It WILL get cold, but not as cold as the GFS is saying. I think this is being way overblown here. There will not be any s--- in the great lakes region, even if the GFS were to pan out, we just arent at that point yet, 850 Temps and 1000MB thickness may be there but the surface temps just arent down there yet(however it will only be a matter of a small amount of time before this occurs). The EC looks similar to the GFS in its 850 Temp plots. But 850 MB is pretty far up, and there is nothing at the surface yet to create the type of cold needed for s---. Were gonna need a bit more snowcover before we start to see REAL cold air at the surface. The PV needs to sink further south as well. I think in the Great lakes region nightime lows would be in the mid to upper 30's but the daytime highs are still going to be lower to mid 50's(possibly some upper 40's on some spots). The PV is forecast to be quite far north so this will elminate the extreme cold needed for s--- across the Great Lakes. HOWEVER, there is going to be an H5 s/w swinging across the border just north of the Great lakes, this will carry with it some very cold air, and a chance of some light precip. So i think southerh Canada has a chance at some flurries, the northern stream of the Jet will carry this into northern New England. NOW, the H5 s/w will push the colder air into New England thus allowing for this energy to combine with cold air there. This may mean that flurries or light s--- affects portions of Northern New England. At this point ill say higher elevations only but if this trough really swings in some colder air then it may be over lower elevations as well. Pretty interesting setup, had this been a few months later wed be looking at a great clipper with some very very cold air. This s/w is quite interesting as a building Omega ridge will help it to dig slightly, GFS went bazerk and dug it down into OH(thus giving them s---), however it REALLY builds that omega ridge, that IMO is overblown, and the current indicies do not support such a ridge.
