That event, like 5/9/77, 10/10/79, and the NNJ snows of late April '83/'86, showed how climo-capricious the very early/very late snows can be. Nary a flake in my Maine foothills BY, but as we headed to IL (granddaughter #3 arrival) on the 19th we saw snow OG at both ends of I-84, shady shoulders in N.CT and the hills east of Scranton, PA. Then, 2nd day after the snowfall, we saw considerable snow in the woods along I-80 in W.PA, along with some trees broken by leaf-on accum.
Edit: Wonderful pics of 12/08; wish I some like it for 1/98 in Gardiner/AUG. THAT event was the most impactful wx of any kind I've experienced, and #2 just might be the NNJ ice storm exactly 45 years earlier. At least that 1953 storm is partly responsible for my lifelong interest in wx and trees.
12/08: I'm still not quite sure how/why MBY had the same rain (2", albeit after 4" snow) at the same 2m temps as ORH, yet escaped with 0.2" ice accretion and lots of cold puddles, but your dewpoint comment offers another clue - perhaps higher over MBY. I already think we had a thinner, if equally cold, sub-32 surface layer, so that the raindrops splashed in at less cool temps than down your way.
