Synopsis
Weak offshore winds will develop through and below passes and
canyons as flow turns offshore on Tuesday, bringing drying and
warming inland. High pressure aloft will continue the warming
inland this week, but a shallow marine layer will keep the coast
cooler, along with some low clouds at times. Cooling will spread
inland next weekend, along with more clouds, and even a chance of
showers early next week.

Discussion For extreme southwestern california including orange...

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

update...

scattered showers and even a few thunderstorms developed over the
mountains this afternoon, a few of which drifted into the valleys.

There was one report of pea size hail in san diego country
estates. Areas around julian received around one-quarter inch of
rain, with less than one-tenth inch elsewhere. Activity has since
ended.

Marine stratus is a ways off the coast with only a couple small
patches showing up in southern orange county. Expect low clouds to
be somewhat slow to develop tonight. Hi res models do show a
coastal eddy spinning up overnight, which should help usher in
some of the low clouds and fog in the coastal areas and far
western valleys by Tuesday morning. Further inland, weather will
remain benign overnight.

Previous discussion...

an upper level low will continue to dig southeast tonight. By tue
morning, the low center should be over far NW mexico, setting up
northern portions of the CWA for some offshore winds. These are
not expected to be strong, but will cause further drying and
warming inland where daytime temperatures will be much warmer this
week. Along the coast, onshore flow is expected to hold a shallow
marine layer, keeping the days much cooler, with some patchy
marine clouds at times.

A broad ridge aloft will dominate the weather through the midweek
period, with fair skies most areas away from the immediate coast.

Temperatures will be some 5-10f above average most areas, although
not nearly as much along the coastal strip due to the marine layer
and afternoon sea breezes.

Looking ahead to the weekend... The 12z ECMWF gfs operational runs
continue to show a closed low moving across socal Sun mon. It looks
strong enough to generate widespread showers at this point, and low
pops are in the forecast for now, but likely to go higher if the
models stay on track. Increasing onshore flow over the weekend will
bring cooler weather and a deeper marine layer as well.

Aviation
230400z... Coast valleys... Patchy coastal stratus will continue
through 09z then increase between 09z and 12z, mainly within 15
miles of the coast. Bases will lower to 800-1300 feet msl with tops
to 1500 feet msl. Local vis 2-4 miles will occur in the coastal
valleys. Remnant clouds above 8000 feet msl will dissipate by 06z.

Clearing of the stratus will occur in most areas 15-17z Tue with
clear skies and unrestricted vis through early Tue evening.

Mountains deserts... All shra tsra have dissipated, and any remnant
clouds above 8000 ft msl will dissipate by 06z. Areas of N ne
surface winds 20-30 knots with local gusts 35-45 knots will occur at
times mainly in the san gabriel san bernardino mountains far
northern coachella valley especially 09z-20z Tue with decreasing
winds after that. Unrestricted vis will prevail through early tue
evening.

No hazardous marine weather is expected through Saturday.
