Newman Posted 2 hours ago Share Posted 2 hours ago Maybe a bit bold, but I told my family in Berks and Lehigh to expect 5-8" right now. I think 3-5" is safe, but I'm thinking there could be an outer fringe 700mb fronto band that surprises. Dual band type of precip shield. Would feel even more comfortable if I was NW of 95 if the closed 700 mb low passage was tucked closer to the coast. My fear is this tries to slip east last second just based on past PTSD lol 4 1 Link to comment Share on other sites More sharing options...

My fear is this tries to slip east last second just based on past PTSD lol I was just telling my mom that I think 3-5in is a really good call right now for Lehigh and I am suspecting that we end up with a Winter Weather Advisory when all is said and done for that exactly. Lolipops of course of localized 6-7in in spots, but I really like 3-5in for those areas. 1 Link to comment Share on other sites More sharing options...
Violentweatherfan Posted 2 hours ago Share Posted 2 hours ago 2 hours ago, Wxbear25 said: The issue is how the models are handling that initial piece of energy to hit the coastline, which is the energy that spawns that “eastern low” The models have continuously trended towards this being more meridionally oriented, and thus more closely involved with the main s/w energy, with the GFS leading the way to this point in that regard There won’t be an “eastern low” or a “western low”, at least for any extended time there’s going to be one low, and the question is how well the big chunk of energy can rein in that front running stuff 4 minutes ago, bluewave said: The GFS is the only model going negative tilt so fast so the low tucks in more near the coast. All the other guidance has the low consolidating a little further east and a slower negative tilt. The GFS is usually incorrect when its coastal low is the furthest west of all the other guidance. Sometimes the Euro does the same thing. I would probably shade toward the other guidance at this point and just broad brush the forecast to indicate that the chances for a 6”+ event near the coast are increasing and issue winter storm watches and wait until tomorrow to refine the warnings and higher end potential areas. These are two really good posts. Especially when forecasting accumulation expectations Link to comment Share on other sites More sharing options...

I’m not buying it still I’ll go down with the ship. Even if everything did come together warmer grounds / 50 degrees tomorrow totals of 20-30” probably are more like 12-16” but still wow. I’m very very interested to see how this unfolds and it’s been a very enjoyable ride of learning these model outputs with this particular set up. I told my work in Downingtown to expect 6-10" and I guess I'll ask the neighbor to help me shovel. 1 Link to comment Share on other sites More sharing options...

Newman Posted 1 hour ago Share Posted 1 hour ago I know the High End snow maps can seem like weenie bait, but as an EM met they are crucial for communicating POTENTIAL impacts. In EM, we always prepare for or are staged to respond to the worst case scenario. You never want to be caught with your fly down 3 1 Link to comment Share on other sites More sharing options...
MGorse Posted 1 hour ago Share Posted 1 hour ago Impressive model trends today so far. If the storm ends up being intense and closer to the coast, there will be a zone of intense upward motion/frontogenesis resulting in 2+ inches per hour snowfall rates. Winds will be an issue, but it may be a challenge to achieve blizzard conditions as the snow could be too wet. It will be interesting to see how this pans out. 4 1 Link to comment Share on other sites More sharing options...
snowwors2 Posted 1 hour ago Share Posted 1 hour ago From NEPWA (or whatever their acronym is)…They’ve been EXTREMELY accurate this year‼️ Bucks: Snow begins 6-9am Sunday and continues at varying rates through Monday morning.
