End of September/Early October banter/disco.

signals to me indicate that the first week or so of October are our Indian Summer days then the bottom starts falling out, can see a falling AO/NAO combo with a rising PNA. And no Scoob not on a model. Would not surprise me in the least if snow flies inland in Oct this year again

More than a feeling you say ?

It seems most years feature flakes somewhere in interior New England...even if it's just snow showers or something. I actually feel a little skunked if I DON'T see any snowflakes by November 1.

Well considering 76% of all New England stations (160 of 210 with published snow climatology) average at least a trace of snow in October, and 91% of northern New England stations, I'd say you are right.

What does anyone think the percentage of years that the Berks see flakes in October? I gotta think a spot like Pete's or Peru sees at least a 36F snow shower most Octobers?

The probabilities of snow though are likely skewed higher from the spine of the Berks up through the Greens mores than other geographic areas at similar elevations just based on the fact that this time of year requires a good cold surge on NW winds, which orographically favors those areas to achieve the cold + precipitation combo, rather than the areas where strong CAA is a drying flow.

You are one of the most underrated posters on here, lol. Awesome stats!

I had no idea a "trace" of snow in Oct was that widespread in New England...76% of climo spots in New England averaging October snow is a lot more impressive than I'd ever imagine.

So yeah, not a bold call to say flakes will fly in the interior in October.

Now can you give the stats for 1" or greater?

ORH sees a trace or more of snow in 45% of Octobers since 1950. Berkshires above 1,000 feet would be higher and I imagine at 2,000 feet it would be something like 70% of the years.

I think I'd put the odds of the Euro's operational solution's D7-10 verifying at about 97% against. Toss it -

The ensembles definitely don't agree with it. They ahve a pretty cold northern tier...esp N plains into the N lakes...we eventually get some of it.

Number of stations with normal October snowfall of 1 inch or greater...

CT 0% (0/19)

RI 0% (0/6)

MA 2% (1/52)

SNE 1% (1/77)

VT 22% (8/37)

NH 14% (5/37)

ME 20% (12/59)

NNE 19% (25/133)

TOTAL 12% (26/210)

I forget this is not a SNE thread, well come to think of it we should title one that way as you NNE guys have one. When I say interior I mean places like Middle Ct to SNH non 2K spots, the climo for those spots is no where near 76%. Bet my life on it.

If 91% of NNE averages a trace and 76% of all of New England, I bet the probability is higher than you think Ginxy. We are only talking a trace...that's like HubbDave at 1000ft getting a 37F 3-minute 8sm snow shower. Really doesn't seem all that hard to do towards the end of October at night in a seasonably chilly pattern.

Even ORH near the Mass Pike latitude has a 50-50 shot at seeing flakes...it's just how I interpret the stats is that it's borderline likely (50%<) that NW interior spots at 800-1000ft+ see snowflakes in October.

Accumulating snow is far different as snowman showed.

PF the 1% er, like comparing our Prius or Chevy trucks to his lamborghini

LOL

My post about flakes in the interior wasn't even about my backyard after snowman showed that it's like a 90% chance in NNE climo spots...I really do think that there are parts of your BOX forecast area where I'd sort of expect flakes in October. I bet from Jaffery back to MoneyMike and Pete down into Litchfield County sees flakes more Octobers than they don't. Then it tapers to a 30-50% chance from Blizz to HubbDave...and probably drops off a cliff to quite unlikely south and east of that high terrain and in the CT Valley.
