.DISCUSSION...FOR EXTREME SOUTHWESTERN CALIFORNIA INCLUDING ORANGE...
SAN DIEGO...WESTERN RIVERSIDE AND SOUTHWESTERN SAN BERNARDINO
COUNTIES...
.SHORT TERM (Today through Monday)...
A trough of low pressure will move inland along the West Coast. A
weak coastal eddy and shallow marine layer may bring some patchy
dense fog near the coast from a little before sunrise through mid
morning. Stronger onshore flow will bring strong gusty west winds
to portions of the mountains and deserts from midday today to late
Sunday night with strongest winds Sunday afternoon into Sunday
night.
The trough will also bring cooling into Sunday with a
chance of mostly light precipitation along and west of the
mountains and in the upper deserts for Sunday into Sunday evening.
The higher resolution models show a band of warm frontal
precipitation moving across southwest California Sunday morning
with the cold front precipitation band moving across the area
Sunday afternoon into Sunday evening. The greater chances for
measurable precipitation will be for areas bordering Los Angeles
with lesser chances farther south. Greatest rainfall amounts are
expected to be on the coastal mountain slopes with one quarter to
one third inch possible of the south slopes of the San Bernardino
County mountains with amounts of a trace to one tenth inch or less
near the coast. Dry and a little warmer for Monday.
&&
.LONG TERM (Tuesday through Friday)...
High pressure aloft near the West Coast and surface high pressure
near the Great Basin will bring dry weather and a warming trend
for Tuesday through Thursday with well above average high
temperatures for Wednesday and Thursday. There will also be
periods of mostly weak gusty northeast winds near the coastal
foothills. A little cooler for Friday as another trough of low
pressure approaches the West Coast.
