will be the coolest day of the week followed by a degree or two of
warming Tuesday and Wednesday. Hotter weather returns Friday through
Sunday when a ridge of high pressure builds over the Desert

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

.Morning Update...
A coastal eddy churning off the coast gave way to low clouds
pushing into the region within 20 miles of the beaches this
morning. Visible satellite shows these low clouds clearing, which
should give way to mostly clear conditions by later this morning
into the afternoon hours. Also seen is wildfire smoke infiltrating
into much of the LA Basin and Coachella Valley from two burns
occurring near the Grapevine north of Los Angeles and another near
Hesperia in the high desert. The afternoon sea breeze should help
mix the air out some, but stay safe in the smoke and warm
temperatures today across these spots.

The deepening trough to the north will bring greater onshore flow
to the region today, where inland areas will see temperatures 5 to
10 degrees cooler than yesterday. Breezy west/northwest winds will
also occur across the desert mountain slopes into the deserts with
winds near 25-40 MPH at times each afternoon and evening today and
Monday.
