Sunday's Forecast

- Friday: The cold front plunges through the Great Lakes. Rain may mix with, or changeover to wet snow in parts of Michigan early to Upstate, western and central New York, western Pennsylvania and the mountains of West Virginia later in the day into the night. Bands of lake-effect rain or snow may set up.
- Saturday: Additional snow may fall over the Adirondacks and the mountains of northern New England and West Virginia, possibly as far south as the Smoky Mountains. Some wet snow may also fall in lower elevations from New England to New York state, and Pennsylvania. Some lake-effect rain/snow may linger.
- Sunday: Some snow may persist in parts of New England, including some lower elevations.


Following closely on the heels of record warmth Tuesday, a jet stream disturbance will nosedive out of Canada into the Northeast from Halloween into the weekend.
Given the expected intensity of this upper-air disturbance and magnitude/depth of cold air plunging south, we're not simply talking about chilly rain showers, but also accumulating snow for some, and the first flakes of the season for others.
While it is far too soon to nail down specific who/when/where/how much questions, let's break down what we know.
