Arctic Hounds Unleashed: Long Duration Late January Cold Snap

[WxWatcher007]

I know that we have several threads going now, and mods, if this doesn't work I won't be offended if you take it down, but we have multiple blasts of Arctic air that will produce a long duration cold snap for much of the U.S., including New England. The first burst is happening as I write in advance of our major winter storm, and models continue to show a significant period post storm of frigid lows and very cold daytime highs. 

Looking specifically at CT, while we have certainly been colder, some of the ensemble progs put us in territory of some of our longer below freezing cold snaps. I think the Tuesday through Thursday right after the departure of our storm may over perform with possible radiational cooling and a fresh snowpack. 

I am not saying the numbers below will verify exactly, but I wanted to break this out from the January tracking thread and winter storm thread because I think the anomalous cold is the foundation for the wx we're seeing in the coming week or so and worthy of dedicated discussion. 

Let loose the Arctic hounds.

Below zero here at -0.3 and still falling this morning 

[wokeupthisam]

-4.9F and windy, tough stretch for wildlife

[dendrite]

-40° in Copenhgen NY

 

You can see the -30s to -40 pretty clearly across MN, WI, MI, ON, NY on IR satellite as the snow surfaces show up green on this image.

-1.3 still falling

My VP2 had a moment where it stopped reporting for about 10 minutes.

Seeing Watertown hit -33 with a -45 WC is nuts.

-2.2

IR is always a nice way to pinpoint the weenie cold spots.

[Damage In Tolland]

-2 should do it here . 

[Prismshine Productions]

Temp still dropping... -2.6/-17/-4.2

-6/-16

3F is the low in the valley here in E CT, I hit -3F earlier in the week, so not quite as cold

[512high]

Zero for the low w/-8 wind chill. Meh

[HoarfrostHubb]

-4F here.  Meh.   But the duration of this cold is impressive.   I think it’s thread worthy.

Record for days AOB 32˚ at BOS is 16 days … this will be close. Unlike the quick cold shots in 2016 and 2023 when BOS went to -9˚ and -10˚ it might not crack 0˚ but both of those went to 50˚ within a couple of days.

Great for ice fishing. No trucks or ATVS breaking through the ice this year. My friend built himself a 5x8 Bob house. Put it out on the ice last weekend. Cut some holes in the ice and said the ice was at least 24 inches thick

Not too bad in the Sun.

This has to be the best year for ice fishing in a long time.  Early start even in my area.  I saw people on the ice in mid December which I can’t recall seeing before.

-2 / -16

Alton Bay Ice Runway (B18) should be ready once the storm passes. They're at 11" right now, and need another 1-2" to open. Once they are open this year they should be open for a while.

KART -35 ob with -53 WC

Watertown always delivers.

[dendrite]

Brimson, MN COOP just came in with -43°

[CoastalWx]

4F. Coldest this season.

[mreaves]

-12.1° and now up to -10°.

Up here, it has been solidly cold. Which you would think we would have a ton of snow by now- except most of the main storm events have been rain or drizzle. But even then, it really didn't get warm enough to melt any of the pond ice. 24-48hrs of temps in the 30s-40s does minimal damage. We started getting cold enough for pond ice by mid October and November was cold with no up and down temp swings so we just kept building ice. I think there was ice fishing by end of November, maybe thanksgiving- ish. And then Dec was cold and Jan...there is a lot of good ice this year. Snowmobiling, unfortunately, still struggling. The main storm events have mostly been rain or sleet. With the lighter snows coming as upslope or arctic frontal passages. These last 2 events up here were snow, but Bretton Woods got shadowed. The local area from Bethlehem Whitefield Jefferson Lancaster actually got 6 inches in each storm. Snowmobiling is decent now, but the natural snow cover is thin.

-2 here, I thought it was going to be windy

[WxWatcher007]

Low of -20.2 here at WXW2, the coldest temperature I've experienced. Wind chill easily in the -30s. SLK looks to have hit -29, which is a win for the GFS I think. It had temps near -30 in most recent runs. Now we wait to see how warm it gets today. I've never experienced a full 24 hour period below zero. 

Low of 3.2 at WXW1 (East Hartford, CT), coldest of the season so far. 

Definitely diamond dust in the air this morning @dendrite

Got a zoomed out vid toward the east side with the sun?

[HIPPYVALLEY]

I was still at zero at 9 AM. That’s pretty impressive.
