Severe and potentially damaging winds this afternoon and evening
over the mountains and deserts...

Synopsis
Strong to severe winds will impact the deserts this afternoon and
evening as a powerful low pressure trough moves across the great
basin. The winds will decrease tonight. Cooler Friday behind the
trough with winds shifting to the northeast. High pressure
rebuilding over the region Saturday will bring sunny and warm
weather this weekend. Cooler early next week as another trough moves
in from the northwest.

Discussion For extreme southwestern california including orange...

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

strong winds are surfacing in the high desert this afternoon where a
62 mph wind gust was recorded at barstow-daggett airport at 1 pm.

Burns canyon had a gust to 67 mph.

A dynamic 546 dm upper low over western nevada is digging south with
an incredibly strong 300 mb 150kt jet over northern california.

Convection has formed along and ahead of the surface cold front in
nevada. The atmosphere down here is too dry, but the winds will be
very strong. 850 mb winds of 50-60 kt over the mojave desert will
shift southeast through evening. The high rez hrrr and WRF models
project the peak surface winds of 25-35 mph with gusts of 70 mph to
surface between 2-7 pm in the high deserts. Even stronger gusts are
possible where mountain waves surface on the eastern slopes of the
sbd mountains. Burns canyon may gust to 80 mph.

Some of this wind energy will also surface in parts of the coachella
valley and the san diego county deserts where gusts of 50-60 mph are
possible. Strong cross winds and reduced vis in blowing dust and
sand will create hazardous travel conditions. A high wind warning is
in effect through 11 pm this evening.

Onshore flow and a coastal eddy brought low clouds to the coastal
areas this afternoon. The clouds will spread a few miles inland
inland this evening, perhaps into the san diego valleys, before
retreating back to the coast early Friday morning as offshore flow
fills in behind the trough passage.

The deep upper low will be over northern az tonight and the winds
will shift from the west to the north through Friday morning. A
period of gusty north winds Friday morning will mainly impact the
lower deserts, the cajon pass and the santa ana mountains.

The trough slowly moves east over the weekend followed by ridging
and moderating temperatures Saturday and Sunday. An inside slider
trough will bring cooling Monday and Tuesday and gusty northwest
winds in the mtns and deserts, but much weaker than today.

A more pronounced ridge builds in Wednesday and Thursday for warmer
days. Temperatures will be way above average with coastal highs in
the 70s, valley highs in the 80s, mountain highs in the 60s, high
desert highs in the 80s and lower desert high in the 90s.

Long range outlook for late next week: a zonal pacific jet will
break down the ridge with bring rain to norcal, but at this time it
doesn't look like it will dig deep enough to bring rain to southern
california.

Aviation
302000z... Areas of low clouds and fog along the coast this afternoon
will spread 5-10 miles inland through 06z fri... Mostly in san diego
county. Expect bases 1000-1500 ft msl and tops to 2000 ft msl. Vis
restrictions are likely where clouds and terrain intersect. Low
clouds could spread inland to the coastal slopes by 06z, before
northeast to east winds develop and begin to clear out the low
clouds. Otherwise, mostly clear skies through tonight.

Mountains and deserts... Areas of winds 25-35 kt with gusts 40-50 kt
this afternoon through tonight near mountain crests, desert mountain
slopes and some lower elevation desert locations. Strong and
variable winds are expected at kpsp and ktrm, with peak winds likely
between 23-04z this afternoon/eve. Strong up/downdrafts and llws
will occur over and east of the mtns, with isolated vis reductions
in blowing dust/sand in the deserts. Winds will diminish after 09z
fri.

Marine
Strong west to northwest winds are developing this afternoon and
will continue into early Friday, particularly in the outer coastal
waters. A small craft advisory contains the details on winds and
seas. In portions of the outer waters, winds will gust over 30 knots
at times and combined seas could exceed 10 feet. Winds and seas will
diminish Friday morning. No hazardous marine weather is expected
through Sunday, but strong winds could return Monday.

Skywarn
Skywarn activation is not requested. However weather spotters are
encouraged to report significant weather conditions.
