Winter's revenge: Arctic plunge to hold firm grip on eastern US through mid-December:
Once arctic air infiltrates the eastern United States later this week, it will hold firm through at least the middle of December and bring opportunities for snow.
Residents of the East may want to take advantage of the surge of milder air early this week to put up Christmas decorations. The days of not needing heavier jackets and saving on heating costs are coming to an end.
The arctic express will not stop after it plunges into the Midwest early this week. The cold will continue to expand eastward through the week, dramatically slashing temperatures, even down to the Florida Peninsula.
Once the cold settles in, highs will be 20-30 degrees Fahrenheit lower when compared toearly this week.
The cold is expected to spread across the South and into the Northeast at midweek, following a band of soaking rain.
As the cold air catches up with the back edge of the rain, snow may briefly fall in the higher terrain of the central and northern Appalachian Mountains Tuesday night into Wednesday morning.
Later this week, temperatures will struggle to climb much above freezing across the interior Northeast from Burlington, Vermont, to Buffalo and Albany, New York, to Pittsburgh.
Late-week highs will also range from near 40 F in Boston to the lower 40s in New York City to near 50 in Raleigh, North Carolina, and Atlanta.
In the wake of rain riding along the Gulf and Southeast coasts later in the week, the colder air will eventually seep across the Florida Peninsula. Temperatures may struggle to reach 60 in Tampa and Orlando to end the week.
Highs in early December typically range from the 30s in northern New England to a few degrees around the 50-degree mark in the mid-Atlantic to the upper 50s and lower 60s in the Carolinas and the 70s in the Florida Peninsula.
Outside of the Midwest, fierce winds are not expected to usher in the initial wave of arctic air. That will prevent AccuWeather RealFeel® Temperatures from being significantly lower.
"Unlike previous events earlier this fall, the cold arriving at midweek will be slow to leave," AccuWeather Long-Range Meteorologist Max Vido said.
"Through mid-December and potentially right up to the winter solstice (on Dec. 21), residents across the eastern U.S. will have to contend with the cold weather," he said.
Vido expects temperatures to continue to average 5-10 degrees below normal across the eastern U.S. through the middle of the month.
