That is the fault of the engineering team for the different weather bureaus...running their models 4X a time (or 24X in the case of some!). That is one big pic of Brett Maher!
Did not check the UK but the Euro and CMC/Rgem seem to be in a smaller camp now in keeping the primary stronger as it climbs....the GFS has a primary push of warm air but much more Icon like with Surface features now....NAM looks more Icon like if not even more extreme and maybe too far south.
Icon is all snow for most of the LSV as it continues to focus on a coastal much earlier than other models. No precip at all in NW PA. Morning church is ok on the Icon....focuses later Sunday,
Heavy snow over most of PA at 159. High blocked the app runner and sent the low across VA. Storm 2 is a major hit but relies on a fantasy type path to get there.
1012 Low over the FL Panhandle at 141. That is one way to not get an App runner.
Edit-Ugh, inland low takes control over next 6 hours...heading up the spine.
