2/16/1943 nashua coop had -35°. That’s the coldest S NH morning on record for most sites

Boire Field radiates really well.

No idea…not on the small scale of something like peter sinks anyway.

I had this saved on my ipad. H95

Let's do this...I guess.

I was just talking about it with my coworker. I'd be kinda shocked if schools don't cancel knowing how it is today. The caveat is the morning highs swaying their judgment.

Jan 14, 1988 in spots? ORH and BDL had -30s.

Interesting note there. That must have been added to the database relatively recently. Value: -50°F Date: January 22, 1885 Location: Mount Washington Station: 14755 Status: NA Value of -50°F exceeds the previously reported all-time minimum temperature extreme of -46 on 1/8/1968. The -50°F is not yet present in NCDC's digital data files but exists on observation forms and publications in NCDC archives. The value ties with Vermont and Maine for coldest temperature recorded in the Northeast region of the United States.

They may get multiple -40 mins out of it though like in Jan 04. For giggles that 6z output of -46F @ 74kt yields a WCI of -105.7F.

First ever MOS temp of -50F in New England I presume. lol KMWN GFS MOS GUIDANCE 2/02/2023 1200 UTC DT /FEB 2/FEB 3 /FEB 4 /FEB 5 HR 18 21 00 03 06 09 12 15 18 21 00 03 06 09 12 15 18 21 00 06 12 N/X -33 -30 -50 -10 -10 TMP 4 5 4 5 -2-13-24-33-36-40-42-44-46-43-37-30-25-20-15 -8 4 DPT 2 3 4 4 -2-13-24-33-36-40-42-44-46-43-45-41-37-30-22-14 0 CLD OV OV OV OV OV BK BK BK OV OV OV OV OV SC FW FW FW SC OV OV OV WDR 26 25 25 26 28 29 30 30 30 29 30 30 30 31 31 31 31 30 29 26 25 WSP 33 38 50 59 63 63 67 64 62 61 64 71 74 81 86 87 70 61 45 40 45 P06 0 30 26 0 0 1 0 0 0 3 10 P12 33 1 1 0 10 Q06 0 0 0 0 0 0 0 0 0 0 0 Q12 0 0 0 0 0 T06 0/ 0 0/16 0/24 0/15 0/ 0 0/ 9 0/18 0/22 0/ 0 0/ 8 T12 0/19 0/24 1/14 1/22 2/ 6 POZ 1 1 1 2 2 3 3 2 0 1 1 2 2 3 3 2 0 2 2 3 4 POS 95 99 99 98 98 97 97 98100 99 99 99 98 97 97 98100 98 98 97 96 TYP S S S S S S S S S S S S S S S S S S S S S SNW 1 0 0 CIG 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 2 2 1 1 1 VIS 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 OBV FG FG FG FG FG FG FG BL BL BL BL BL BL BL BL BL BL BL BL FG FG

What is that in kevins?

I think the groundhog has it all wrong. If I woke up to a beautiful, sunny morning I'd be more inclined to cancel winter.

HRRR is -10F here late afternoon tomorrow. Laced brownies.

I have to keep my chickens in their coop for 2 straight days...haven't done that for even 1 day since somewhere in that Dec 17/Jan 18 stretch. So I'm not a fan of this either.

It may be iced in by Sunday

As usual, 1/3 goofus + 2/3 euro and call it a day

The gfs is almost as cold as the euro now. A couple degrees here and there.

Some of those random 1 ob dates look fraudulent. The only one I’d trust there is the -30° from 1955. I assume this is BOS?

Light winds and rad cooling...sure. 2m temps don't give a crap about pack when it's -30C at 925 and 35mph winds.

Pack this?

2/14/16 depths

It won't be radiational cooling.
