Discussion
An Arctic air mass is headed to the Mid-Atlantic region for the weekend with its origins on the Siberian side of the North Pole. This Arctic blast will be directly discharged to us from eastern Canada as compared with the more conventional “northwest-to-southeast” route that has air traveling over the Great Lakes meaning there will be less chance for modification. The cold front at the leading edge of this bitter cold air mass will be quite active from late tomorrow afternoon into tomorrow night with strong support in the upper part of the atmosphere, leading to snow showers and perhaps a heavier snow squall. Small accumulations of a coating to an inch or so are likely by later tomorrow night…watch for slippery spots. In addition to the bitter cold this weekend, winds will become a major factor on both days with gusts up to 50 mph producing dangerously low wind chill levels of below zero in many locations.
