Although snowfall and snow cover is "normal" to this point, it just seem like winter has not made much of an appearance here east of the Mississippi. The graphic below shows the "normal" snow cover for the northern hemisphere to this point compared to the last 10 years. In November, we were way ahead of what promised to be an early onset of winter. That did not pan out too well! Usually snow cover breeds cold and more snow...kinda like winning breeds winning...well sorta....
But here is our below normal snow cover to this point...
Compare that to last year at this time...a bit more expansive across the lakes and northeast!
And if you are waiting for anything the next week, well I'm not too sold on any storm delivering the goods for Christmas, although there is a potential for a storm on/around Christmas Day. Here is the maximum snow cover I could find from the GFS over the next 8 days. The map below is for next Friday. Clearly the GFS sees a storm cutting to our west taking aim for a snow event through the plains and into the western lakes. It appears as if Chi-Town will be experiencing a White Christmas. In the east, you best venture to northern new England to experience any bona fide snow and that is not even a sure thing!
And to make matters worse, the teleconnections of the Arctic and North Atlantic Oscillations are forecast to stay positive for the foreseeable future. Remember, a negative AO and NAO helps hold the cold in the east and promotes east coast snow storms or at the very least, creates conditions conducive to such weather events! Here is the "mild" looking NAO through the new year. Positive and trending even more so...ouch!
The AO is no better for snow lovers...
(Please forgive my feeble attempt at doctoring an image!)
Have a great PIAA AAAA football finals week's end!

AA: It's looking like a "Green Christmas" is in store...but there still is a small possibility of some snow on/around Christmas Day.
