Synopsis weak surface high pressure will build over the great
basin Sunday and remain nearly stationary through Friday. This santa
ana weather pattern will set the stage for sunny, warm days, and
clear, cool nights through the end of the month. Northeast winds
will be strongest through the mountain passes and into the inland
valleys Sunday through Wednesday, increasing the threat for
wildfires.

Discussion For extreme southwestern california including orange...

san diego... Western riverside and southwestern san bernardino
counties...

Saturday was another unseasonably cool day with a couple record lows
(52 at vista and 53 at borrego), and a couple record low highs (55
at big bear and 56 at palomar mountain). The deep upper trough over
the southwest responsible for our cool spell will drift east and
gradually be replaced by a warmer airmass building in from the west.

The trough doesn't move too far east though, so the winds aloft will
remain northeasterly between the trough and a high amplitude ridge
that will form over the west coast Sunday through Tuesday.

On Tuesday night a shortwave digging down the east side of the ridge
will evolve into a closed low near las vegas, a position that could
add a little more mid level northeast wind support. So for the first
half of the week we will have a warming trend and likely see the
strongest offshore winds. While this won't be a very strong wind
event, there will be areas where the winds will be 15 to 30 mph in
the wind prone areas with gusts to 40 mph. On Thursday and Friday
both the upper wind support and surface pressure pattern weaken for
lighter winds. Warmest days will be Thursday and Friday.

Temperatures will increase a few degrees each day this week, with
the most rapid warmup west of the mountains due to downslope warming
from the santa ana winds. By Thursday and Friday the coastal and
valley temperatures will be 5-10 degrees above average, while the
mountains and deserts will be about where they should be temperature-
wise for late september.

Aviation
240300z... Coast valleys coastal slopes... Mostly clear skies and
unrestricted vis through Sunday... Except at the beaches and along
the immediate coastal strip where sct low clouds will linger at
times, but not likely to impact any of the TAF locations.

Gusty northeast winds will develop Sunday afternoon over the mtns
and along the coastal slopes... With gusts to 40 knots possible in
the most wind prone locations. This could produce weak to locally
moderate up downdrafts and llws over and west of the mtns.

Mountains deserts... Clear with unrestricted visibility through
Sunday.

Marine
No hazardous marine weather is expected through Thursday.

Fire weather
Offshore flow will develop on Sunday, and become gusty below the
coastal slopes, canyons and passes of san bernardino, riverside,
and orange counties Mon tue. The rh will drop considerably, on
Sunday with minimum daytime values down to as low as 10% through
Thursday. In the favored, offshore wind-prone areas, we are still
expecting to see occasional winds of 25 to 35 mph with isolated
gusts to 40 mph, especially Mon Tue mornings. Several hours of
near critical fire weather conditions are possible in these
foothills areas, mainly north of san diego county Mon Tue due to
low rh and winds exceeding 25 mph. However, with the limited
coverage and duration of critical conditions, no fire weather
product issuance is anticipated at this time. A significant
concern for the fire weather forecast is the longevity of the hot
and dry weather pattern for much of the work week. The medium
range models do suggest some improvement by next weekend as a
trough may develop along the west coast.

Skywarn
Skywarn activation will not be needed Sunday.
