At 600 AM PST...A potent storm system that tracked eastward across
the Intermountain West has made it Lee of the Rockies, with a
central pressure of 990 mb (29.23 in Hg) over northwestern Kansas.
An occluded boundary extends southward from the low across
southern Colorado, before connecting to a cold front over central
Oklahoma, which was analyzed stretching southward into portions of
Texas. Meanwhile, a frigid arctic airmass continues to surge south
over the Northern Plains and Intermountain West, with a southward
advancing cold front being analyzed to the west of the main low,
ushering in temperatures 10-20 degrees below average behind the
front. Current surface observations and RADAR depict scattered
areas of moderate to heavy rain, freezing rain, and elevation snow
over the Intermountain West and northern Plains associated with
the storm system, with convective weather toward the South.

Heavy snowfall is expected to gradually dissipate across the
Intermountain West and shift northward toward the High Plains into
tonight. However, the most widespread and substantial impacts will
occur as the system ejects into the Central Plains today along
with a developing low-pressure center tracking eastward. This will
result in heavy snow and blizzard conditions across portions of
the Central and Northern High Plains as well as heavy freezing
rain in the Upper Midwest through Wednesday. A rather broad swath
of 12"+ of snow is forecast to fall along an axis extending from
southwestern Nebraska northward through South Dakota, North
Dakota, and eastern Montana, with localized areas potentially
receiving over 2 feet of snow, especially across southern South
Dakota. Up to 0.25" of ice, with potentially higher localized
amounts, is expected to accrue across the Midwest today and into
tonight, especially in southern Minnesota and western Wisconsin.
Travel is currently hazardous or impossible across the
Intermountain West and High Plains, where there have already been
several reported accidents associated with the winter weather. On
a longer-term scale, this storm system is forecast to spread
toward the East Coast as the low pressure continues to occlude,
bringing potential winter impacts to the northern Mid-Atlantic and
Northeast. Moderate freezing rain is currently forecast over
portions of the Mid-Atlantic, particularly in an axis extending
from northern Virginia and Maryland northward across western
Pennsylvania toward Lake Erie on Thursday morning. Toward the
north, the air will be cold enough to support another snowtorm
across portions of New England. Travel across these areas may
become dangerous or impassible. Be sure to refer to WPC to access
the latest forecasts and learn about potential impacts to your
area.
The next Storm Summary will be issued by the Weather Prediction
Center at 700 PM PST. Please refer to your local National Weather
Service office for additional information on this event.
