Persistent upper-level troughing in the West will contribute to an active
weather pattern for much of the country over the next couple of days. A
piece of shortwave energy will slide down the spine of the Rockies over
the coming days. This bit of energy will allow for a low pressure systems
to form, deepen and move south through the Intermountain West. Heavy snow
will develop and impact portions of the Cascades, Northern Great Basin and
Northern/Central Rockies, while light rain falls over low lying areas of
the Pacific Northwest through Wednesday. Winter Storm Warnings and
Advisories are in effect for the mountainous areas. The threat of heavy
snow will linger over the Central Rockies while simultaneously spreading
into the Front Range and Central Plains on Wednesday, where Winter Storm
Watches are in effect.

Additionally, on the backside of this system, temperatures will take a
tumble due to the arrival of very frigid air from southern Canada. This
cold airmass will plunge high temperatures across the Rockies and Plains
down into the 20s and 30s, with some isolated areas of North Dakota
failing to climb out of the single digits through the end of the week. The
cold front responsible for the dip in temperatures will tighten the local
pressure gradient leading to windy conditions across the Texas/Oklahoma
panhandle into eastern New Mexico on Wednesday. Windy and dry conditions
will contribute to a Critical Fire Weather Risk for that day. Meanwhile,
from the Deep South up into the Mid-Atlantic, a stalled out front will be
the focus for moderate to heavy rain and scattered thunderstorms over the
next couple of days. Sufficient cold air may lock into the Central
Appalachians, Mid-Atlantic and Northeast to allow for some light snow
accumulations tonight.
