A large area of low pressure centered over lower Michigan will slowly move eastward across the eastern Great Lakes through the end of the week. Rain and snow continues to fall across the region this afternoon. Accumulations so far have been highest across lower Michigan, western New York, and north central Pennsylvania where some locations have picked up several inches of snow.
Areas of rain and snow will continue through tonight across the region with additional accumulations possible, especially from northern Ohio, east across northern Pennsylvania and southern New York.
On Thursday, a cold front will move through early, cooling the atmosphere enough that most locations should change to all snow. A trough of low pressure will linger behind the slowly departing storm system which will keep periods of snow going throughout the day. Additional accumulations are possible.
Snow showers will continue Friday and Saturday as well, while gradually becoming more scattered. We will finally say goodbye to this system by Sunday as high pressure builds across the region. Temperatures will gradually cool through the weekend.
