Wintry Mess Slams Northeast, N. Plains

By WeatherBug Meteorologist, Chad Merrill
While the Mississippi Valley gears up for a dose of spring storms Tuesday, the Northern Plains, Minnesota Arrowhead and Northeast continue to be at the mercy of winter. A storm continues to bring snow and ice to the Northeast while the Northern Plains add on a few inches to seasonal snowfall totals.
Warm air gliding over a cold dome at the surface is producing a mixture of snow, sleet and freezing rain in central and northeastern Pennsylvania as well as southern New York while snowflakes fly from Upstate New York to southern Maine.
The snow and ice will continue overnight before the warm front exits to the northeast by Tuesday morning. Snow totals will reach 1 to 2 inches with a glaze of ice likely. Commuters along the populated Interstate 95 corridor from Boston to New York City`s western suburbs will want to allow extra time for the drive to work Tuesday morning.
Winter Weather Advisories extend from southern Pennsylvania to extreme southern Maine, including Hartford, Conn., Providence, R.I., and Boston.
Ice accumulated almost up to one-quarter inch in western Maryland with snowfall totals of one-half to 1.5 inches in northeastern Pennsylvania from this latest winter storm.
Meanwhile, a separate low pressure coming out of the Rockies is spinning moisture north where it`s meeting colder air in the Northern Plains. A stripe of snow and wintry mix is falling from the Nebraska Panhandle to northern Minnesota.
As the low moves closer, enough warm air aloft and cold air at the surface will support an icy mess in for Upper Michigan and much of Wisconsin where one-tenth of an inch of freezing rain will cause a slippery Tuesday morning commute.
Winter Weather Advisories are in effect from northern Nebraska to the Minnesota Arrowhead with Winter Storm Warnings for northern South Dakota, southeastern North Dakota and northern Minnesota. Fargo, N.D., and International Falls, Minn., are included in these advisories. Freezing Rain Advisories are in effect for Wisconsin north of Green Bay and northern Michigan.
Two to 6 inches will blanket the northern part of South Dakota while 6 to 10 inches will pummel Aberdeen, S.D., to International Falls, Minn. The low will rapidly move into Canada after daybreak Tuesday, ending the snow threat here.
Snow is nothing new for International Falls, Minn., this season. Since the start of meteorological winter in early December, 30.6 inches have accumulated which puts the seasonal snowfall total so far slightly above the average of 28.4 inches.
Farther south, a fresh low will send a strong cold front through the Mississippi Valley where destructive storms are possible. For more on the Tuesday severe weather potential, click here.
