Keep it 60-62 over night. Have 4 zones in house and a jotul stove, no problem heating up areas when I need to. Same. I keep it at that temp overnight. 1 Link to comment Share on other sites More sharing options...

But as far as at this location/Ayer, there was a nor-easter in 2015 that had 12 hours of winds gusting to 50 mph in occasional milkshake white outs, at 1 F above zero! That's unfortunately countable if doing a straight up comparison. Also, there was other times in that 2015 stretch where we sustained back side advection with single digit could... So not as deep in wind chill, but close...and sustained for many hours. 2016 also had temperatures similar to this in that event, though I don't specifically recall the wind chill numbers in that. So, like I said...I give this one an edge at a regional scope. But it's debatable at this local area of N. Middl. Co whether this is the alpha romeo at in the VIP cold class. There was something about this that gave it more bite though. The low dews and wind made any exposed skin feel like it was starting to freeze instantly. I’ve had snotcicles many times before, but I was getting them last night before I even started breathing in. Shorter period of record for FIT, but this almost ran the 24hr record low dew gamut. 3 Link to comment Share on other sites More sharing options...

I think that has enough weight to be included if one is really deep diving on how cold it was / felt Only in Fort Kent. Coldest WCI, probably near -70, came on Jan 17-18, 1982. Next would be Christmas 1980; ignoring the cheap max from the previous evening, that day's temp was -16/-23 with winds 30G45. A week-plus later, Jan 3-4, 1981, was almost as brutal. CAR's -16/-27 on the 4th is their coldest max; we had closer to -20/-34, with some moderate SN at -25. Houlton had some rad and recorded -16/-41. Also, NNJ probably reached WCI near -40 early on 12/31/62, with temp -8 and winds about 50G70, strong enough to uproot large bare-limbed oaks. 1 Link to comment Share on other sites More sharing options...

I turned everything way up yesterday morning to pressurize the house and warm all the walls and concrete in the basement. My pellet stove is in the grooming rec room with registers upstairs and a fan spreading heat to the downstairs bedroom. Very comfortable sleeping at 70 while the other rooms were mid 70s 1 Link to comment Share on other sites More sharing options...

Christmas 1980 really flies under the radar with the cheap midnight high. 18° at 5z for CON, 0° at 8z, and -15° at 12z. Then eating dinner at 2pm with an afternoon high of -8°. Then it briefly went calm the following night and they reported -25° although for some reason the ob looks discounted and -19° went in the books.

We drove from Cambridge to my grandmother’s house in Dorchester and I remember the sea smoke on the bay. my dad had to let the car warm up for a long time because the brake lines were frozen. 1 Link to comment Share on other sites More sharing options...

radarman Posted February 4, 2023 Share Posted February 4, 2023 Pretty classic wave 2/wave 3 induced SSW -> descent of HP over the pole -> PV displacement event. If you were gonna draw up -10 at BOS you'd probably not put low heights in AK and onshore flow into the pac NW, but at any rate we got it done in spite of it.

Although the area has been built up quite a bit since the 50s. I’m not sure UHI matters much though when the cold is being delivered by 40kt winds. 4 Link to comment Share on other sites More sharing options...
