Lol at the difference between the radiators and non-radiators.

It’s been quite a winter for the fakiators

That’s a lot of New England

A lot of ASOS sites are pits. But the SNE radiators have been a lot more anomalously cold versus NNE in recent weeks.

And some are hilltops - FVE, CAR, AUG.  Not many in the middle.

Fake -2 for the low, subzero minima run at 13.

I’ve been keeping an eye on your posts. You’ve had some pretty good rad nights up there too. IZG has been colder than HIE and BML on many mornings.

We have a field sloping down to one side of our relatively flat yard and thick woods on the other three, so the cold air drains into the yard readily and gets caught there.

I’ve always found it so cool how slight differences in topography and siting can make a huge difference.

Snow cover as well. Later in the season when valleys melt and hills still have deep  hi temps can be 10 degrees lower up high

Deep pack raises the snow surface closer to the instrumentation too. Theoretically the sensors should be raised to keep them at 1.5-2m but no one does that.

In 2015 we were taking obs at 1m instead of 2m

It's been cold, but nothing where I have been super impressed by a single outbreak. At least one that was memorable. The radiating has been interesting. I can go down the road and watch my car thermo drop 6 degrees when I get just a tiny bit lower in elevation.

Closest was the airmass right before the big dog storm. ORH managed a single digit high. But it wasn’t anything historic like a 1994, 2004, or even Jan 2019…nevermind those crushing quick airmasses like Feb 2016/2023. 
 

It was more akin to the January 2005 blizzard airmass. Super impressive for a storm but nothing amazing from an absolute temperature standpoint.

I think a lot of it has to do with upslope flow; we've had snow almost every night for the past several days, and it makes a big difference

Yeah exactly. Just solid, long duration cold weather.

 

Every now and then I get these things pop up showing people next to the harbor ice and other events showcasing winters of yore prior to like 1940. Makes me a little sad because we boast about coyotes on the Charles River, but that's what winter was like back in the day. Kind of sucks.

I think I’m all set with the pre-1940 winters…colder but drier. Unless it’s the 1930s….lot of huge torches mixed in that decade but it did have 1933-34.

I’ll take the 1960s again though.

Feb 69 I would’ve been digging the thermometer out. lol

Yeah for sure the 60s. Just saying...wish we could have more solid winter temps.

That's a Holy Grail for many
