…Rain and snow impacts across California come to an end today…

…Above average temperatures across the lower 48 into late week…

…Critical Fire Weather day over portions of the Southern High Plains on
Wednesday…

Rain and snow showers will gradually weaken across the state of California
today before coming to an end tonight. In the meantime, snow showers will
produce 6-12 inches of new snow for the Intermountain West and Central
Rockies. Surface cyclogenesis over the lee of the Rockies will support
strong west/southwesterly winds carrying dry air out of the Southwest and
into the Southern High Plains this afternoon. Thus, the Storm Prediction
Center issued a Critical Risk of Fire Weather over portions of
southeastern New Mexico into far western Texas.

The upper-level trough responsible for the unsettled weather in the West
will quickly move across the Rockies today and into the Plains by
Thursday. This will spawn a low pressure system over the Central/Southern
Plains which will tap some moisture from the Gulf of Mexico as it moves
across the Mississippi Valley. This interaction will produce rain showers
and scattered thunderstorms across the Midwest/Ohio Valley on Thursday.

Meanwhile, an upper ridge will generate temperatures that are well above
average across the Plains and Mississippi Valley today. Temperatures will
be anywhere from 20-30 degrees above average in these areas. Southerly
flow will send mild temperatures streaming into the East Coast on Thursday
ahead of the approaching low pressures system. The Florida peninsula will
remain below average temperature-wise through the end of the week.

…Heavy rain and heavy mountain snow in California are expected to become
less intense…

…A Moderate Risk of Excessive Rainfall remains in effect along portions
of coastal southern California today…

…Warming trend expected to expand from the Great Plains into the Midwest
through midweek…

Heavy rain, snow, high winds and thunderstorm impacts will gradually
diminish across California today, as the upper trough supporting them
pushes farther inland. A quasi-stationary front will be the focus for
additional heavy rainfall over southern California today. A Moderate Risk
of Excessive Rainfall leading to Flash Flooding (level 3/4) is in effect
for portions of Los Angeles and Orange Counties where between 1-3 inches
of rain are possible. Higher totals are expected along the immediate coast
and favored terrain of the Transverse Ranges. A broader Slight Risk area
(level 2/4) is in effect from Humboldt County down to San Diego, as well
as the Sacramento Valley and adjacent upslope areas of the Sierra.
Additional accumulations of 6-12 inches of snow are expected for the
Sierra, while 1-2 feet are likely over the Shasta Siskiyous today.
Persistent troughing and upsloping will support moderate to heavy snow
over the Intermountain West where generally between 6-12 inches of snow
can be expected. This snowfall is likely to continue into Wednesday and
expand in coverage into the Central Rockies.

Elsewhere, the ongoing warming trend is expected to continue across the
Great Plains and Mississippi Valley through Wednesday before moderating a
bit and resurging once again heading into the weekend. High temperatures
will be 15-25 degrees above average today and Wednesday over the Great
Plains and Mississippi Valley while mild air shift slowly into the Midwest
and East Coast. The Florida Peninsula will remain below average
temperature-wise due to a deepening upper trough in the western Atlantic.
A developing low pressure system will bring showers and thunderstorms to
the Midwest on Thursday.

…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..

…There’s a Moderate Risk of Excessive Rainfall leading to Flash Flooding
over portions of Southern California…

…Heavy Snow likely over Sierra Nevada and Shasta Siskiyous…

…Warming trend continues across Central U.S. through midweek…

A closed upper-level low will direct a plume of subtropical moisture into
California over the next few days. A low pressure system at the surface
will focus the moisture along its attendant surface fronts as it makes
it’s way into the state. Heavy Rainfall is expected for the coastal areas
as well as much of the inland valleys of northern/central California and
into the windward foothills of the Sierra beginning this evening. Some
instability will work it’s way into portions of southern California
tonight and continue into Monday morning, which will lead to the chance
for thunderstorms and increased rain rates. Thus, a Moderate Risk of
Excessive Rainfall leading to Flash Flooding (level 3/4) is in effect for
portions of Santa Barbara County tonight and expanding into Ventura on
Monday as the heavy rain drifts southward along a cold front. Slight Risks
(level 2/4) are in effect for Humboldt down to Ventura today and then
expanding down to Orange through Tuesday.

Meanwhile, heavy snow will develop over the Sierra and Shasta Siskiyous
tonight. This snowfall is expected to continue into Tuesday when the
Pacific moisture feed is likely to end. Between 2-4 feet of snow are
forecast for the Sierra and Shasta by Tuesday morning with locally higher
amounts possible. Elsewhere, a stalled out surface front will focus
showers and thunderstorms across the Florida Peninsula today. A stripe of
1-2 inches of rain is probable across central/southern portions of the
peninsula. Lake effect snow showers continue downwind of the Great Lakes
through Sunday night. An upper ridge with embedded shortwave energy will
support a warming trend across the Great Plains, Mississippi Valley and
Midwest over the next several days.
