An occluded boundary extended southeast from the low towards the triple point over western New York, with a warm front stretching eastward across southern New England, and a cold front racing eastward along the interior Mid-Atlantic through the Carolinas. Surface observations and RADAR indicated warm, moist air surging northward in the warm sector of the system, with rain being reported as far north as the New Hampshire/Canada border. Further west, frigid, arctic air continued to pour southeastward with an exceptionally sharp temperature gradient along the cold front tracking eastward, with temperatures dropping 15 - 25 degrees F in a matter of hours. Furthermore, northwesterly winds behind the frontal boundary continued to produce localized lake-enhanced snowfall across the Great Lakes, as synoptically-forced snow pushed northeastward into Ontario. While snowfall has waned across the northern Plains and Upper Midwest, strong wind gusts in unison with freshly fallen snow has produced ground blizzard conditions at times. ...Selected preliminary Storm Total Snowfall in inches from 700 AM CST Tue Dec 20 through 800 AM CST Thu Dec 23... ...KENTUCKY...

HARMAN 0.25 MATHIAS 0.10 SHADY SPRING 3 ESE 0.10 Areas of moderate to locally heavy snow and strong winds will continue to impact the Midwest and Upper Great Lakes today as low pressure strengthens, resulting in strong southwesterly winds producing lake-enhanced snowfall. 2-4 foot snow totals will be possible in favored snow belts through the weekend. Ahead of the potent cold front tracking eastward, moderate to heavy rain will continue across New England with a Slight Risk of Excessive Rainfall being issued across much of Maine and New Hampshire. In the wake of the cold front, frigid Arctic air will arrive over the eastern half of the country through Friday evening with high and low temperatures likely to be as much as 20 to 30 degrees below average. Blizzard conditions will persist over portions of the Plains and Midwest through Friday night with a combination of heavy snow and strong winds.
