Is everyone going to ignore the fact that the GEFS/EPS have eastern ridging with AN heights from Feb 2-10. 

The Pacific in particular looks like a disaster with a raging jet re-emerging. 

I read similiar

i just trust Mets like scooter to post these things if they were in the 10-15 day bc were constantly fed rose colored glasses of that period lately , looks like pacific flow returns w a vengeance around day 14

The mid -end first week of February should offer a storm chance even further SE in SNE

Yeah we go back to more of a -PNA look with some ridging into AK southwest to the dateline. But we also get a -NAO to try and help(although I don’t buy it yet). It’s likely an active look, but more riding the line. It’s funny how we refuse to get a classic Niño  look.

W -NAO help could be fun. Not really holding my breath on that 

as I said yesterday the next round of capitulation melts have increasing chances when this feb 7-10 onward period Is seen as crap.. but maybe first we see widespread sne storm as vortex lifts out 

And yes ....it may not go to crap, I’d give it 75/25 of doing so

What about woods? We actually have probably 70-80% cover in woods here and maybe 20-25% in open areas. Still ugly but I take the silver linings where I can get them this winter. We did have an obscene amount of qpf as sleet here though. Prob more qpf than NW in your 'hood so that might have helped keep a little more cover. 

Mostly gone.  A lot of ice from the rain that froze yesterday, but little snow

We lost several inches, but a full-coverage, several inch glacier remains. Surprisingly, even the stonewalls managed to keep snow in some areas.  Most of the deck (which I had not shoveled) melted--I'll take that as a win.

Why is it when storms show up in the 10-14 day range they rarely work out but when a warm up or cool down shows up in that period, it happens more likely than not?  Is it because warm ups  and cool downs like that usually cover a much larger percentage of the country so that has a much higher likelihood of verifying?

If we can get the blocking, that’s a good look. That’s the key. If.

This is actually somewhat (tempered) good news.  If we get an unfavorable Pacific but with a -NAO that would mean that warm surge of Pac air would stay confined to the Plains and Midwest?  So in the Northeast we could still hold onto air cold enough for it to snow.  Basically the favorable Pacific and unfavorable Atlantic would be trading places lol.  Do you think it would be a west-based - NAO?

It’s your perspective. If it warms up here it cools down somewhere else. This current cold shot gripping the country was well modeled and trended stronger. Wait until next week. As far as storms go, think about it. You’re hoping to be in the 100 mile wide sweet spot 10-14 days out. Of course that will change. That’s difficult to do. It’s why we always cringe when people are focused on a storm 10 days out. Good luck with that holding. I don’t give any model respect until it’s within 5 days or so. Too much can change and even then, I’ve seen storms appear and vanish inside 3 days.

The blocking would help keep confluence and supply of cold air into the nrn tier. It probably would not be bitter cold, but we don’t need that.

Yes, even 5 days out they're often wrong.  The most perplexing outcome though is when a model like the Euro has a storm 10 days out, loses it in the midrange and brings it back within 48 hours lol.  I wonder what causes that to happen?

No we dont, bitter cold could cause suppression!  Average cold is good enough :)  Do you think it would be a west based - NAO?

Routing hard for November 15th to be my biggest snow event this season. Makes my life so much easier with having to do snow removal at three locations. We shall see. Also OT , NG started turning gas on in Newport yesterday , with cold coming end of next week it will be a race against time to get all 6800 households turned on.

Well sometimes it’s just that guidance had the right idea originally. Maybe as it gets closer, we have some small changes in the short waves that are modeled and cause the storm to go out to sea. It only takes one or two small changes in modeling to bring that back and voila. That can happen when things are better sampled.

Thanks, it seems that it becomes much more clear when the features get on land.

Funny thing about the storm last weekend though- it was clear it would mix and even change over on the Euro even before the features came onshore.

I think any breakdown is going to be transient.  Probably will go back to something similar to what we have now by  2/12-2/14

I see a new shot of Arctic air showing up in the Northern Plains in the LR.  But what we have now is cold/dry interrupted by storms when temps spike so hopefully by then the storm track is more favorable for snow.

Yeah I could see that. Weeklies have been decent. 

I’m convinced it’s just some sort of delayed impact of the MJO.  By the time we get to 2/10 it’s probably weak 7 or none existent.  It could also just be models not wanting to establish this pattern in the long range.  I swore that 5 days ago we saw this same thing happen for a few model cycles and then it was gone.   I’ve definitely seen patterns where models consistently try to show them breaking down at day 10-15 every 5-10 days and they’re repeatedly wrong

I think the coldest wind chill I experienced was -25, I can't imagine -65. Brutal.

Coldest for me was in N. Maine, January 1982.  Temp -34 and winds 25G35 - don't have WCI table handy, but I think that's in the 65-70 range.  My company pickup, a Chevy Luv, had a heater hose engine warmer - much better than the dipstick heater - and though plugged in all night the vehicle still barely started that morning.  Oh, it was also SN- with 2 mile visibility from tiny snow grains.  Got all the way up to -14 that afternoon.
