northwest through the Southern and Central Rockies, the western
edge of a frigid Arctic air mass to the northeast. National

to heavy snow to the northeast of the surface low from
east-central Colorado east into northwest Kansas and southward

extended eastward through southern Nebraska, with additional areas
of light snow to the southwest into the Oklahoma and Texas

The low pressure system is forecast to move to the northeast into
the Middle Mississippi Valley by Thursday morning, the Ohio Valley
by Thursday evening, and into the Northeast by Friday morning.
Snow currently over the Central High Plains will begin to taper
off through the evening and overnight hours Wednesday. The system
will continue to produce rain, thunderstorms, a wintry mix, and
snow across central and eastern portions of the country as it
moves to the east. Warm, moist air will flow northward from the
Gulf of Mexico ahead of the cold front. Severe weather and heavy
rainfall, including some isolated to scattered instances of flash
flooding, will be possible with the storms ahead of the front. The
flow of moisture will also persist around to the north and west of
the surface low over the colder air mass to the north, helping to
continue a swath of moderate to heavy snow from the Central Plains
northeastward through the Middle Missouri Valley, Upper
Mississippi Valley, and into the Lower Great Lakes. Snowfall
totals will generally range between 4-8 inches, with some locally
higher amounts possible. Uncertainty in amounts increases further
to the northeast over the Lower Great Lakes, though snow is still
expected. Snowfall rates may approach a heavy 1-2" per hour at
times. Gusty northerly winds will lead to some areas of blowing
snow, including for locations where the snowfall has or will soon
end. In addition, a wintry mix of rain, freezing rain, sleet, and
snow is expected to the south of the snowfall axis, particularly
from northern Missouri into northern Illinois. Bitterly cold wind
chills will continue through Wednesday night for portions of
southern Wyoming, where temperatures may feel as cold as 25 below
for some locations.
The next Storm Summary will be issued by the Weather Prediction
Center at 900 AM CST. Please refer to your local National Weather
Service office for additional information on this event.
