Americans may be breathing a sigh of relief as finally the polar vortex seems to have ebbed and some mild weather is finally on the way this weekend. However, the latest weather reports suggest that the polar vortex may be returning. While this arctic blast is not expected to be nearly as severe as the snowpocalypse that gripped the country, chilly weather is still on the way. "Following the retreat of arctic air this weekend, waves of progressively colder air will move southward over Canada next week," AccuWeather.com Lead Long-Range Forecaster Paul Pastelok said.

Canada and the northern Midwest can expect cold air on Monday, extending as far as the lower Missisippi Valley and the Midwest on Tuesday and then heading East on Thursday. Temperatures will drop considerably in the days following. However, the cold will not rival the freeze of the polar vortex: "This next main arctic blast will not rival, nor will be as extensive as the event this past week," Pastelok said. Residents in the Ohio Valley and most of the Upper Midwest can expect temperatrues to stay above zero

However, there is bad news for the North Central and Northeast: AccuWeather is reporting that temperatures will drop below zero over much of this area due to high wind and chill from the north. Chicagoans should also brace for more wind driven lake snow. There may also be snow in the South and along the East Coast as cold air moves into a storm. Residents of these areas should prepare for the chilly weather with similar precautions in case of another drastic temperature drop.
