7:10pm a shift in the predominant weather pattern is underway for the eastern portion of the nation. Temperatures have dropped nearly 20 degrees since yesterday as a cold air mass continues to spill into the region. A storm system will be moving in on Thanks Giving day; precipitation will break out in the form of rain along the coast with pockets of freezing rain, sleet and snow across the interior valleys of the Northeast including portions of northern Pennsylvania and the southern tier of western New York State. Snow could mix in with the rain in Buffalo on Thanks Giving day as well. As this storm system passes on by, another shot of cold air will rush in behind it. This will initiate the first significant Lake Effect Snowfall of the season over the eastern shores of Lakes Erie and Ontario. For this reason, the National Weather Service has issued a Lake Effect Snow Watch which includes the city of Buffalo from Friday afternoon through Saturday. Light snow will get steadier from noon time on over the lower Great Lakes region. At this time it is rather early to pinpoint the exact locations that will receive the heaviest of the snow accumulation, the potential exists for up to 2 feet of snow in a localized area with in the most persistent snow bands which appear to be just south of Buffalo and down wind of Lake Ontario. This will be the first accumulating snow across many areas since last winter, this would be a good time to winterize your vehicle in anticipation of a potentially major accumulating snow event in western New York.
