Icon trending towards that Monday/Tuesday overrunning potential. Mitch it’s really amazing how the models generally just follow the Ai when it comes to H5. I wouldn’t use it for temps or precip total, but man H5 is on point .
6z euro Ai drives this northern shortwave down and pumps up some overrunning ahead of it.. looks like 1-3” for many… Then a few days later it brings the ULL E This run is rain to maybe some snow, but it’s all about how SE Canada looks by then. .
I’m seeing all of the OPs generally follow the same progression as the Ai with dumping the energy out west and allowing N/S to race ahead to reinforce cold. Here is icon for example… .
It’s got potential but the damn ridge rolls over so everything is speeding up the wave. Without that happening this thing would have bombed out like some of the old GFS runs had it doing. Shame. Still, as is could back it up for a scraper at least. .
I actually thought the rgem ticked SE a bit. Btw my forecast for Philly is the following. Precip will spread into the NW burbs of Philly first. It’ll fill in once the coastal forms which is when the city should see most of its snow. 2.5-3” total. The typical NW corridor will see 4-7” with some 8-9” reports. Mostly because they get that first burst of precip. That initial banding will be fun for whoever gets under it .
I thought the end of the 18z euro looked better, but there’s nothing really going on at the surface yet, maybe too positively tilted idk. There’s some GEFs members that turn this wave into a snowstorm so we’ll see what happens at 00z .
I believe it is, the NW sections out there see the initial thump of moisture, it fills in SE with the coastal, that’s why it’s heavier out towards you guys .
That thing is locked and loaded, it’s a good compromise. I like the Ukie as a good starting point as a forecast. I think someone around like Allentown - Reading region up here could see 6-10” .
