As January progresses, the PDO+ may well contribute to an increased tendency for PNA+ ridging. During the January 1950-2016 period, PDO- values coincided with PNA- troughs 62% of the time. In contrast, PDO+ values coincided with PNA+ ridges 73% of the time. So far, that hasn't been the case this January, but the fading La Niña could allow for the more typical PDO+/PNA+ pattern to develop and then take hold.

Don , the weeklies are so good , they may be hard to buy .

However the real warm up looks to fall between the 17th and 24th / with the trough back by the 25th 

But we may start and end the warmup with bookend snowstorms if the EPS is to be believed .

At this timeframe, I believe it's good that there are indications of a pattern change, especially as it's something that might be more likely on a statistical basis. Sometimes the guidance rushes such changes, so if the change occurs a few days later, that wouldn't be too surprising.

You can see how that didn't happen here...Winds were just strong enough to prevent optimal cooling...

Yep. It's incredible the difference that results w/ a 1-2mph light wind versus calm. I've always loved clear, calm radiational cooling nights with fresh snow cover. The temperature plummets. It's like having the effect of sandy soils, but an even more effective radiator of energy.

My stove was really expensive, problem iscooking splatters grease depending on what your cooking, and it's a bit** to clean so it smokes every time you light it.... boils water in about 2 min though, so that's nice 

Yeah, I can imagine that would be a problem.  Definitely a nice investment though.

I'm down to 11° here.

I posted them away . wow Chris .

They work thru week 3 .

Lete hope 3 and 4 verify this time .

 

The weeklies did a great job forecasting the -EPO/+PNA patterns during the 13-14 and 14-15 winters. The only knock against them was they didn't

see the depth of the trough in the East. But this time they have a -EPO/+PNA with a clear trough in the East. If week 3 and beyond actually verify,

then this could be the extended cold that has been missing since last winter. It will be interesting to see how things turn out.
