Update:
At 9 AM, the plume of moisture from the atmospheric river has
pushed southeastward out of California into northwest Mexico and
the Desert Southwest, and a synoptic low is centered over the San
Francisco Bay. Heavy rainfall and flash flooding is ongoing
across Orange County and western portions of the Inland Empire,
and another wave of rain is moving into southern San Diego County.
Widespread rain and high elevation snow will continue today
across the whole region. Rain falling on very saturated ground
from the past few days will exacerbate flood concerns.

Previous Discussion (Issued 346 AM PST Tue Feb 6 2024)...
.SHORT TERM (Today through Thursday)...
The low pressure system near the California coast will move inland
tonight and Wednesday. Weaker low pressure systems will then move
southward along the West Coast through Friday and early Saturday
with model differences on the timing, track, and intensity of
these systems which would affect the timing, intensity, and
amounts of additional precipitation.

More widespread precipitation this morning will become more
showery and continue at times through Friday and possibly into
Saturday. There is also a slight chance of thunderstorms for this
afternoon into Wednesday morning. The snow level will lower to
around 6000 feet early this morning, then fall to around 4000 feet
for late tonight, then mostly fluctuate between 4000 and 5000
feet through Friday.

The Winter Storm Warning continues for the mountains of Riverside
and San Bernardino Mountains through this evening. With snow
levels lowering and continuing showers, a Winter Weather Advisory
has been issued for the San Diego County mountains above 5000 feet
for late tonight into Wednesday afternoon.

&&

.LONG TERM (Friday through Monday)...
Additional weak low pressure systems moving southward along the
West Coast could continue showers into Friday and possibly
Saturday. There remain timing and intensity differences with these
systems which will modulate the timing as well as the intensity
and amounts of precipitation. Dry weather will then follow into
next week with high temperatures slowly warming to around average
for the middle of next week.
