As you know, the rule of thumb is once the surface low is north of our latitude, the precipitation shuts off in these situations. What could keep it going is lift generated by the 500mb low, which euro does seem to show.
This. Things look ripe after this big storm passes. Plenty of cold air and continuing energy moving into the southwest. Very Nino-like. Just a matter of how things time up and where they are located.
To somehow stay majority frozen for us we want that coastal capture by upper level energy as far south and east as we can get it. That capture will yank the low NW like the GFS shows. Combine a Midwest primary with a warm ocean and it’s really hard to keep the column below freezing.
Next week has “tragedy for many” written all over it lol. People should be setting hopes at “first flakes” or “first small accumulation” and not imagine some gaudy inland PA/NY snow totals shifted south 150 miles. But I know that’s not how we roll. I am getting increasingly concerned about flying home next Thursday evening…
It’s a needle threader though to get JUST enough ULL strength in the Plains and JUST enough spacing with the 50-50 so the coastal can turn the corner but stay offshore. But that’s the 6z solution I guess so it’s possible. Just hard.
It’s more a function of having a -PNA with monster Atlantic side blocking. Storm is jacked coming out of the Rockies and then starts to get sheared and shredded by the Atlantic blocking. Gets pushed south and then a coastal redevelopment of some kind happens. A zillion moving parts here so expect very little consistency.
