...Long awaited heavy snow to arrive over the Central Rockies late this
week...

...Cool temperatures and light snow expected for parts of the Great Lakes
and Northeast over the next few days...

...Heavy snow possible across parts of the Sierra Nevada and Intermountain
West Wednesday night through Thursday...

An active weather pattern will culminate in the development of a winter
storm over the Central Rockies/Plains towards the end of the week. A short
wave trough will spawn shallow precip in the form of light snow over parts
of the Midwest tonight before spreading out into the Lower Great Lakes,
Central Appalachians, Mid-Atlantic and up through the Northeast on
Wednesday. A stationary front draped along the Gulf coast and into the
Atlantic will bring rain showers and scattered to isolated thunderstorms
to the region through much of the Southeast and Carolina coast tonight
through Wednesday. A strong upper-level trough will bring heavy snow to
the Cascades and Sierra Nevada beginning Wednesday and continuing through
Thursday. 1-2 feet of snow are expected for the Northern Cascades while
around a foot is likely over the Sierra.

Heavy snow is then expected to spread into the Intermountain West, Central
Rockies and Front Range Wednesday night and continuing into Friday the
Rockies and Front Range. 1-2 feet with higher locally higher amounts are
likely for much of the Intermountain West and Central Rockies. Heavy snow
really kicks off across the Front range and into the Central/Northern
Plains and Upper Midwest on Friday.
