I don't have the numbers for everyone else, but just doing a quick calculation for ORH since 1990, I get November 20th as average first measurable. (Obviously average first trace happens earlier) So your guesstimate range was accurate.

Maybe Chris could pull up the official averages for everyone at his finger tips. My ORH numbers include the lost 1995-2002 years when had a couple October snowfalls so they are probably different than the official ncdc numbers. (But mine will be more accurate)

With the caveat that ORH is missing the years you mentioned I have the dates for first measurable (long term average not normal):

BTV 11/7 :weenie:

ORH and CON 11/18

PWM 11/19

BDL 11/27

BOS 11/29

PVD 12/1

BTV is even a little earlier than I thought, but the mechanism for getting first measurable is likely much different between BTV and the rest.

Something like the long term average of >= 1" of snow would be best for tracking a "real" snowfall event.

BTV 11/18

CON 11/24

ORH 11/26

PWM 11/27

BDL 12/5

BOS 12/11

PVD 12/12

Nice. Thanks Chris. Yeah that ORH number is close to mine.  Even a bit earlier but I only did since 1991...long term will prob nudge slightly earlier with those 10/8/88 and 10/10/79 plus the 5 consecutive October snowfalls from 1960-1964. And the 1980s were really good for early/mid November snowfalls too.

If I threw my 1995-2002 years into your numbers it might push back the date a day  or so since those years averaged November 12th for first measurable.

Yeah that looks more in line.... not some CAA graupel snow shower that drops 0.2” at BTV and melts within the hour of stopping.  It’s still earlier than the others but a week between there and CON seems more like you’d think for “real” snow.
