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

Easterly offshore flow continues today with wind gusts near 25-40
MPH across the mountains and foothills of San Diego and Riverside
Counties. High clouds this morning will slowly scatter by this
afternoon across much of the area. As skies clear and winds
weaken, Tuesday morning will make for the coolest night for many
this week. Most areas will lower into the 30s and 40s, though
areas in the 20s are expected for parts of the high desert and Big
Bear Lake region.

The weak ridge over the desert southwest will stick around into
the middle of this week with similar weather expected on Tuesday.
A trough`s passage over Northern California will increase onshore
flow and nudge temperatures down slightly near the coast with
higher level clouds expected to filter the sunshine. Temperatures
will remain near to slightly above normal with most areas in the
60s and 70s, with 50s above 5,000 feet.

Model guidance continues to be highly agreeable in a ridge of
high pressure building in strength across the western part of the
country. This will lead to a warming trend by Thursday into the
weekend with highs as much as 10 to 15 degrees above normal.
Friday and Saturday look to be the warmest days over all.
Confidence is moderate to high to see temperatures reach 80
degrees for valleys greater than 5 miles away from the coastline,
as well as high desert temperatures reaching 70 degrees. Inland
valleys will be the warmest with around a 40-70% chance to see
highs reach 85 degrees for northern Orange County, the western
parts of the Inland Empire, and parts of east county San Diego.
The high may weaken by Sunday into early next week, which would
bring greater onshore flow and subtle cooling. Dry weather is
likely to prevail this week into much of next week.
