it isn’t, but if we get that -NAO it changes things. not sure if that’s real yet… would like to see more consistency there
unfortunately, i don’t think we’ll see any consistency there
HP is in a good spot... this is why having the NW flow from the -EPO ridge is important. it's not the same as a typical Nina -PNA. LP over the 50/50 region too
what does this have anything to do with the beginning of the month? that's for late January
I agree that we may see -PNA periods mid to late month as the jet retracts, but i wouldn't say that it's favored for the whole month
a trough undercutting a -EPO is not the same pattern as a traditional -PNA. they're two different patterns. early Jan looks more like active split flow with AN heights in northern Canada... that isn't really a -PNA
February 2023 is more of a typical -PNA
i mean, you want AK and Arctic ridging to displace air, and if there is ridging in those areas, it is going to be above normal
hell, if I could have it my way, I would want the North Pole +30 degrees to get all that colder air out and into the US
