Synopsis
Cooling continues into Friday with near to below normal
temperatures. Slow warming trend this weekend into early next
week. Isolated afternoon showers or thunderstorms possible over
the northern sierra through the weekend.

Discussion
Temperatures are again running much cooler this evening in many
areas. Tonight the central and north end of the valley is running
much cooler with temperatures down around 12 degrees from 24 hours
ago. The sacramento region is only a couple of degrees cooler
since it had cooled off last night. A low pressure area will
remain centered east of the region and will help to keep
temperatures cooler than normal for Friday and near today's
highs.

Nam is dry on Friday while the GFS indicates possible isolated
convection over the sierra nevada. The GFS does not indicate much
moistures though so leaning on no convection occurring again.

Previous discussion (today through Sunday)
Model analysis with water vapor imagery showed a broad trough area over
the west with the latest trough base moving through northern
california. Satellite imagery showed cloud cover from the delta
diminishing with other cloud cover remaining off the coast. Radar
returns across the area were clear. Latest surface pressure
gradient trends continue to weak and surface breeze has lessened,
but continues through delta influence areas.

Model forecasts are in good agreement with a shortwave positively
tilted trough moving across the great basin to the east, and the
trough will continue to exit the area by Friday. Southwest
oriented winds will continue to bring chances for marine layer
clouds into the delta and surrounding valley locations, but model
surface pressure gradients do not appear as strong as the past 24
hour period. Therefore, not expecting as strong of a breeze
overnight, but the delta will still see winds up to 20 mph.

Temperatures across the area will range between 5 and 10 degrees
below normal through Friday. In the vicinity of the passing
trough, mountain showers and thunderstorms are possible with some
mid level instability, although confidence at this point into
exact timing and formation is low.

Building ridge of high pressure from the eastern pacific will
bring a return of near normal to slightly above normal
temperatures for memorial day weekend. Afternoon instability over
the mountains could lead to the development of an isolated
thunderstorm or two that could produce small hail and brief heavy
rain downpours.

.Extended discussion (Monday through Thursday)
a strong ridge will be in place to start the extended period and
that will bring hot temperatures. We will see highs near 100 in
the north valley on Monday and Tuesday with 90's elsewhere in the
valley and 60-70's in the mountains. Some instability in the
sierra will lead to isolated thunderstorms during the afternoon
and evening but with little to no forcing chances are very low.

The ridge will be tracking east on Wednesday and we will start to
see some upper level energy spin off of an upper level low over
the gulf of alaska. Not expecting anything major with this system
but it could bring a few light showers or isolated t-storms to the
mountains. Wednesday would be the best chances but they still
look minimal at this time. This trough will also bring some
cooler temperatures as highs will be in the upper 80's to mid 90's
for the valley and 50-60's in the mountains. A delta breeze will
keep the delta areas a few degrees cooler.

Aviation
Vfr conditions expected this afternoon into the overnight. Gusts
to 30 knots will be possible in the delta with 10-15 knot winds
expected elsewhere. Winds diminish to under 10 knots after 14z.

Areas of clouds around 3000 to 5000 feet possible in the central
valley mainly between 12-18z Friday with local MVFR conditions.

Sto watches warnings advisories
None.

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.
