Discussion
A vigorous upper-level low will drop southeastward across the Great Lakes on Wednesday and will help to set off the formation of a powerful coastal low along the east coast. This low will intensify on Wednesday and begin to impact the Mid-Atlantic region with significant rainfall – something that hasn’t been seen much in recent weeks. The storm will continue to intensify as it rides up along the Northeast US coastline late Wednesday into Wednesday night bringing with it heavy rainfall, strong winds and ultimately, even a change to snow in some of the higher elevations of New England. Following the storm, winds will be quite strong on Thursday in the Mid-Atlantic region and temperatures will struggle to escape the 50’s in many areas.
