 feet by Wednesday. Rainfall over the
valley will be generally light from 0.25-0.50 inches, but locally
heavier in thunderstorms, also some small hail will be possible in
any stronger storms. Snowfall at pass level will be 4 to 8
inches, heaviest period will be after midnight tonight.

Showers are likely to decrease some Wednesday morning, but
atmosphere is expected to again turn unstable during the
afternoon. A better shear profile with increasing southeast low-
level flow will give storms better organization and it is
possible the strongest storms will be Wednesday afternoon, instead
of this evening. Scattered snow showers to continue over the
mountains with accumulations dependent on where convection sets
up.

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, but not expecting significant precipitation.

.Extended discussion (Saturday through Tuesday)
guidance for the weekend continues to show a trough passing
through the region on Saturday with weak ridging building behind
it Sunday. Models have trended wetter over the past few runs. Rain
and snow showers will be likely over the foothills and the ridges
Saturday. Drier weather expected by Sunday. Model and ensemble
guidance continue to hint at wet weather for early next week, with
a broad low pressure system sitting off the west coast. Rain
could make into northern california as early as Monday morning,
but the timing is likely to change as we're fairly far out in the
extended forecast.

Aviation
Vfr conditions expected with areas of MVFR possible after 03z due
to showers. Isolated valley thunderstorms will be possible
through 06z Wednesday and again between 18z Wednesday and 03z
Thursday. Southerly winds increase tonight becoming 10-20 knots by
12z.

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

Almost all of these also make simplifying assumptions so they are not totally accurate even if there are no errors. Please verify all results. 5) Weather information is from numerious of sources and is presented automatically. It is not checked for accuracy either by anyone at L-36.com or by the source which is typically the US Government. See the NOAA web site for their disclaimer. Finally, tide and current data on this site is from 2007 and 2008 data bases, which may contain even older data. Changes in harbors due to building or dredging change tides and currents and for that reason many of the locations presented are no longer supported by newer data bases. For example, there is very little tidal current data in newer data bases so current data is likely wrong to some extent. This data is NOT FOR NAVIGATION. See the XTide disclaimer for details. In addition, tide and current are influenced by storms, river flow, and other factors beyond the ability of any predictive program.
