More Cold - er Weather On The Way

   Since the source of arctic air is from near or within the snow and ice covered areas of the Arctic Circle (Fig. 1), it will be very dense and very dry. As it advances south and southeast from its source region it would tend to modify as it passes across a warmer land mass beneath it.

   However, thanks to an extensive snowpack across the interior parts of the Northeast and Great Lakes States north across Southern Canada (Fig.2)  this air will modify VERY little. Thus, we can expect the very cold weather to continue into the new year. Through New Year's Day we can expect bitter cold high and low temperatures to persist averaging about 25° BELOW normal.

   In addition, whenever we have even a slight breeze or stronger expect dangerously low wind chills to occur. Such will be the case through early tonight and again later Friday into Saturday (when it will be more of stiff wind vs. a gentle breeze). We'll also have more clouds on Friday through Saturday along with the chance for some periods of light snow or snow showers as a clipper moves through. With this low's passing brisk N and NW winds will kick in later Saturday along with a re-enforcing shot bitter and frigid air moving in for New Year's Eve and New Year's Day.

   There is very little change to the temperature forecast through 2 Jan; The "relatively" warmest day will be on Saturday when temperatures will make into the teens (perhaps some 20° or low 20s south of Albany). Otherwise, daytime highs will be in the single numbers to 10° and nighttime lows well below zero.

   Last but not least...there is the chance for a snowfall next week in the Wednesday through Friday period. I am already getting messages and emails regarding this possible snowfall. All I will say is that there is a possibility for snow. As is always the case track, intensity and speed of the storm (aka duration) will determine what we get or don't get. Be prepared for a lot of postings on this possible "storm" on Facebook, Twitter, Google+ or wherever else they are posted, to.

   Remember: check the SOURCE of the post. If its just a map of some model's snowfall forecast I would discount it. ANYONE can post a map of some computer forecast model without having any knowledge of what they are posting. SHARE any posts responsibly, too. Finally, please don't ask me about what "others" are saying we're going to get. I can only speak for myself. Obviously I'll have more on this over the days to come. Hope everyone is staying warm.
