I just finished the new snowfall map with the help of several people in the office. The snowfall map is just for the storm and does not include lake-effect snowfall that will be getting organized later Tuesday and into early Wednesday downstream of the eastern lakes. Here it is....
I will get to the details later today. Brett.
From earlier today.......
Computer models trended right back to the original European model idea from several days ago showing a massive storm intensification over eastern New England starting Tuesday morning. This storm might catch a lot of people offguard as the wind and precipitation will increase rapidly during the day Tuesday.
Morning computer runs are taking the center of the nor'easter due northward through eastern New England on Tuesday and then into Quebec Tuesday night. Areas along and east of the track will be basically rain, with strong winds along the Maine coast and up into the Maritimes later Tuesday and Tuesday night.
West of the track, cold air will wrap southward from Ontario through upstate New York, changing rain over to a heavy, wet snow with strong winds. Elevation will play a key role in accumulations, and I could see over 10 inches in the Adirondacks and northern Green Mountains. Luckily, most of the leaves are gone, but we still could see downed trees and power lines in some of these areas late Tuesday and Tuesday night. Farther north in the lower areas near Cornwall and Ottawa, there will be a change to wet snow early Tuesday night, but temperatures will be above freezing and that will limit accumulations. How much? Let me look at the new model runs later this morning and I will have some answers. Looks like most of the Montreal area and points east will be mostly rain, but it will change to snow in Montreal late Tuesday night.
I will have another update this afternoon. Brett
