Remember it well. I was working in Buffalo and commuting by single engine aircraft. I left Buffalo to return home for the week on the day the storm started, which was a Thursday. Took off from Buffalo airport around 4:30pm and snow was falling so hard that visibility had dropped to a 1/4 mile (so much that BUF tower couldn't see the intersection of the runways and pilots couldn't see the tower). Most arriving aircraft were just starting to be put into holds in the hopes that the visibility would improve to approach minimums.
The air temperature on the ground was above freezing but the air temperature at about 3,000 feet was way below freezing (which was the reason for the storm - extremely cold Canadian air flowing perfectly over the length of warm Lake Erie). This resulted in a very tense moment for me whereby the falling snow melted into water on the wings during taxi and then froze up to become ice covered wings at 3,000 feet.
Fortunately the snow band that was literally crushing Buffalo at that point was only about 30 miles wide and there was sun and normal life going on east of Buffalo, so the ice melted off the wings once I was clear of the band.
My two co-workers who were also leaving around that same point via commercial airlines were not so fortunate; they didn't get home until very early Sunday morning, or about two and a half days later. One of them told me later that the Northwest flight that was to become his departing flight was struck by lightning as it made its approach into Buffalo during the storm, which started his long string of delays. For those not familiar with US Great Lake-induced weather, the precipitation that falls within the atmosphere downwind of the Great Lakes during a lake-enhanced storm can be so intense that lighting is generated due to all that friction. "Thundersnow" is a common forecast during early winter months.
The damage to property and trees from the approximately two feet of very wet snow that fell in those 24 hours was devastating to the region.
