You raise a good point, even I saw a few flakes before Thanksgiving (first time in my life I have witnessed that). I think the main reason there is so much gnashing is because we are snow hungry, most of us are way overdue (myself included) for a major winter storm that dumps several feet of snow IOBYs.
If you think about it, the pattern goes back to LAST winter, Savannah got snow showers around St. Patrick’s Day for crying out loud (I was there). Then our summer was cooler than the last few years m and rainy, IMBY anyway, then followed up with the pattern flip at the end of October that set us up. Keep in mind, this is a LA NIÑA winter, just imagine if we had this set up with a weak El Niño...
