The DP, on the Nam, goes from the mid 20's at midnight to the mid teens mid Monday morning...near the M/D line. Not a recipe for snow when the 2M temps are in the upper 20s mid morning.
Hard to call them all crappy when the event is 12-18 hours away. Not exactly common practice to throw out the Meso's this close. LOL. Global mania going on here. LOL.
18Z Nam is no where near S Central PA again. Not much for the Northern MA either. How many models are we ignoring now? Href, Nam, HRRR, Rap, Icon. Throw them out!
If not for the GFS and a bit of the Euro, we would probably not even be talking about this as the rest of the modeling is a nothing burger for PA. (Unless someone wanted to do some actually Met work and not model reading like I am doing today!)
