Thanks Will , my only concern with a 9pm drive is being in such a remote area (western monads) where there will certainly not be plows out and if this did go to town down to 1500’ ...I’d be stuck ..huddling by the side of the road next to Jebediah Springfield’s house dodging falling branches and moon-shiners...But we shall see .  I’m looking for roads in around 2K .

What a weenie.

12z GFS didn't look quiet as good...kept most of the best lift off-shore and it shows in the QPF fields.  The coastal low looked to escape east more rather than northeast.

I think you really want to see some 1/2" QPF in 6-hr type rates to drive snow levels lower.  0.25-.33" every 6 hours may not cut it.

Gfs would do that lol

ukmet went east as well lol about 75 miles easy

GFS says severe threat this weekend!

I realize you and I are probably a rarer bird in this particular social -media's returning user ship ....  so speaking just to you - 

It's dicey ... deterministic t-storm days (kind of an oxymoron, heh) will obviously come down to handling set-ups correctly.  That's difficult in the best modeling times - now is not one of those times tho. 

Current uncertainties may be because we're entering a pattern change ... where circa Thursday through next week is just sort of growing pains in the models.. As is typically the case ... erratic behavior in the models when patterns start breaking down.  They'll go full on into a whiplash mass-field regime change... at others, collapse and regress way back like there is no change.  I think the continuity change happening at all, while at the same time, ...more than less preserving the SE height rises may be the take away.  The dailies?   Mm thunderstorms are the first thing the models will artificially trigger based upon rudimentary physical handling.  Unfortunately, the lower dependability of any facet.   

Or it could all be a false/red-herring for said change...and it's just the baseline look in between -NAO/blocking reload.  

I'm not convinced of either.  There is no doubt that the models are flirting with a warmer pattern though.  It's just a matter of the veracity ...therein, extent of it.  If I could have my druthers...  I'd love to see that D 10/11 Euro extrapolation pan out that way... seeing 20 to 21 C 850 mb plume on deep layer well mixed WSW would be something to behold after this particular week.  Just for morbid fascination - ...

This is a fantastic point and one that I didn't even think about...moreso b/c it's something I would think about more in the fall months. This extreme chaos and flopping of the models may very well be hints at a pattern change...or the models just don't have a handle on the pattern lol. Anyways...eventually climo will take over and heights will take on a more characteristic appearance and the pattern will relax. 

When I saw the setup for this weekend too I instantly thought EML potential...was disappointed to see that wasn't the case. As long as we are in this regime though we'll sneak in some threats (and maybe higher end type threats too)...perhaps not into our area but certainly PA/NY

Euro looks a bit less impressive too. I agree with PF on the 6 hourly rates. You want to see higher than what is showing for more than a coating in the 500-1500 foot range.  

The highest spots would still get some snows..like Mitch and other spots down to maybe 1200-1500 feet, but if we want to see 6"+ totals down to 1500 feet and accumulations of any kind below 1000 feet, then what the 12z runs show isn't really gonna cut it. 

That doesn't mean they are right...still wanna nowcast this given yesterday's overperformer, but it's probably good to view this with a skeptical eye...esp outside of NNE above 1500 feet.

Just looking at the Euro seems like Vermont has heavier precip late evening and as cold as last run.  It seems to be a bit less impressive for the whites.  As you are saying this is really snow for the high terrain over 1500 feet.  I now look safe from any power/tree problems.  Maybe I'll fly my drone and bring down some snow from 500 feet above  my fanny....

Regarding the commonality of snow , last time ORH saw a trace of snow in May was 1994

They had it in  2002

That was during the era where they had issues of documenting snow properly.

They had 0.7" on 5/18/02 and they also had a trace of snow on 5/6/96. But yeah, the records during both of those occurrences were suspect...the ASOS snow days outage years. 

But the archived metar codes show the snow obs even if the historical F6 data doesn't.

The 6 hourly precip was less over VT too compared to 06z run but I agree they are a pretty good spot overall. 

I would still think you get snow in the euro scenario, but probably not more than a sloppy inch or two. But again, we'll see. Euro underestimated the qpf yesterday down here by a lot as did many other models. Sometimes this time of the year we can see guidance mishandle the conveyors because of the convection and warmer profiles.

I had an inch in MHT in 2002 and the Salisbury COOP had 1". Yet CON shows only a T. I don't buy zero measurable.

Thanks Will.  If anyone looks at my camera's and weather station early tomorrow and see's that they are not updating you will know more fell than 1-2".

Agreed. Those obs dipping below 1 mile  at times do it for me. It's almost impossible to have snow at 33-34F for 2+ hours with vis a mile or less and not get measurable. 

Observer prob waited too long after it was over to measure.

As Kevin mentioned, this is probably nothing for a vast majority of people in New England and this forum.

Just a curiosity.  Probably nothing historically significant

So you are saying this may be a historically significant snow- I've got a chance!  I will post pictures if/when power is restored!

 

 

Sorry I am on my 5th cup of coffee of the day!
