The frigid air that marched in the other day caused a wild drop in temperature in NYC on Monday. When I went to work, it felt as though the day could have been a wet early spring day with the thermometer on top of Apple Bank behind the 72nd metro stop reading 60 degrees Fahrenheit. The next morning, the same thermometer displayed a bone chilling 5 degrees. We went from spring to arctic in 24 hours. Incredible!
