MAV is down to -51° for MWN

MWN -29° with a 101mph peak gust.

Kinda leveling off now around 6°. Not sure if the below 0° by noon will happen.

Maybe for those who stay mixed, but there is pack and lighter winds in the Merrimack Valley so there should be some decoupling from the WAA a bit. Either way it soars Sunday morning.

@CT Rain @ORH_wxman A little nugget from the MWN observer’s discussion this morning… https://www.mountwashington.org/experience-the-weather/mount-washington-weather.aspx “This exceptionally cold airmass will have the potential to break several minimum temperature records, including Friday’s daily record of -32F, February’s monthly record of -46F, and even the all-time record of -47F.” So it sounds like they’re not recognizing the -50° reading. That reading came in their first month of records so maybe they don’t trust the validity? Not sure. They’re only using 1933-present for their extremes on their site. https://www.mountwashington.org/experience-the-weather/mount-washington-weather-archives/normals-means-and-extremes.aspx

8.7° Pathetically the new low for the season.

19° and dropping quickly. Looks like a coating of new snow from the line.

28° at 12am but maybe below zero by 12pm

Gotta look west of there.

Yeah winds ripped everywhere with that

TAN ASOS is a bit of a pit too compared to nearby stations…even on rad nights. Definitely a different feel compared to what we’ll have tomorrow night. Feb 16 will probably be worse than this down there though.

The slow GFS cave euro has been fairly steady the last few days

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.
