1043 am pdt Mon may 29 2017

Synopsis
Temperatures a little above normal for today followed by a
cooldown Tuesday. Isolated afternoon showers or thunderstorms
possible over the mountains into mid- week.

Discussion (today through Thursday)
a weak shortwave is along the coast and is not projected to move
inland until Tuesday. This will help to keep moderate to strong
delta breeze going throughout the day today and through Tuesday.

The models are indicating the best instability over the next
several days occurring this afternoon over the sierra nevada along
the crest.

The trough axis moves inland Tuesday and we may continue to see
some afternoon thunderstorms along the crest from around alpine
county southward. A broader trough with more moisture will move
through Wednesday and may even bring a mix of light showers and
sprinkles to the valley. For now have left out any mention of
thunder with the models not indicating great enough instability
but we will have to re-evaluate that as we get closer to
Wednesday. Thursday will be a dry day for the western slopes with
zonal flow over the region and the better chances for anything
would be east of the crest.

Little change in temperatures is expected today other than in the
delta and sacramento region which will have some cooling due to
the stronger delta breeze today and low clouds lingering in the
bay area most of the day. Cooling all areas will occur both for
Tuesday and Wednesday with the coolest day of the week likely to
occur on Wednesday.

.Extended discussion (Friday through Monday)
dry weather Friday as zonal flow continues. A weak shortwave
returns along the coast for Saturday and Sunday and may help to
bring back some thunderstorms along the crest. For now conditions
are forecast to be dry but that may change. Temperatures will warm
a little above normal for this time of year but remain pleasant.

Aviation
Vfr conditions expected through the next 24 hours for TAF sites.

Winds generally 10 kts or less, increasing to up to 15 kt with
gusts up to 20 kt after 00z in the southern sacramento valley and
northern san joaquin valley. Gusts to around 30 knots in vicinity
of the delta. Isolated tsra possible in the higher mountains,
18z- 06z.

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. 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.
