Discussion

Noticeably colder air moved into the region in the overnight hours and winds will pick up today generating very cold wind chill values. In addition, there can be a snow shower at just about anytime and anyone of these can put down a quick coating of snow given the below freezing temperatures. Another outbreak of Arctic air will arrive late tomorrow night/early Saturday morning and this blast could produce some of the lowest temperatures seen in these parts in a long time during the weekend. In fact, temperatures on both weekend days are likely to hold in the teens for highs along with wind chill values that are well below zero. In addition, low temperatures early Sunday morning are likely to drop to near the zero degree mark in the big city metro regions of DC, Philly, and New York City. If NYC actually reaches zero degrees, it’ll be the first time there in 22 years (since 1994). Boston can very well fall to 5 degrees below zero by early Sunday morning. This Arctic frontal passage late tomorrow night and early Saturday could be accompanied by snow showers and possible snow squalls with quick accumulations possible. After the brutally cold weekend, clouds will increase on Monday, President’s Day, and there is likely to be some accumulating snow by late Monday or Tuesday. It is too early to tell if this system next week rides up the coast or takes an inland track. Even if it were to take an inland track and produces a changeover from snow-to-rain, accumulating snow would still likely take place on the front end of the storm. Following the early-to-mid week storm, a break in the cold pattern is likely and we may have milder weather conditions for a period of five days or so.
