Area Forecast Discussion
National Weather Service San Diego CA
933 AM PDT Tue Sep 7 2021
.SYNOPSIS...
Above average high temperatures will continue for inland areas.
Monsoonal moisture in southeast flow aloft will bring a slight
chance of afternoon thunderstorms in the mountains and deserts for
Thursday and Friday. The marine layer will become shallower with
warming for the valleys Wednesday through Friday. A weak trough
of low pressure moving inland to the north will bring inland
drying for the weekend into early next week with some cooling for
the valleys.
&&
.DISCUSSION...FOR EXTREME SOUTHWESTERN CALIFORNIA INCLUDING ORANGE...
SAN DIEGO...WESTERN RIVERSIDE AND SOUTHWESTERN SAN BERNARDINO
COUNTIES...
This morning...The coastal eddy persists but weaker than
yesterday. The marine layer is a little shallower and low clouds
do not extend as far inland. The clearing should progress in
similar fashion to yesterday, with clouds and fog dissipating by
11 am but lingering at some beaches into the afternoon. Some
portions of the lower deserts will likely be warmer due to a
decrease in low-level moisture.
The coastal eddy will dissipate allowing the marine layer to become
shallower on Wednesday and Thursday and bringing warming for the
coast and valleys. The temperature increase will be more noticeable
in the inland valleys, and high temperatures for the Inland
Empire will likely reach the upper 90s to 104 on Thursday.
We continue to have consensus across deterministic and ensemble
model platforms with respect to the evolution of the synoptic
pattern. The upper level high centered over Nevada/Utah will drift
to the southeast, becoming centered near the Four Corners on
Thursday with an east-west ridge axis to our north. This shift in
position will allow more deep-layer moisture to reach SoCal and
the atmosphere to become less stable. This will bring a slight
chance for afternoon thunderstorms to the mtns and deserts. The
additional moisture could also have a moderating effect on
temperatures in the lower deserts, especially on Thursday. The
shift in the position of the high will allow temperatures in the
high deserts to decrease somewhat on Thursday as heights fall.
Heading into the weekend, the pattern becomes more zonal with the
high being displaced farther south as a trough of low pressure
moves inland to the north. This will bring drying, beginning
Friday and continuing into early next week. There may still be
enough moisture for some thunderstorms in the mountains and
deserts Friday afternoon.
The passage of the trough will allow the marine layer to slowly
deepen, with a slow cooling trend for the valleys developing over
the weekend and continuing into the middle of next week.
