@NEG NAO closer look at the system the euro has. If we get the northern stream to dive in then it can work. The southern energy alone won’t cut it with temps
That system has no chance to be snow here. The 12z euro doesn’t even have a storm for the 5th now. We need to watch the energy diving into the trough between the 7-8th as that has potential with cold around
Yeah. Winter has been out west the last two years. A Niña like pattern will do that. Their has not been much winter outside of Maine in the east.
-pna/dateline ridge/ strong vortex is a recipe for cutters
That’s a overrunning pattern imo. A full blown Niña look would have a ridge in the Aleutians. We also have a hint of a -nao with a split flow.
This is the Niña composite for December p5
This is what I mean with the ridge moving west and establishing a cross Polar flow/-epo. All the ensembles don’t roll the ridge over which would pump the southeast ridge.
