Three days ago here at WeatherEast I predicted our chances for a white Christmas at 22%. After observing several computer models there’s a general agreement that a low pressure will form off Cape Cod Christmas Eve throwing back a period of snow over Connecticut for several hours, making our first White Christmas in eight years. The mantle of white over our landscapes will last through New Years Day as temperatures plummet through next week with a couple of more chances of snow later in the week. For now I’m calling for 2-4 inches of snow on the ground Christmas morning. I’ll make one more pass on this latest development Sunday.
