DM that's an anomaly map not actual values.

Understood ....SR

 

Just a hunch with euro talk

this may be the source of Tips outlook

I will let him clarify it tho 

 

color code says +12 anomaly???  --- yes???

The pink is +10 to +12. The red +8 to +10. That's how I read it anyway.

But yeah, Tip probably looked at the wrong map or meant to say anomaly.

 

Yup, my bad folks - - ha.  Sorry. Will's right.  Mixing up intervals happens to the best of us sometimes.  Still, I would argue that +2 to +4 in low RH, with a deep layer W/wsw flow is going to mix to pretty mild balm.

HPC just doesn't want to fully drop this, for the 3rd day in a row.  I wonder when the energy will be fully sampled.

I do think we still warm as evident on ensemble, but too early to say ice or cutter..but the milder wx for a day or two is coming. Afterwards, -EPO comes back big time it seems. With perhaps more troughing over the SW, at least that offers storm chances.

I would expect it would be a torturous length of time for a return to winter, as that has been the trend this year and it doesn't seem anything has been truly reshuffled.  So I go for the cutter type thing, a cold front, some cold dry weather and then a storm possibility....the 25th I'd say.

We reshuffled big time in the Pacfic. Pacific was reversed from Dec.

For the late week storm, the lead s/w has been showing up for a while and is part of the reason the second s/w gets pulled east.

The CMC is the first model to say, hey maybe the first s/w will just go to town. That's the only shot at this working out for SNE, the second one is gone.

GGEM not giving up on the lead s/w idea. Completely on it's own though, but sometimes these are the kind of events that sneak up on us, when we naïvely think the models have it figured out at 120 hours out. Below, 12z GGEM vs 12z GFS. The s/w over the midwest is the one the models have been focusing on.

I still stand by from days ago that this pattern isn't for a coastal. I would love to be proven wrong...in fact I am begging...but it blows for coastals.

You can only say it so many times. The winter of none continues. Coastals that happen on T giving or go out to sea don't count.We're talking about coastals that hit us in the winter.
