.There's a Moderate risk of excessive rainfall along coastal southern
California today...
...Heavy Snow likely over Sierra Nevada and Shasta Siskiyous in
California...
...Warming trend expected to expand across the Great Plains through
midweek...
A potent upper-level low will continue directing subtropical moisture over
much of California today. Heavy coastal and low elevation rain,
thunderstorms, heavy mountain snow and high winds are all expected from
this Atmospheric River event. Excessive Rainfall leading to Flash Flooding
is possible for much of the state today. A Slight Risk of Excessive
Rainfall (level 2/4) is in effect from Humboldt to Orange County as well
as over parts of the Sacramento Valley and along upslope portions of the
Sierra. A Slight Risk of Severe Thunderstorms is in effect for parts of
the Sacramento Valley where an isolated tornado will be possible. A
targeted Moderate Risk of Excessive Rainfall is in effect for Santa
Barbara and Ventura where heavy rainfall will focus, especially over
elevated terrain. Heavy Snow will blanket the Sierra Nevada and Shasta
Siskiyous today as well, with those mountains forecast to receive 1-3 feet
(isolated higher) of snow by Tuesday morning.
The moisture feed into California will weaken considerably and sag south
on Tuesday, but the threat of Flash Flooding will persist across southern
California, in particular. Upslope flow into the Transverse ranges will
support a renewed threat of Flash Flooding. A Slight Risk of Excessive
Rainfall is in effect from Humboldt down through San Diego County on
Tuesday mainly due to sensitive soils from today's heavy rain. Up to a
foot of additional snow accumulations with locally higher amounts are
possible over the Sierra and Shasta Siskiyous on Tuesday. Damaging wind
gusts should continue into Wednesday morning before gradually weakening.
Elsewhere, lake effect snow will come to an end this afternoon across the
Lower Great Lakes. Upper level ridging with embedded shortwave energy will
support a warming trend acrosss the Great Plains and Mississippi Valley
through midweek when anomalous temperatures are expected to reach their
peak for the week. High temperatures will be between 15-25 degrees above
average by Wednesday over much of the central U.S..
