Synopsis
Surface high pressure over the central rockies will continue to
supply a cool and dry air mass to the region with another round of
frost and freeze conditions for cooler interior areas through
Sunday morning. A ridge of high pressure building into the region
early next week will bring significant warming with widespread
record heat possible mid-week, including thanksgiving day.

Short term (sat-tue)
clear skies covered the forecast area this evening with little
change expected overnight. Gusty sub-advisory level NE winds were
noted this evening mainly across the foothills and mtns of vtu l.A.

Counties. Pressure gradients for lax-dag at 03z was -4.6 mb which
was stronger than the 00z NAM was predicting. The good offshore
gradients will persist overnight with the gusty NE winds expected to
continue in these areas. For the antelope vly and interior vlys of
slo sba counties, light winds, clear skies and a dry air mass will
result in good radiational cooling tonight. Low temps in these areas
are expected to drop into the mid 20s to low 30s, and freeze
warnings and frost advisories are in effect overnight into sun
morning. Please see the latest non-precipitation weather message
(laxnpwlox) for further details on the freeze warnings and frost
advisories.

A flat upper ridge over SRN ca this evening is forecast to slowly
build over the area Sun thru tue, with 500 mb heights rising to 588
to 590 dm by Tue afternoon.

Dry weather with a gradual warming trend is expected across the
region Sun thru tue. Mostly clear skies for the most part will
prevail Sun and again on tue, while a weak disturbance moving N of
the region should bring mainly mid and hi clouds clouds to the area
sun night into Mon night, with partly to mostly cloudy skies
expected. Some offshore low level flow night and morning hours will
persist thru tue, keeping any low clouds off the coast.

Temps will be a few degrees above normal for most areas on sun, then
increase to much above normal by tue. Highs in the warmest vlys and
inland coastal areas are expected to reach the mid 70s to around 80
on sun, upper 70s to lower 80s mon, and mid 80s to around 90 on tue.

***from previous discussion***

Long term (wed-sat)
Wednesday and thanksgiving day expected to be the warmest days of
the week, as the upper level ridge of high pressure continues to
strengthen, with heights peaking at 592 dm. During this time,
temperatures could reach record levels, with highs in the lower
to mid 90s across many valley areas, and possibly inland portions
of the coastal plain. The unseasonably hot and dry conditions
combined with breezy offshore conditions will continue to bring
elevated fire weather concerns during the extended period. The
upper level ridge flattens out Friday and this will bring some
cooling to all areas but especially the coast. Additional cooling
and increasing high clouds expected by next Saturday as a weather
system approaches the california coast.

Aviation 19 0615z.

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.
