RETRANSMISSION
.SYNOPSIS...
Weakening high pressure aloft and increasing onshore flow will allow
the marine layer to build slightly through the week. Night and
morning low clouds and fog will return to the coast and western
valleys, while mostly clear and warm weather prevails farther
inland. The high pressure aloft will still keep the weather warmer
than average through Saturday. Hot weather returns again early next
week as the high aloft rebuilds over the region.

.DISCUSSION...FOR EXTREME SOUTHWESTERN CALIFORNIA INCLUDING ORANGE...
SAN DIEGO...WESTERN RIVERSIDE AND SOUTHWESTERN SAN BERNARDINO
COUNTIES...
The ridge over the Southwest will flatten today and Thursday as a
trough of low pressure moves across the Pacific Northwest. This
should result in minor cooling in most areas. As a result, the Heat
Warning for the mountains has been cancelled. Today should be a
couple degrees cooler than yesterday as 500mb heights lower to 593
DM today compared to 596 DM on Tuesday. 850 mb temps will also be a
couple degrees lower. Mid and high clouds also cover the mountains
and valleys this morning. So highs in most areas will be a couple
degrees lower. The exception will be the deserts where the gulf
surge has retreated and the airmass is drier than yesterday.
Additionally, skies will be mostly sunny over the deserts today
compared to yesterday when mid level clouds were present. Therefore,
the Heat Warning will remain in effect for the deserts through 8 pm
this evening. Highs in the lower deserts will range from 110-115,
and from 100-108 in the high deserts.
Long Range outlook Sunday through Wednesday: The east-west oriented
500 mb ridge will remain over the southwestern states through
Saturday, albeit in a weaker state as it is subjected to shortwave
energy moving inland across the Pacific Northwest. The ridge is
resilient though, and it will strengthen over the Four Corners area
Sunday through Wednesday, expanding westward over So-Cal as it does.
500 heights once again climb above 595DM, and this means we will be
in for another period of hot weather early next week.
