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

At 1 PM, patches of low clouds were still lingering along the
immediate coast. Where those low clouds are intersecting land
visibility was under 1 mile, elsewhere skies are crystal clear.
There is still time for clearing to occur this afternoon but
patchy low clouds and fog will redevelop along the coast late
tonight into early Tuesday morning. HREF guidance is indicating a
30 to 60 percent chance of visibility 1 mile or less along
portions of the coast overnight. Low clouds and fog will likely
continue each night and morning through the week along the coast.

Warming conditions are expected through Friday as a ridge builds
overhead, the warmest locations will be the Inland Empire and lower
deserts. High temperatures will warm a few degrees each day through
Thursday for all locations. By Wednesday, high temperatures for the
valleys, mountains, and deserts will be 10 to 15 degrees above
average. Highs up to 20 degrees above average expected for Thursday
and Friday which will be the hottest days of the week. Highs west of
the mountains will be similar to Thursday or a degree or two cooler
on Friday with an additional degree or two of warming expected for
the deserts on Friday. NBM chances for Palm Springs to reach or
exceed 100 degrees is 10 percent Wednesday, 90 percent on Thursday,
and 95 percent on Friday. For Riverside chances of reaching or
exceeding 95 degrees is 25 percent Wednesday, 90 percent Thursday,
and 65 percent Friday. For the most part, HeatRisk is expected to
stay minor, with local moderate HeatRisk in the Inland Empire on
Thursday. Even with the hot daytime temperatures HeatRisk will be
limited by overnight low temperatures falling to the 50s and 60s,
which should allow for overnight relief from the heat.

By Saturday, a trough of low pressure will approach the West Coast
which will push the ridge of high pressure to our east. There
remains some uncertainty in the track of the incoming low which will
impact the temperature, wind, and cloud forecast. Current forecast
follows the NBM for Saturday through Monday which has widespread
cooling as early as Saturday with increased cloud coverage and a
slight uptick in winds over the mountains and deserts.
