The National Weather Service's Weather Prediction Center said an upper-level low-pressure system would develop above the Great Lakes and the Northeast at the midpoint of the week. The system could be a major snowmaker for parts of the Ohio Valley to Mid-Alantic to Northeast.

"This will result in cooler temperatures, a cold rain from the Ohio Valley to the East Coast, and early season accumulating snow for the central Appalachians and the higher terrain of the interior Northeast," NWS wrote in its latest forecast. 

Weather forecaster Joe Bastardi posted an image on X of the latest computer model, which forecast heavy snow for high elevations in the Great Lakes and interior Northeast, especially for the central Appalachians.

Here's what other meteorologists are saying... 

Models in good agreement that high elevations across the northeast will see snow Thursday-Sunday. Because temps will be pretty close to freezing, a couple degrees colder or warmer will make a big difference in snow totals. Either way, ski resorts should be happy! #mewx pic.twitter.com/JRa5jhujvc

Watching an upper-level disturbance moving from the Northern Plains to the #Northeast Wed-Fri, bringing wintry weather. #Snow swath expected from Michigan to WV, lifting into PA & New England. Timing differences exist between ECMWF (earlier) & GFS (slower). More details to come. pic.twitter.com/PhNbmLkNmO

This biggest thing in the pattern is the change in the eastern ridge which gets beaten down for the first time in months this week enough so that snow is in the forecast for elevation in the northeast. pic.twitter.com/xLR780Dz8G
