...Dynamic storm system to bring heavy snow, excessive rainfall and severe
weather from California to the Midwest...

...Heavy snow likely over the Cascades and Northern Rockies beginning
tonight...

...The East warms up while the West remains cooler than average...

Waves of upper-level energy will support hazardous weather across the West
and central U.S., while ridging in the Southeast will promote warmer than
normal temperatures to take hold in the East. An anomalous low pressure
system will continue to produce heavy rainfall and thunderstorms over
portions of southern California where a Slight Risk of excessive rainfall
is in effect for today. This system will also shift its focus of heavy
snowfall to portions of the central/southern Sierra Nevada and
Transverse/Peninsular Ranges, where Blizzard Warnings are in effect for
today. Additional accumulations of around a foot of snow are likely with
locally higher amounts possible. Expect continued impacts to travel and
infrastructure. Snow and strong winds will then shift into the Great
Basin, Southern Rockies/Plains on Saturday night into Sunday before the
surface low reintensifies into a sprawling mid-latitude cyclone over the
mid-section of the country.

Widespread showers, thunderstorms and isolated to scattered severe storms
wil be possible from late Sunday afternoon into the evening from parts of
northwest Texas northward into southern and eastern Kansas, where the
Storm Prediction Center highlighted a Slight and embedded Enhanced risk
areas. High winds and dry conditions on the backside of this system from
southeastern Colorado to the Big Bend region of Texas support an Elevated
Fire Weather Outlook for Sunday. Freezing rain is likely to develop over
portions of the Upper Midwest where around a tenth of an inch may
accumulate. Some lighter freezing rain amounts are possible over parts of
the Central Appalachians as well.

A pair of Pacific storm systems will bring heavy snow to the Olympics,
Cascades and Northern/Central Rockies beginning tonight. Between 2-3 feet
are expected for the Olympics and Cascades while around a foot is likely
for parts of the Northern/Central Rockies. Troughing in the Northeast may
produce some light lake effect snow over portions of the Lower Great Lakes
this afternoon and evening. A quasi-stationary front may provide enough
forcing for some light rain and wintry precipitation to develop over
portions of the Mid-Atlantic this today.
