.SYNOPSIS...
Warming conditions through the middle of the week, with the hottest
days expected to be Wednesday and Thursday for inland locations.
Conditions will return to near average west of the mountains for the
weekend into early next week, with above average temperatures
remaining in the deserts. The marine layer will become shallower for
the middle of the week, mainly impacting coastal areas, before
deepening again over the weekend.
&&
.DISCUSSION...FOR EXTREME SOUTHWESTERN CALIFORNIA INCLUDING ORANGE...
SAN DIEGO...WESTERN RIVERSIDE AND SOUTHWESTERN SAN BERNARDINO
COUNTIES...
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 additional warming for
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 degrees cooler than
Thursday across the area, with not much change into the weekend. NBM
high temperatures for the coast and valleys are forecast to 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.
