Eastern United States experienced cold wave as temperature drops several degrees below zero. An arctic air mass passed down from Canada continues to plunge much of the U.S. into record-setting lows, continuing a punishing stretch that could result in temperatures settling 10 degrees below average for the month of February. Cold wave or arctic blast is accompanied by snow, sleet and freezing rain. There are indications that this could be some of the coldest weather since the mid-1990s for parts of the Southeast U.S., Mid-Atlantic, and central Appalachians. The coldest place in the continental U.S. was Whitefield, New Hampshire which recorded -33 degree Celsius. Schools were shut in Boston and Chicago and the National Weather Service issued a wind-chill advisory for much of the north-east. Multiple locations including Boston, New York City, Detroit, Pittsburgh, Cleveland and Chicago are likely to finish the month within the top three coldest Februaries on record. However, there is some good news for the millions of people who have had enough of the cold. Indications are that the pattern of the winds will change in the coming week so that the cold is much less severe from the Midwest to the Northeast. Temperatures from the Midwest to the Northeast will still average below normal, but they will be much less extreme. Rather than affecting the major part of the continental U.S. the pattern shift will allow frigid air to take aim more at the northern Rockies bringing relief to the majority of the population.
