Area Forecast Discussion
National Weather Service San Diego CA
925 PM PDT Wed Jun 8 2022
.SYNOPSIS...
Warming will continue into the weekend under strengthening high
pressure aloft. Most of the heat will be felt inland as onshore flow
and a shallow marine layer moderates coastal areas, with low clouds
and fog at times. The high will weaken by Sunday as a trough in the
westerlies to the north expands southward. Stronger onshore flow
will accompany the through over the mountains and deserts, driving
cooler marine air farther inland through early next week.

.DISCUSSION...FOR EXTREME SOUTHWESTERN CALIFORNIA INCLUDING ORANGE...
SAN DIEGO...WESTERN RIVERSIDE AND SOUTHWESTERN SAN BERNARDINO
COUNTIES...
Marine clouds were persistent all day today over the CA Bight, from
the islands, east to the SoCal Coast. Those clouds were spreading
slsoly inland this evening. The sfc pressure gradiet from the coast
to the deserts was running about 4 MBS onshore, and wind reports
mostly light. Our 00Z Miramar sounding showed a lowering and
strengthening inversion based now near 1500 FT MSL. The forecast
remains on track so no updates are planned this evening. Heat
Advisories and Warnings go into effect tomorrow over the deserts and
the Inland Empire.
From previous discussion...
.SHORT TERM (Through Saturday)...
A large ridge to the south will continue to expand over our region
the next few days, leading to a warming trend through the short
term period. As it does so, the marine layer will thin, keeping
low clouds confined to the coast and adjacent valleys. Clouds are
confined to the beaches this afternoon, though we expect greater
clearing each day Thursday through Saturday. The marine layer's
thin presence will also keep coastal areas moderated, while inland
areas will feel the heat.
A thermal ridge over the West will peak in intensity by Friday and
Saturday, where the hottest temperatures will be felt for this
event. NBM and MOS guidance point to Saturday as the hottest day
for the lower deserts, where Palm Springs and other locations will
peak near 115 degrees. Inland areas west of the mountains will be
warm as well, with widespread 90s to near 100 degrees for eastern
areas of the Inland Empire. Not only will it be hot during the
day, but quite warm at night in the lower deserts. Lows into the
low 80s are expected Friday through Sunday mornings. Remember to
stay hydrated and limit time outdoors during peak heating hours
each afternoon, including long hikes outside!
&&
.LONG TERM (Sunday into early next week)...
Model cluster analysis depicts a trough entering the West Coast
early Sunday into Monday. This will provide slight cooling across
the region with windier conditions across the mountains and
deserts. Gusty west winds are present in ensemble member guidance,
mainly 35 to 45 MPH eastern/northern areas of the mountains into
the deserts this weekend into Monday. There is still some
uncertainty about exact strength and timing of this trough, but
Sunday looks to be the windiest day overall across these areas. By
Monday, most areas will be close to average for high
temperatures. The cooling pattern looks to be short-lived, as
another ridge off the Pacific may come into the area and bring
another spell of hotter weather for inland areas.

.AVIATION...
090330Z...Coasts/Valleys...Low clouds with bases 600-1000 feet MSL

tonight. Low clouds could reach KONT from 11-14Z, though confidence
is low in ceilings. Reduced vis of 3-5 SM in HZ on higher coastal
terrain and in portions of the western valleys. Scatter out expected
for all areas 17-19Z.
