230 am pst Mon jan 21 2019

Synopsis
Showers taper off across the region early today with a few
expected to linger into this evening across the higher elevations
of the northern sierra nevada. Dry weather will locally breezy
northerly winds expected through the week.

Discussion
Upper trough shifting east into the great basin. Radar shows
numerous showers continuing across the northern sierra west slopes
with a few lingering showers elsewhere. Current temperatures are
colder compared to 24 hours ago and range from the 20s in the
mountains to the mid and upper 40s across the central valley.

Trough continues to shift east the next several days allowing
ridging from the eastern pacific to shift over norcal beginning
tonight. Showers will taper off across the northern sierra today
with perhaps a few lingering along the crest into early this
evening. Elsewhere, clearing skies and northerly winds expected to
develop by this afternoon.

Upper high will build in Tuesday with dry and milder weather.

Northerly flow will continue with some patches of late night and
morning valley fog, mainly along the eastern edge of the valley.

.Extended discussion (Friday through Monday)
quiet weather is expected for the extended part of the forecast
due ti an amplified ridge across the eastern pacific setting up
shop. Mostly clear skies may lead to early morning fog most
mornings, which will then be followed by warmer than normal high
temperatures each day. Forecast highs for the valley each day will
be in the 60s, with the upper 40s and low 50s being seen at
higher elevations. Low temperatures will generally be around
climatological values.

Aviation
Satellite imagery this morning shows widespread high cloud over
the region with TAF sites reportingVFR conditions. There is some
clearing along the western side of the cwa, which could lead to
ifr MVFR conditions later this morning if the winds continue to
weaken. Once the low completely pushes eastward,VFR conditions
are expected during the daytime as high pressure will build over
the region. Ifr MVFR conditions will be possible tomorrow night
due to patchy fog developing.

Sto watches warnings advisories
Winter storm warning until 4 am pst early this morning for west
slope northern sierra nevada-western plumas county lassen park.

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.
