Surface high pressure settling in over the central rockies will
bring weak santa ana winds to portions of southwest california
Saturday. The dry and cool air mass will also support the first
freeze of the season for cooler interior areas this weekend. A
ridge of high pressure building into the region early next week
will bring a warming trend with record heat possible by
Short term (tdy-mon)
over the next three days a weak 577 dm ridge moving into the area
today will grow and expand to 585 dm by Monday afternoon. Strong
cold surface pressure over nevada will generate moderate offshore
flow this morning. Offshore flow will continue through Monday but
will weaken some each day.
It will be sunny today except in the cuyama vly where the offshore
flow is pushing some low clouds in from kern county. Sunday will
be sunny. Mondays partly cloudy sky forecast seem a little
overdone as the ridge looks pretty strong and should shunt the
clouds to the north of the area. All of the surrounding offices
wanted to keep the clouds in the forecast so they remain, but
would not be surprised if future shifts agree to mostly clear
The offshore grads will mix with just a little upper and thermal
support and bring low end advisory level NE santa ana winds gusts
to mountains and most of the vlys of la vta counties this morning
and early afternoon. There will be some more NE gusts Sunday
morning but they will be weaker and sub advisory.
Cool air will be pushed into the interior from the east. The clear
skies and dry air will bring additional cooling to the already
cool air and will bring near freezing conditions to interior vlys
and deserts this morning. More cool air will spill in today and
there is a chc of freezes in the slo and cuyama vlys and even hard
freeze conds in the parts of the antelope vly. Please see the
product laxnpwlox for more details on the frost freeze advisories
Max temps will be the main story over the next 3 days ESP over the
coasts and vlys. Today will be 4 to 8 degrees warmer than ydy and
then there will be an additional 1 to 3 degrees of warming both
Sunday and Monday. The cool air intrusion will keep the interior
from warming much today but the warmer trends will start there
Sunday. By Monday MAX temps will be 8 to 12 degrees above normal.
Long term (tue-fri)
on Tuesday the ridge grows further and hgts reach 589 dm. Offshore
flow continues from the north but the e-w grads will be neutral.
Still it will be enough to add a few more degrees to Monday's
already warm readings.
The ridge and the offshore peaks on Wednesday as do MAX temps.
There will be some 15 to 25 mph sub advisory wind gusts in the
morning. MAX temps will increase another 4 to 6 degrees and there
will be plenty of MAX temps in the lower 90s across the vlys and
interior coastal sections. MAX temps will be 15 to 20 degrees
The ridge weakens just a touch on thanksgiving as does the
offshore flow. There may be a degree of cooling but more likely
max temps will equal Wednesday's warm values.
The ridge flattens out Friday and this will bring cooling to all
areas but ESP the coast. Still MAX temps will 10 to 15 degrees

feet. The top of the inversion was around 1600 feet with a

winds across the outer waters will continue to diminish as they
shift to the northeast this morning. Locally gusty offshore winds
will develop across the nearshore waters from point mugu to santa
monica by midday and may reach small craft advisory (sca) levels
at times near canyon outlets before diminishing late this afternoon.
Winds speeds across the outer waters will increase on Sunday and
there is a forty percent chance of speeds reaching SCA levels
during the Sunday night through Monday night period.

These are not intended to be fact, they are my opinions. 4) Small programs that generate result presented on a web page. Like any computer program, these may and in some cases do have errors. 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.
