Looking at the inits at h5 you'd think today was way above normal. Keep the fact that hp north mitigates warmth in mind because we're in that pattrn right now.

Very nice land-sea circulation as well if you really want to be an uber weenie. What do I mean? Well a bit of an onshore component yesterday, but at night when the air cools to well below the water temp...air flows from land to sea. Winds at Logan were NNW through most of the night. This has been a feature all week.

Do the ensembles differ from the train wreck op. GFS?

I want a negative NAO badly for my Europe trip starting next week. A fast Atlantic flow into Europe this time of the year is a lot of cold rain misery.

The ensembles sort of lost the -NAO. They trended higher with heights over nrn Europe and in AK.

Wonder what JB is thinking about the euro rolling in now through d9. Lol....

Not too drastically different from 00z out in the d10 lalaland range so I'd assume his thinking is no different. I'm still hoping for an outside shot at some frozen toward the 29th so I'm interested to see if the ens stay cooler, but the operationals and GEFS members are liking the cutter scenario.

Any other yr would have seen 50's

Yeah, to have all of New England pretty much at -1F to -2F (generally speaking, there are areas more or less than that) so far for November, while 4-5,000ft (H85) temps average normal to above is pretty cool.

I mean, we really should be seeing 50s/30s instead of highs of 38-45F and lows 15-25.

I couldn't believe with a H85 temp of -2C that it would be 17 degrees out when I woke up this morning.

I bet that at least starts as frozen for you. It's almost climo to do that now.

Mm, nope -

this ECM run is highly suspect beyond D6.5 - more so than is even normal for those time ranges. Can't see a -4SD EPO ridge WHILE the NAO is in the process of falling well below 0.0SD in every GEFs member, allowing a +3SD warm sector to run up blithely into the upper OV into NE by D9.

The L/Ws also appear to be excessively shortened not only for the time of year, but in particular given to the overall scope of geopotential gradient between middle Canada and Texas. There's like 10 isopleths curvilinearly undulating around an omega construct across the middle N/A latitudes and that just almost never happens. That much balanced mid level wind velocity would require longer wave-lengths. What that means to the dailies, who knows, but I doubt it gets to 70F at ALB in this anticipated renewal of blocking regime.

Also, D5 and 6. though far from any determinism ...I wouldn't toss out the idea of a shot of quick open wave potency zipping through 90W/40N around D6. There has been an interval of amplitude flagged several times among the various runs, and the 06z operational GFS went so far as to jolt a band of 3-7" snow from ALB to PWM around D7.5 Ripper frontogenic forcing in that solution! That solution, and a lot of others for that matter don't need very much adjusting at all to pop off a NJ model low type solution. As is, that would probably be a good bet for seeing flakes in the air either way ....maybe WINDEXy

we'll see.
