The all important and busy Thanksgiving holiday is fast approaching and it’s looking very interesting. The models are consistent and bringing some major league arctic air into the Midwest and East along with the potential of a significant snow event.

The below GFS ensemble shows the build-up of heights into Greenland and the western US and the hook-up which drives south, southeast the cold pool currently building over the Yukon and Northwest Territories.

While the next cold trough shall set-up a pretty good lake-effect early next week, the GFS later in the week and run up to Thanksgiving Day has a system sliding west-east through the Tennessee Valley which could bring the first measurable snows of the season to the big cities from DC to Boston.

GFS snow totals through the next 10 days.

In the GFS snap shots, here comes the first push of cold Friday.

2nd much larger, stronger push to start next week.

3rd in the run up to the big day late next week!
