Temperature tumble: Arctic air invading Northern Plains, Northeast this week
Many areas will stay below freezing for most of the week
Another arctic blast invades Midwest, Northeast this week
High temperatures in the Northeast will fall into the teens and 20s, and lows will drop into the single digits to below zero.
Another blast of arctic air will bring frigid temperatures to the Northern Plains and Northeast for most of the week.
A large dip in the jet stream will allow the colder air to invade from Canada. As a result, temperatures will struggle to stay above freezing across much of the northern United States.
Let's begin in the Northern Plains.
Forecast high temperatures on Monday.

That holds true for areas to the south, like Pittsburgh, where the city will see temperatures hover around 28 degrees on Monday.
Major cities like Boston, Providence, Rhode Island, and New York City will hover around the freezing mark on Monday.

While southern New England will enjoy a brief warmup on Tuesday, the cold temperatures will remain across much of the northern areas of the Northeast.
