Hopefully, we can at least put a few inches on the ground while we still have the cold this weekend.

Yep I can see a possibility the Sun event can work out if we get the timing right with this S/W and some amplification. But it’ll be one of those deals where we probably have to wait until 72 hours out and all the features are well sampled given the very fast pattern. It could end up being suppressed again or amp more.  Would be very nice to at least get on the board for measurable snow given all this cold.

No southern stream is a killer.   Mostly little events and most with poor tracks like tomorrow.

Yeah that's in the careful what you wish for category. Normal temps this time of year are workable, anything much above slims the chances. 

[SACRUS]

22/7 off a low of 10.   Near or at freezing for highs today, sunny.  Clouds later and a mix of snow /rain into the morning.  Warmest day of the next 7 Wed with highs back into the 40s.  Arctic front brings snow/squall late Sat into Sunday.  Cold stretch Dec 11 - Dec 17 with the coldest next Mon - Wed Dec 15- 17.   Moderation to / above normal in the Dec 18 - 24 period.  Longer range showing some wetter/stormer Christmas/eve -Day but its way out there.

Not sure why cold matters on xmas-it's an indoor holiday.    Whether it's 12 or 56 you're sitting inside

The total snowfall for the week was thus 41 inches. New Haven CT received 17 inches of new snow in the storm. Up to four four feet of snow covered the ground in eastern Massachusetts following the storms. (9th-10th) (David Ludlum) (The Weather Channel)

1879" December 9th through the 10th, Chicago, Illinois: Chicago sets record highs for both 9 and 10 December, and they occur but minutes apart. During the late evening of the 9th, southerly winds bring warm air into the city. The thermometer peaks at 62 °F just before midnight and remains there into the wee hours of the 10th before a cold front brings colder temperatures that morning. (Ref. WxDoctor)

1917 - A severe winter storm struck the Ohio Valley and the Great Lakes Region. It produced 25 inches of snow and wind gusts to 78 mph at Buffalo NY.
