Synopsis
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
thanksgiving.

Short term (tdy-mon)
a weak upper level ridge of high pressure is building across
southwest california. This in combination with offshore flow
near the surface will result in a gradual warming and drying
trend through the weekend. So far, offshore winds have not
been quite as strong as expected, with gusts generally in the
25 to 35 mph range across favored areas of los angeles and
ventura counties. If winds do not increase during next couple of
hours, will likely have to cancel wind advisory early. As of 9 am,
lax-daggett gradient has peaked at -4.5 mb with minimal upper
level wind support. The offshore winds combined with the warming
and drying conditions across coastal valley areas will bring
elevated fire danger through the weekend.

Meanwhile, some cold air advection across interior sections
combined with the drying air mass and light winds tonight will
result in even colder overnight temperatures tonight across
interior valleys. Currently have a freeze watch for the
slo interior valleys and cuyama valley, with a hard freeze
watch for the antelope valley(where lows are expected to fall
into the mid and upper 20s tonight in coldest areas).

Mostly sunny forecast today, then periodic mid and high
level clouds will stream across the area Sunday into
Monday. More significant warming expected to take place
by Tuesday as upper level ridge of high pressure strengthens
and flow near the surface remains offshore. By Tuesday
afternoon, expecting to see temperatures rise well into
the 80s.

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
above normal.

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
above normal.

Aviation 18 1800z.

during the Sunday night through Monday night period.
