However, this arctic blast will be short-lived because temperatures will return to seasonal averages by Wednesday afternoon.
Highs will rise into the 30s and 40s for much of the Northeast, which is typical for the middle of January. Even if temperatures hold in the 20s in portions of northern New England on Wednesday, it would be right around average for this time of year.
