.SYNOPSIS...26/223 AM.

A low pressure system will bring cool temperatures, morning
drizzle, and gusty winds to the beaches, mountains, and deserts
today through Thursday. Winds will be the strongest this afternoon
and evening. Friday into early next week a warming trend is
likely, with temperatures reaching above normal by Sunday.

.SHORT TERM (TDY-THU)...26/223 AM.

An unusual for this time of year upper low will plunge into Nrn CA
today and will be centered over Red Bluff later this afternoon. It
will spin up a deep marine layer and some local drizzle (esp near
foothills). It will keep partly to mostly cloudy skies over most
areas through the day. Max temps will cool noticeably (3 to 6
degrees across the csts and 5 to 8 degrees across the vlys). Max
temps will only end up in the 60s today across the csts/vlys or 4
to 8 locally 10 degrees blo normal. Winds will be a major issue
today as the upper low will bring strong W to NW upper level flow
to the area esp the areas north of Pt Conception. Cold air
advection with the upper low will help drive these stronger winds
down to the sfc. Advisory level gusts will develop across most of
SBA and SLO counties as well as the Antelope Vly and the VTA cst.

Wednesday will be similar to today except for the winds. The
upper low with a central hgt of 555 dam will be over Bakersfield.
This location will shift the strongest upper level winds to the
south of LA county and this will reduces the wind speeds over SLO
to LA county forecast area. There be another round of morning
clouds with partly to mostly cloudy conditions lingering into the
afternoon. The upper low is quite dry, but there is enough
instability and lift to bring a slight chc of rain to the mtns as
well as SLO county and northern SBA county. There is also a slight
chc of a TSTM over the mtns if skies stay partly cloudy and allow
for some ground heating. Max temps across the csts/vlys will will
cool an additional 1 to 2 degrees while the mtns and far interior
will see 4 to 8 degrees of cooling. Cst and Vly max temps will
only reach the lower to mid 60s. Vly temps will end up 10 to 15
degrees blo normal while the mtns and far interior will be 15 to
20 degrees blo normal.

The low moves northward up to the Sacramento area on Thursday.
This will bring better upper level wind support back into the area
and the west to northwest winds will pick up again. It is likely
that the marine layer will be mixed out at this point so skies
will be partly to occasionally mostly cloudy. Still cannot rule
out rain across mtns and SLO county. The chc of a TSTM is less
than Thursday but still not zero as the area of best instability
will be further to the north. Max temps will warm a degree or two
as there will be a touch more sunshine but max temps will remain
well below normals.

.LONG TERM (FRI-MON)...26/223 AM.

The upper low will pull out of the area Friday and fairly zonal
flow will set up over the area. Hgts will rise from 566 dam Friday
morning to 575 dam Friday afternoon. Further hgt rises will bring
578 dam hgts Saturday afternoon; up to 582 dam Sunday and then
reaching 586 dam on Monday. Pressure gradients will revert back to
typical late May with weak onshore flow to the east in the morning
turning moderately onshore in the afternoon. In the N/S direction
the flow will oscillate between weak offshore in the morning and
weak onshore in the afternoon. There will likely be some morning
low clouds across the csts and locally into the vlys, but the
clouds should be gone by late morning. The sunnier skies and
rising hgts will combine to bring a big warm up. Friday should see
3 to 6 degrees of warming across the csts/vlys with 10 to 12
degrees across the far interior. Most areas will warm 4 to 8
degrees on Saturday and 2 to 4 additional degrees on Sunday. This
weekend warming should bring near normal temps on Saturday and
above normal temps on Sunday. Monday will round out the warm up
with 2 to 3 degrees of extra warming. On Monday max temps will be
in the mid 70s to lower 80s across the csts and 80s and lower 90s
in the vlys.

cat changes may be off +/- 2 hours. There is a 30 percent chc of
SCT conds in the afternoon.

.MARINE...26/228 AM.

For the Outer Waters, moderate to high confidence in current
forecast. Small Craft Advisory (SCA) levels are expected through
most of this afternoon. Then, a GALE WARNING goes in effect
from mid to late afternoon through late tonight. SCA conditions
will then follow through Wednesday night, or Wednesday afternoon
for PZZ676. Thereafter, conditions are likely to fall below SCA
levels for a short-time, before returning Friday night into the
weekend.
For the Inner Waters north of Point Sal, moderate confidence in
current forecast. Today through early Wednesday, high confidence
in a combination of at least SCA level winds (strongest in the
afternoon and evening hours) along with SCA seas. A GALE WARNING
goes into effect this afternoon through late tonight. Conds
should drop below SCA levels by Wednesday afternoon.

For the Inner Waters south of Point Conception, moderate
confidence in current forecast. SCA level W to NW winds are
expected across the Santa Barbara Channel today, around the
Channel Islands, and into Santa Monica Bay during the evening
hours. A GALE WARNING goes in effect for the Santa Barbara Channel
