Don't put away those sweaters yet.

AccuWeather reports a southward plunge of the polar vortex will bring a quick blast of arctic air directed at the Great Lakes and northeastern United States during the first week of April.

"The latest indications are the core of the coldest air associated with the polar vortex will track a bit farther north and east, compared to the outlook from last week," according to AccuWeather Long-Range Meteorologist Edward Vallee.

The main thrust of cold air will aim at the Great Lakes, New England and the northern part of the mid-Atlantic.

There is still a chance the arctic air may sneak farther south at the last minute, according to AccuWeather Long-Range Meteorologist Joe Lundberg.

Highs may be in the 20s and 30s F during multiple days from western and northern New York state to central and northern New England. AccuWeather RealFeel® Temperatures can be 10-20 degrees lower than the actual temperature at times.

The duration of the cold air will be abbreviated in much of the Midwest and southern Appalachians.

"Instead of a week's worth of arctic air, there may only be three to five days, on average, where temperatures are 10-20 degrees below normal in the northern tier," Lundberg said.

Normal highs during the first week of April are in the lower to middle 50s in Minneapolis, Chicago and Boston, the upper 50s in Pittsburgh and New York City, and the 60s in Philadelphia and Washington, D.C.

As the arctic air passes over the open waters of the Great Lakes, rounds of lake-effect snow will erupt.
