Discussion

An active weather pattern continues today across the Mid-Atlantic region with a cold frontal system working its way through the area this morning as low pressure heads towards New England. Heavy snow will fall from this storm later today and tonight across Northern New England following yesterday’s significant snowfall in that part of the country. Another storm will then move into the central Plains later tomorrow and it will reach the Upper Midwest by early Thursday. This storm promises to produce significant snow for parts of Iowa, Wisconsin, Michigan and Illinois late Wednesday night and Thursday along with strong winds that could gust to 50 mph at times in the Upper Midwest. By Thursday night, this same storm will push a strong cold front towards the east coast accompanied by periods of rain that can fall heavily at times and there can even be a rumble of thunder. Much colder air will pour into the Mid-Atlantic region on Friday and Friday night in the wake of the cold frontal passage. There will be a significant “lake-effect” snow event downwind of the eastern Great Lakes on Friday and Saturday and a snow shower or two could even sneak into the I-95 corridor on either of those days.

Yet another strong storm seems destined to cross the country next week in the Tuesday-Thursday time frame and it will have lots of cold air to work with. There is some disagreement amongst the computer forecast models at this time as to whether this storm will take a track towards the Great Lakes from the southern Plains or more of a "southern route" towards the Mid-Atlantic coastline. A southern route would give us the chance for snow around here by the middle of next week and is certainly possible due to expected blocking pattern in the upper atmosphere over southern Canada.
