2025-2026 ENSO

[40/70 Benchmark]

DJF hardly below normal from around the N shore of Boston points NE into Maine screams late-blooming Miller B, to me.

Even more pronounced for JFM:

CFS is MUCH warmer.....my stuff is seemingly a compromise of the two.

Mine is 40/18 in North Carolina. All elevation and location on the windward slopes.

Interesting! Our lows are a bit more elevated due to lots of overcast nights, though we still drop below zero several days annually.

Yeah that makes sense. Not terribly different from my avg temps. But yet another example of how snowfall is localized and very subject to other things than just the avg temp.

I wonder what a REASONABLE line or latitude is to draw a line and assume below that line is where you really need seasonable to colder than avg temps to get snow.

Based on a quick calculation, I get your DJF avg high/low as 38/20. Mine is 34/21.

Probably about 41 N.

Our lows are pretty cold because I’m in a deep, high valley (3800 feet, surrounded by 5500-6000 foot high mountains). On upslope snow days our temps get very cold also.

The flora on my property is pretty similar I’d imagine to your area. A lot of Beech, Yellow Birch, Sugar Maple and Basswood.
