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

Visible satellite this morning was showing low clouds quickly
clearing from coastal areas at 9 AM, with high clouds moving into
San Diego County from south of the border. An upper level low
centered off the coast of northern California will weaken and move
inland tonight into Wednesday morning while high pressure aloft
centered over Arizona and New Mexico expands across southern
California. This will bring warming for today and Wednesday with not
much change for Thursday. The marine layer will become shallower and
patchy Wednesday and Thursday, keeping low clouds and fog that
develop more confined to coastal areas.

With the upper level high expanding west across Southern California
Wednesday and Thursday, above average temperatures are expected for
inland locations. Highs on Wednesday and Thursday are expected to be
5 to 10 degrees above average for inland locations. High
temperatures Wednesday and Thursday will range from the 70s near the
coast; the upper 90s to 104 for the Inland Empire; and 114 to 118
for the lower deserts. In the mountains below 5000 ft, highs are
expected to be in the mid-80 to upper 90s. Widespread moderate
HeatRisk is expected for the valleys and mountains, with widespread
major HeatRisk in the low deserts. Make sure you`re staying
hydrated, seeking shade, and avoiding strenuous activity during the
hottest parts of the day if possible.

High pressure aloft will remain over Southern California Friday into
early next week, but will weaken slightly. The weakening of the high
aloft will result in highs on Friday 3 to 5 cooler than Thursday
across the area, with not much change into the weekend. NBM high
temperatures for the coast and valleys will be up to 5 degrees below
average with the deserts around 5 degrees above average. The marine
layer will deepen Sunday through Tuesday with night and morning
coastal low clouds extending inland to the western valleys.
