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

A trough currently draped over the West Coast continues to provide
onshore flow and cooling across our region. The calendar may say
late July but temperatures across the area are more like that of
late May or early June. Widespread 70s and 80s are seen for areas
along and west of the mountains with highs nearing 100 degrees in
the lower deserts this afternoon. This troughing pattern will
dominate through the weekend with below average temperatures and
deep marine layer, leading to much of coastal basin to see low
clouds tonight into Sunday morning.

An area of high pressure across the Southern Plains will begin to
expand closer to our region, where heights will rise. This will
bring a more noticeable warming trend by Monday and Tuesday,
where temperatures will climb to seasonal averages. There is high
confidence that temperatures will go closer to 110 degrees across
the lower deserts and 90s for the IE and high desert. Confidence
lowers by the end of the week as the exact placement of the high
pressure system will determine how warm we become. For now, NBM
continues to be used to describe the latest thinking with
temperatures plateauing Tuesday into later next week. If the area
of high pressure expands further west, temperatures may need to be
increased a few degrees. Whatever occurs, moderate heat risk will
return to the lower deserts during this time period. It is summer
indeed, but make sure to take breaks if you must be outdoors!
