...Major winter storm to affect parts of the central U.S. and colder
weather is arriving to the East Coast...
A major winter storm is in the forecast for much of the central U.S.
extending from western Texas all the way to the Ohio Valley for this
weekend. With a large arctic high pressure area settling across the
north-central U.S. and Great Lakes region, a steady supply of sub-freezing
temperatures in the lowest levels of the atmosphere will be in place for
this region. Aloft, moist and warmer flow will be lifted above this cold
air near the surface, creating an environment favorable for widespread
freezing rain. Ice storm warnings are in effect from the Texas Panhandle
to southern Illinois, with freezing rain advisories just to the south of
the warning area. Ice amounts in excess of a half inch are possible in
some areas, which is enough to cause severe travel disruptions and power
outages. Snow is also likely on the north side of this shield of
precipitation.
After a brief spell of pleasantly mild weather for much of the East Coast
region, a sudden return to January reality is now underway and much colder
weather will return in time for the weekend. Some cities even set record
high temperatures on Thursday ahead of the cold front. By Saturday, many
of these same areas will have below normal temperatures for highs along
with the threat of some light wintry precipitation across parts of the
Mid-Atlantic region.
Elsewhere across the continental U.S., the western states will begin to
enjoy a quieter weather pattern after the recent onslaught of heavy rain
and snow. The upper level low currently near southern California will
slowly make its way towards New Mexico over the next couple of days, and
this low will be one of the factors involved in the winter storm across
the central U.S. Bitterly cold weather with subzero temperatures are
expected for the Dakotas and into Minnesota.
