I think everyone should be more concerned about the severe flooding potential by next weekend and the chance of seeing a rare t- storm in December with the possibility of more damaging straight line winds. The snow discussion can wait later. One thing at a time. The flooding potential is extremely high as the soils are frozen and completely saturated now and any heavy rainfall will runoff and flood the smaller streams immediately as they are already still at high. Mt. Holly will be playing this situation up big time in their discussion by the Thursday with flood watches going up.

This map is similar to the Euro several days ago. The Euro has reputable and repetitive natural history of being pretty much spot on ten days prior to the winter storm event in the past several years. To further expound, the weather pattern for precip this summer and fall has also been very similar to this snowfall map. It appears that just when the current weather pattern for precip this fall relaxes for a few days, the new lp bombs out somewhere along the coast. If you look at recent heavy rain events locations, the projected snowfall amounts line up pretty well with this map. The cold air will be here this time, its matter of where the LP begins to strengthen, TN Valley or gulf coast. If it is in the TN Valley, we stand a good chance in the LV and eastern PA of being wacked if the LP parks its ass at the sweet spot (Chesapeake Bay area.) My past 30 plus years doing this as a hobby- a folklore has been established for an WSW event for us, If there is an accumulating snows in either Memphis or Nashville, the cities along the piedmont and the I-81 corridor get nailed with heavy snow. How far up the piedmont with heavy snow will be the question for this storm event and whether confluence will hold the southern LP at bay especially if strengthens further south and strictly rides underneath the Canadian High out to sea. This a good storm to watch as it evolves and if I was betting man , last minute weather forecast changes maybe in order for this event for us in eastern pa. as more sampled data is ingested into the models once the pacific lp gets on shore

well the storm was a winner. I awoke this morning to thundersnow at 5:00 am in Lower Macungie Township. Thunder was pretty intense. I went to the lightning map in case any one doubted me. 3 strikes in Ancient Oaks as heavy band set up- literally puking half dollar size flakes. Total was 9 inches at the house

yes. At my house in Lower Macungie Township PA near Allentown PA at 5:00 am this morning. 3 separate strikes of lightning IT woke me up out of bed and it was vomiting snow at the time as a heavy band set up over the LV. I recorded 9 inches of snow/sleet
