area forecast discussion... Updated
national weather service san diego ca
620 am pdt Thu mar 23 2017

Update
Added showers to coastal and valley locations of san diego
county, as well as the foothills of the san bernardino county
mountains with this update. The hrrr shows showers decreasing by
late morning, with a few heavier showers developing over inland
san diego county. The rest of the forecast remains on track.

Synopsis
Isolated to scattered showers will linger over some areas west of
the mountains through this morning. Otherwise, gradually clearing
weather is expected today with areas of gusty winds in the
mountains and deserts. Fair weather will continue through Friday.

A weak trough of low pressure could bring a few showers Saturday.

Another trough on Monday will bring some strong winds in the
mountains and deserts, and could bring a few showers. Temperatures
will average a little below normal through early next week.

Discussion For extreme southwestern california including orange...

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

isolated to scattered showers continue early this morning, but
mainly in foothills, mountains and the san diego county
coast/valleys. These will continue to decrease and end by late
morning. Winds in the mountains and deserts this morning will
continue to gust over 30 or even 40 mph in the usual top spots,
but will decrease during the day. Skies will gradually clear from
northwest to southeast today and, despite the sunshine, it will be
a cool day. Brief high pressure allows for a fair and warmer day
Friday. Some semblance of a marine layer could produce a few
clouds in the coastal basin tonight into Friday. A new trough of
low pressure barges in Friday night and quickly zips through
california on Saturday. Not a lot of moisture or energy, but just
enough to justify a chance of showers. Sunday appears fair and
dry, but cool. The next trough of low pressure on Monday is very
similar to Saturday's. The chance of showers is quite small, but
this system could bring stronger winds to mountains and deserts.

Tuesday and Wednesday look fair under fleeting high pressure
aloft. Another big trough appears Thursday or Friday. We seem to
be in a progressive pattern that keeps sending deep troughs of low
pressure through the southwest, with southern california on their
periphery. That will keep our weather on the cool side. If these
troughs take a more direct path into our region it could mean
showers and/or winds.

Aviation
230900z... Isolated showers will gradually taper off through 18z.

Sct- bkn cloud layers 2500-6000 ft msl along/west of the mountains
this morning. Higher terrain remaining partially obscured in
clouds/fog/precip. After 15z, few-sct clouds above 3000 ft msl and
unrestricted vis.

Through 15z... West winds 20-30 kt with gusts 35-45 kt along the
ridges and desert slopes with mod-stg up/downdrafts and llws over
and east of the mountains. Winds gradually weakening during the day
Thursday.

Marine
West-northwest winds 20-25 kt with local gusts to 30 kt over the
outer coastal waters and combined seas near 10 ft will create
hazardous boating conditions. A small craft advisory remains effect
for the coastal waters through this afternoon. Winds and seas will
diminish by Thursday evening.

Beaches
Elevated surf will hit the beaches as a west northwest swell
increases across the local waters today. A beach hazards statement
was issued for surf of 5 to 7 ft. The surf will gradually lower this
evening.

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