Following the passage of a clipper system Monday into Tuesday, a new round of cold air and strong winds from the west-northwest will fuel lake-effect snow from Lakes Erie and Ontario. Conditions look to be conducive for a lake-effect snow event in this region, whereas the other Great Lakes should not deal with lake-effect snow during this time period.
The snow will start to crank up on Wednesday as a new blast of cold air from the Arctic moves in. Strong winds moving across the long axis of the lakes will lead to the development of several bands of lake-effect snow. The future radar below from the European model shows the large area of snow from the multiple lake-effect snow bands over the interior Northeast. The snow on Wednesday will be more widespread than on Thursday. Snow is likely from northeastern Ohio through Upstate New York.
On Thursday, there will be two bands: one south of Buffalo, and another near Syracuse. These two bands will fade as the day progresses on Thursday as winds shift due to a clipper system to the south.
Snow accumulations will be significant for some areas, adding up to as much as half a foot.
