Discussion

Talk about weather whiplash...the mother of all Arctic fronts has passed through the region and temperatures will drop more than 40 degrees in some spots over the next 18 to 24 hours. Temperatures spiked up to the mid 40's just ahead of the front and will drop sharply for the rest of the day as one of the coldest air masses in twenty years floods the Mid-Atlantic region. The painful cold will last from tonight into Wednesday and temperatures will go below zero in a widespread area of the Mid-Atlantic region overnight and again late tomorrow night - and that can even include some of the big cities along the I-95 corridor. In fact, the last time New York City, Philadelphia and Washington, DC were below zero at the same time was January 19th, 1994 and there is a slight possibility of that to happen by late tonight. As we transition later this week from the brutal cold to milder conditions, there will likely be a period of snow and/or ice on Thursday night and early Friday. By the weekend, much milder conditions should return to the Mid-Atlantic region and that thaw could last for a week or so, but more big Arctic outbreaks are coming by the middle of the month.
