How far down will this cold air on the 0Z GFS get? It will have to fight the SER.

I hate -PNAs. Wx life in the SE is so much easier with a +PNA.
I feel like I’m watching the rematch of last February .. both have shown to be worthy opponents and have shown what they can do in both December and January .. now they fight for February.

Wow this is a great sign for cold for us!

Indeed, this is likely to bust bigtime. As mentioned over the last couple of weeks, ENSO analogs like 1972, 1934, 1899, and 1895 have been suggesting that February as a whole has a good chance to end up cool to cold despite the mild first couple of days, similar to the mild first couple of days of January. And what do you know, not only did the last couple of GEFS runs turn significantly colder in the E US, the 0Z EPS did the same!

What has changed? Namely the GEFS based PNA forecast, which has trended significantly back in the positive direction overall! Also, the MJO, which is now back to the cold left side, pretty much stays within the circle on most model forecasts for the next two weeks.9BA1BE81-96CE-4ED2-BBF6-18576181DBFB.gif
