canderson Posted December 16, 2020 Share Posted December 16, 2020 That 3k NAM is something, alright. But I doubt any model can pinpoint where the CCB sets up. I still think it’s Altoona up to the Poconos. Link to comment Share on other sites More sharing options...
Superstorm Posted December 16, 2020 Share Posted December 16, 2020 Lancaster show 2 inches to the south and almost 30 at the NW tip. Some gradient on the nam 3k....geez. 30 mile shift and it’s boom or bust for my county if this verified. Yep, was looking at that. That would be awesome to see though..

Mixing and dryslots (or fear of), and large gradients are pretty much the norm. 1 Link to comment Share on other sites More sharing options...

People thought he was a coward for putting out a range that incredulous...it ended up being almost spot on. Our proximity to the ocean and not having a chain of mountains surrounding us can break hearts all too often. That same proximity to the big pond can pay huge dividends though, too.

Voyager Posted December 16, 2020 Share Posted December 16, 2020 I take a ride with my next door neighbor to go to Macungie to get a truckload of heating oil and come back to an I-81 mauling on the NAM's. Unbelievable!!! Link to comment Share on other sites More sharing options...

pawatch Posted December 16, 2020 Share Posted December 16, 2020 Everyone thanks for taking the time posting all the maps. And there sure hasn't been to many bad ones. Have enjoyed checking in through out the day and seeing the projected snow totals. Tractor, snowblower are ready to go. Probably another aspect of these storms that I like is sitting in front of the fireplace and watching it snow with a cup of coffee. Until it's time to go out and cleanup. After cleanup then it's time for the other liquid refreshment. 2 Link to comment Share on other sites More sharing options...

Heisy Posted December 16, 2020 Share Posted December 16, 2020 So many factors. Where does the low tuck to? Rgem/euro types almost have it to Baltimore. Lol. Then you add how quick does it deepen. 3km would be best case it really imo. Still undecided on Williamsport maybe Scranton or down in Harrisburg.
