yes, this will be one of those that probably puts a few guys in the hospital for heart attacks and finger detachments. i'd clear the snow thursday morning and maybe once again during the day, just to ease exertion levels. it'll turn more powdery after noon, which is when the worst blowing and drifting will occur.
p.s. any of you with travel plans the day after christmas may want to have a back-up. there's a strong signal for another major winter storm somewhere in the midwest on the 26th, give or take a day.
