Area Forecast Discussion
National Weather Service San Diego CA
903 PM PDT Wed May 22 2024

.SYNOPSIS...
After a slightly warmer day, a cooling trend with a deeper marine
layer sets in for Thursday-Saturday. Temperatures will be
significantly cooler than seasonal normals by Saturday, anywhere
on the order of 5-15 degrees cooler. There will also be chances
for patchy drizzle on Saturday. High pressure then builds in
starting Sunday, leading to a steady warming trend and a shallower
marine layer through the middle of next week.

&&

.DISCUSSION...FOR EXTREME SOUTHWESTERN CALIFORNIA INCLUDING ORANGE...
SAN DIEGO...WESTERN RIVERSIDE AND SOUTHWESTERN SAN BERNARDINO
COUNTIES...

.Evening Update...
No major forecast changes this evening as low clouds continue to
progress inland, slowly filling in the coastal basin. Low
temperatures will be within a few degrees of average tonight with
temperatures dipping up to 10 degrees below average for inland
valleys by Thursday afternoon. Friday still looks to be the
windiest day overall for mountains and deserts as a trough moves
through. There is a low to moderate chance in winds reaching 45
MPH, best chance across mountain passes and desert crests. This
trough will also bring cold temperatures Friday and Saturday.

.Previous Discussion (127 PM Wednesday)...

This afternoon and evening will see the expansion of a 500mb
trough over the Southwest US, as well as the development of a
coastal eddy overnight. The trough expansion and subsequent
strengthening of the onshore pressure gradients will lead to an
uptick in the onshore flow, with gusty west winds occurring
primarily over the mountains and deserts each afternoon and
evening through Saturday. Peak wind gusts will be in the 40 to 50
mph range, with locally higher gusts over ridgelines, below
passes, and through canyons, strongest winds currently look to
occur Friday afternoon/evening. Meanwhile, the coastal eddy will
act to re-deepen the marine layer more and more through Saturday,
so low clouds will continue to cover much of the inland valleys
and coastal areas each morning, and may last longer into the
afternoons over inland areas. By Saturday, the marine layer may be
deep enough to support patchy drizzle in spots. Highs Friday and
Saturday will also be significantly cooler than seasonal average,
generally on the orders of 5-10 degrees cooler than normal at the
coasts and in the deserts, and 10-15 degrees cooler across the
inland valleys and mountains.

Sunday will finally see the trough move eastward as high pressure
sets in. This leads to a steady warming trend through the middle
of next week, as well as a shallower marine layer each day. The
marine layer will likely be at its shallowest by midweek, though
some degree of low clouds will occur over the coasts and some of
the inland valleys every day. The lower deserts will see
temperatures rebound to the middle 90s on Sunday, with triple
digit readings occurring in many lower desert locations by
Memorial Day. Outside of the deserts, temperatures early next week
will generally be in the upper 60s to lower 70s at the coast,
middle 70s to middle 80s across inland valleys with the warmest
temperatures in the Inland Empire, and the upper 60s to near 80 in
the mountains, elevation dependent.

.AVIATION...
230400Z...Coast/Valleys/Foothills...Low clouds spreading inland,
with bases 1500-2500 ft MSL and tops to 3000 ft MSL. Low clouds
expected to spread inland to the coastal slopes by 13Z Thu morning,
obscuring higher terrain with areas of reduced VIS 1-3SM where
clouds and terrain intersect. Mostly clear in the afternoon except
for some SCT-BKN clouds with bases around 2500 ft MSL and tops to
3500 ft MSL near the beaches. Low clouds flowing inland again after
01Z Thu afternoon.

Mountains/Deserts...Clear skies with unrestricted VIS through
Thursday night. W-NW wind gusts of 20-35 kt over/east of mtns after
00z Thu afternoon, with weak-mod up/downdrafts and LLWS over/east of
the mtns.

afternoon and evening Friday through Sunday.
