154 pm pdt Fri may 24 2019

Synopsis
Scattered rain showers and thunderstorms mainly mountains and
foothills today and Saturday as one low pressure system moves
east and another drops in to take its place. Locally heavy rain
possible. More widespread showers or thunderstorms on Sunday and
Sunday night with snow for the higher sierra elevations.

Afternoon mountain showers continuing through mid week. &&

Discussion
Showers and a few isolated thunderstorms have popped up over the
sierra early this afternoon, thanks to a upper level disturbance
moving through the area. Favorable conditions for shower and
tstorm activity will likely continue into the early evening hours,
with most of the precip staying confined to the terrain. However,
some shower activity may slip into the sacramento valley this
evening as the upper low drops farther southward. Overall
precipitation amounts are expected to remain light but some
embedded heavier showers thunderstorms could bring locally heavier
precipitation.

Looking to Saturday a pacific northwest trough will drop
southward through northern california and will mostly be an
inside slider type of system. Therefore, the biggest chance of
showers or thunderstorms will be over the eastern half of the
forecast area. Once again precip amounts overall will be light
but heavier showers will be possible. The passage of the trough
will also bring cooler air into the north state, putting our high
temperatures to a few to several degrees below normal.

Come Sunday, a stronger low pressure system is forecast to arrive
in northern california. Showers and thunderstorms will remain in
the forecast but over the entire CWA this time. This system will
usher in even cooler air which will drop snow levels and put our
daytime highs down to 10-15 degrees below normal. Snow levels will
likely drop to below pass levels, which will likely bring travel
impacts to the sierra. The greatest threat for snowfall and
potential accumulation will be Sunday - Monday morning, so
travelers should take note of the road conditions and forecast
before heading out. This storm system will shift eastward into
the great basin on Monday, placing the shower threat on our
eastern mountains. By the afternoon, snow levels should be above
pass levels with daytime highs climbing a bit although remaining
below normal.

.Extended discussion (Tuesday through Friday)
unsettled pattern continues through the period as ensembles
support troughing across the area through the week. Chances for
showers or thunderstorms expected over higher terrain throughout
the week, mainly in the afternoon and early evening hours.

Elsewhere, dry conditions are expected. Temperatures will be on
the rise through the period with valley highs in the upper 70s to
low 80s Tuesday, reaching into the mid and upper 80s by late next
week.

Aviation
MainlyVFR conditions at TAF sites next 24 hours. Local MVFR ifr
conditions in showers and thunderstorms mainly over the
foothills mountains and the N sac valley through the overnite hrs
obscuring higher terrain sustained winds less than 15 kts at taf
sites with local gusts to 20 kts. After sunrise Sat morning,
marine cloudiness spreading inland into the SRN sac vly with MVFR
cigs 015-025 expected.

Sto watches warnings advisories
None.

Almost all of these also make simplifying assumptions so they are not totally accurate even if there are no errors.

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.
