It is difficult to find a more comprehensive Weather Outlook anywhere else with the ability to get a local 10-day Forecast also.

This article focuses on what we are paying attention to in the next 48 to 72 hours. The article also includes weather maps for longer-term U.S. outlooks and a six-day World weather outlook which can be very useful for travelers.

First the NWS Short Range Forecast. The afternoon update can be found here if I have not updated it.

…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.
