Novie is near, the first un-official month of SNE winter!

NNE looks like a decent chance for first more widespread snowfall T-Day. At least for now anyways. Still might be a bit too warm down here, but it's still early. Beyond that, the Pacific jet is real active, but with some blocking near Hudson bay, that active jet will help develop cyclogenesis at times in the East.  Hopefully one of these can work out at some point.

lol.  you have a hard time fully committing to agree with him. "I could agree", funny.

Who doesn't? LOL.  I could see it though. Will depend if enough moisture wraps around or perhaps a streamer leaking in from the Berkshires. Nothing atypical heading later into November.

It's not snow or cold, but I'm curious to see just how warm we get today. 850s are really toasty, but we sit in a bit of a col and models have an extremely shallow inversion down to around 950mb. Even though the sun angle is very low I find it hard to believe that inversion level will pan out with clear skies, no snow cover, and relatively dry ground. If we could mix up to 900mb we'd be whipping out the shorts.

46 at 930 Am here would be surprised if we get above 60-62

Well, I'm not sealing a white xmas....just mind fodder on a mild, lame Friday.

It's an active look for sure over the next few weeks.  Hopefully the area can try and cash in on at least one of these. I've heard some interesting theories on this recent pattern. It may have been MJO driven, but many are speculating that the jetstream has been anomalous in the western pacific thanks to the extreme Siberian cold. Basically clash of airmasses with strong thermal gradients helping to fuel the jet and downstream trough in GOAK area. The models overall have been too quick to break this down. I can't help but think this has something to do with it. That cold means business and has downstream effects.

I wish folks could witness it, as the meso-scale nature is pretty cool in these progged set-ups.  Like every half mile can make a huge difference.  That's why I chuckle when people talk about and remember a given winter event in which someone who got a few inches more than them *only* 10-20 miles away.  That seems like every event here. 

20 miles is a huge distance and you could see snowfall double and then decrease to zero even within those 20 miles up this way.  There are events with a 3 foot gradient over even 10-15 miles when its ripping 30-35dbz for 18 hours.

Big difference when elevation is in play, or with LES.  It's when the 10" difference in 20 miles comes during a synoptic event that we whine, especially if the cause is qpf rather than p-type.

At least the models have something interesting to conjecturize.  (I know that's not a real word...)

It's 59F right now at 4000ft MMNV1.  

Thats insane.  It's now up to 54F at MVL from 48F so maybe we are mixing it out.

From the ski resort the valley looks real hazy and you can see the inversion.

Warm season, a 59F at the summit would be mid-70s at MVL.  14-17 degree increase with normal lapse rates from 4000ft to 750ft...and that's usually what we get most of the summer.  Top is almost always 15F cooler than town as the basic rule in a mixed atmosphere.

Quite the change in 850 temps in 24 hours...from low 30s yesterday at this time to now near 60F.

Euro actually a bit too far south for T-Day. LOL. Really digs the ULL to the south. GFS-EC compromise?

 

That shortwave diving in on its heels could produce mood flakes or even some light accumulations on the weekend too...obviously just fodder at this point, but it's been kind of consistent on the models...the shortwave that is. Something to maybe look at as we get closer.

 

T-day has such marginal temps...probably an interior north of pike into NNE type deal would be my best guess for something to happen if it does at all. A scraper is probably just mostly rain for southern areas.

Yeah I was just thinking about how active it looks. Nice to see that. So while each chance might not be high, there are two storm chances I think from T-Day through that Monday-Wednesday or so.
