Our roller coaster of temperature swings will continue over the next ten days. Multiple chunks of arctic air will get pushed down from Canada into the northern and northeastern United States. Highs will bounce back and forth between the 20s, 30s and 40s, and lows will range from the single digits to around 30° over the next ten days.
The period of Sunday into Monday looks to be the coldest of the arctic blasts. There is the potential to approach record territory for the high Sunday and the low Monday morning.
