In the video, we look at prospects for the coming weekend and early next week in the Northeast and Great Lakes. Also, we visit the latest version of the forecast for 2 p.m. on Oct. 10. You may recall that we looked at this date on the GFS model early this week and saw what appeared to be a heavy wet snowfall underway in central and northern Pennsylvania. If you don't recall seeing that map, let me say this: we looked at this date (Oct. 10) on the GFS model early this week and saw what appeared to be a heavy wet snowfall underway in central and northern Pennsylvania.
One feature that will affect the weekend weather will be a strengthening trough aloft that heads for the eastern Great Lakes. It will trigger showers, perhaps some thunderstorms and even waterspouts over the Great Lakes as it moves through. This prog map shows where it could be early Sunday morning:
...speculation about a snowstorm Monday or Tuesday, and one is still possible. However, timing and placement remain elusive. This map shows the GFS ensemble mean "solution" for Tuesday morning showing snow just off the New England coast. Watch this story evolve on accuweather.com all weekend.
As we look father out this month, it looks cold for the Great Lakes and Northeast (as well as deep into the South) in the middle of next week but milder the following week. This map, for next Wednesday, shows a cold flow from way north in Canada.
A few tornadoes can also occur, especially from Mississippi and Alabama to Kentucky. This map shows the areas of potential severe weather through tonight as forecast by the NWS Storm Prediction Center.
A less prominent but strengthening band of snow showers was moving southeast across Wisconsin. That feature is the one that would cause snow showers tomorrow morning in the Northeast Corridor.
On Friday, a northwesterly flow of cold air heads across the Great Lakes and into the the Northeast. By Sunday afternoon, the flow shifts dramatically to send milder air from the southern Plains toward the Northeast.
