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 move across the Rockies later today and then into the central Plains on Wednesday on its way to the Upper Midwest by early Thursday. This storm promises to produce significant snow from Denver to Green Bay over the next few days and there will be very strong winds on Thursday across the Upper Midwest and Great Lakes associated with the storm. 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 may even be a rumble of thunder. Much colder air will pour into the Mid-Atlantic region on Friday in the wake of the cold frontal passage and it is possible that the rain could change briefly to snow before ending early Friday. There will be a significant “lake-effect” snow event downwind of the eastern Great Lakes later Friday and this weekend, and snow shower activity could even reach the I-95 corridor on either weekend day.
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 favor 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.
