Synopsis
An upper level ridge of high pressure will bring warm and dry
conditions to the area thru this week, with near record
temperatures expected through mid week, including thanksgiving
day. The high will weaken by next weekend, resulting in increasing
onshore flow and cooler temperatures.

Short term (tonight-wed)
some high clouds were streaming over the forecast area this
evening, with more off the coast slated to move in overnight.

Generally fair skies with varying amounts of high clouds should
prevail across the region overnight, altho for slo sba counties,
partly to mostly cloudy skies at times can be expected. Locally
gusty NW to N canyon winds were noted this evening along the sba
county S coast and santa ynez range. These winds should gradually
diminish overnight. Otherwise, weak offshore low level flow is
expected over the region thru the night.

There was upper level ridging with 500 mb heights around 580 to 582
dm over swrn ca this evening. This upper ridge is forecast to
gradually build and expand over the region Mon thru wed, with 500 mb
heights by Wed reaching to 590 to 592 dm over the region.

It looks like varying amounts of high clouds will continue to move
into the forecast area Mon into Mon night, otherwise fair skies will
continue. Mostly clear skies should then develop by early tue
then continue thru wed.

Northerly gradients will increase some late Mon and Mon night,
with gusty N canyon winds expected for the sba county S coast and
mtns, some gusts to advisory levels possible. Gusty NW winds can
also be expected in the l.A. Vtu mtns along the i-5 corridor mon
evening, then transition to N to NE winds and expanding S into the
favored foothills and vlys of vtu l.A. Counties later Mon night
into Tue morning. Locally gusty NE winds will be possible over
these areas of vtu l.A. Counties again Tue night into Wed morning.

Otherwise, there will generally be weak offshore low level flow
over swrn ca Mon thru wed, especially night and morning hours.

The rising 500 mb heights, warming boundary layer and 950 mb temps,
and offshore flow, will all help to bring much warmer than normal
temps to the forecast area, especially Tue and wed. Near record to
record high temps will be possible for several climate stations tue
and especially wed, with temps on Wed 15 to 20 deg above normal for
many areas. Temps in the warmest vlys and inland coastal areas
should reach the mid 70s to lower 80s on mon, mid 80s to low 90s on
tue, and low to mid 90s on wed. Even overnight temps should be very
mild in the breezy foothill and lower mtns Wed and Thu where lows in
the low to mid 70s will be possible.

***from previous discussion***

Long term (thu-sun)
upper level ridge of high pressure and offshore flow near the
surface is expected to weaken slightly on thanksgiving day. This
may bring a few degrees of cooling near the coast, but inland
areas still expected to see record breaking temperatures, with
valley areas once again climbing into the 90s.

The ridge flattens out and begins to shift eastward Friday into
Sunday as a large upper low moves out of the gulf of alaska and
approaches the west coast. Gradients will reverse and become
weakly onshore. This is expected to bring a cooling trend through
the period, with increasing high clouds over the weekend. At this
point, it appears that any precipitation threat next weekend will
remain across northern california and the pacific northwest.

Moderate confidence in the forecast. A SCA remains in effect for

afternoon and evening. Otherwise, SCA conditions are not expected
through Wednesday night. Finally, SCA level winds are likely
across much of the outer waters Thursday and Friday, with sub-sca
conditions elsewhere. Seas will increase somewhat late in the week
but will remain below ten feet through the period.

In addition, tide and current are influenced by storms, river flow, and other factors beyond the ability of any predictive program.
