Record Breaking Cold January 3-4 & 7-8 Discussion & Observations

[FPizz]

10.4 here. Maybe I can get to 2 or so

[HailMan06]

I think it's because the core of the arctic air mass with the coldest 850s is over us during the day on Tuesday.

My thermometer is down to 5.1F here at 8 PM. Seems a little low compared to surrounding obs but hopefully it's accurate.

I was at 8F. an hour ago to 11F now, weird. Are you by the Raritan? Your reading might be lower due to cold air drainage.

[uncle W]

hard to believe we will go from single digit temperatures to rain and back to single digit readings...The last time that happened was in January 1994 I think...

Yes I am by the Raritan.  We tend to radiate very well here.  Now up to 6.9F.

I'm at 7.9 in Branchburg, so pretty close to the Raritan too

[SEC]

-2° now. Supposed to go down to -8° tonight.

[NEXtreme]

But next week, won't we be hindered by the lack of a snow pack (at least near the coast, NYC, LI), after Sun/mon warmup and rain?

That air mass is much colder then this current one even without the snow cover. Sun/mon isn't really much of a warm up. It's very brief with temps in the low to mid 40's if that. I do think we hang on to the snow cover which could make this next colder shot even colder. We shall see. Certainly not a boring start to this winter that's for sure if anything it's a memorable start.

Down to 8 here, winds not quite calm yet

[TWCCraig]

10.3

 

Been hovering around that temp for about an hour now

[nzucker]

Sitting at -5F here in the northern Poconos at elevation 1550'. Expecting to get close to -20F as I'm in a sheltered valley surrounded by 1800-1900' ridges. Dropping like a rock...high was 6F this afternoon, went below zero at dusk.

[ILoveWinter]

Down to 4.7 (was 5.1 at start of sentence), likely we go below as temp seems to be dropping 2 per hour.

 

Edit: Fell another 1.2 to 3.5.  Seems like it goes down .1 every minute or two!

[SnoSki14]

Down to 10 here, still think the lowest we get to is 3-5F though forecast is -2.

[Rjay]

9.8 North Merrick

[sferic]

10.2 Lynbrook, dropping about 1 degree an hour.

[Animal]

3 below zero or -3f in highland lakes, nj

[allgame830]

3.3 degrees

[FreeRain]

Both the bank thermometer near me and my car thermometer now say 7F.

 

 

The problem is I just bought a RadioShack wireless thermometer, I put it in my back yard away from all sources of heat, and it now says 0.8F. The question is should I return it??

[NorthShoreWx]

9 ... since 9 (pm)

[Hailstorm]

I wish I was in the single digits already but I have been stuck at 11 for the past 2 hours. Why is my temp not budging when everyone else is dropping more or less? I do have a decent north wind and dewpoint of -3.

[Snowshack]

10F .. temps hovering last four hours or so

My temp has barely dropped

 

9.9 degrees

[tim]

...@ 10 pm sitting @ 5.9* here in eastport..thats above zero..fully

expect it to go below that tonite.

[ict1523]

10 degrees in Queens.

[sferic]

9.5 now in Lynbrook

[RutgersWx92]

Already 4.0 here at 10 PM.  The cold air just takes your breath away but it's refreshing.  NWS forecasted low is now -10, which would be amazing.

[rygar]

2.2 here

[Hailstorm]

My temp has barely dropped

 

9.9 degrees

Interesting, you have way less UHI than me but have the same issue as me. Maybe the coldest 850 mb temps not dropping south yet?

[SnowGoose69]

The ridge axis is not really overhead yet. alot of places still with some wind

[ILoveWinter]

Continuing to drop like a rock, now 0.7.  Has dropped nearly 5 degrees in an hour.

[TWCCraig]

There's already decent warming in the mid levels and at the 850mb level. A lot of this cold air we have is all in the low levels so I wouldn't look at the 850mb temps. Look at the surface high. I think the problem is the winds. They're light out here, but just enough to keep us from fulling radiating. Tbh, I may seem far east enough to radiate, but it still well developed here, I do have the UHI to a tiny extent.
