The OLR 5N to 5S and 160W to 160E has been consistently positive for a while now. That means the forcing on the atmosphere is basically Ninaish.

Not sure they get much precip on average in late October and early November. Billings is around 30% of normal precip for November that is a departure of -0.19 Don't think .19 matters too much.

November has been like this in recent years.. The pattern has often lead to a -PNA Winter.

I think a few places inland will get some big wind out of this. Could be general high winds along the coast as well.

MT is looking ugly right now.
