Bob I’d say the 60’s also , Arctic front blows through like todays and kicked off a week or longer of cold and snow. Very few winters it didn’t happen, I think just two in the 60’s
I hope and think by Saturday we will identify that the pattern changed today 1/14. We received info starting 12/15 that such change was 5-7 days away and lived with those delays for a month but looking like the true pattern change of a week of well below average temps with snow instead of 50’s and heavy rain.
Been talking about this 18 hour+ duration snd like others said cold up top so fluffy and dark and it could be .30/31 and we would do fine but it will be colder.
