Discussion

A vigorous Arctic cold front is headed our way and it is likely to generate snow showers during the mid-day and afternoon hours on Thursday along with increasing winds. There can even be a burst of heavier snow with a quick coating to an inch possible in the area by early tomorrow night. Temperatures by early Friday morning will likely bottom out in the upper single digits in many of the N and W suburbs of the Philly metro region. Before that late week Arctic air mass even has a chance to modify, another blast will be fast-approaching right on its heels. By late Saturday, a clipper system and its associated powerful Arctic front will be dropping southeastward across the Great Lakes and it is likely to generate increasing winds and snow showers around here from later Saturday into early Sunday and there can even be a period of steadier snow. The Arctic invasion that arrives here by Sunday morning will likely be the coldest of the season so far for much of the eastern US from Maine to Florida. Sunday is likely to be the coldest day here so far this winter with dangerous wind chills. The bitter cold will continue into early next week and accumulating snow is quite possible here from Tuesday into Wednesday of next week.
