Have you tried here for hourlies? https://www7.ncdc.noaa.gov/CDO/cdoselect.cmd

The -39F was on 2/16 along with the CON record of -37F. Maybe you just had a typo though.

Old scale

I put in a request for data from Limestone (and some other sites) and had no luck with beating the -52F or -54F. If you want to look at the data for the fun of it (while it's temporarily still available) here are the links.

For Maine...I know FVE had at least a -54F on 1/14/2004.

Yeah...before automation you had mainly hourly obs. MWN had all analog recording instruments and a thorough climate record so they had all of the paper charts of instantaneous obs saved. The 1-min ASOS data archive goes back to the early 2000s so if there’s a record wind chill since then you could look up those and find the precise coldest minute. You’re pretty much stuck with the hourlies before then.

The -107°F came from an observer so I presume it was an in-between hour reading considering the -44°F temp was in-between as well.

Maybe not. I just figured it was close to the record with that stretch given the -45F min and the 100mph winds.

Found an article from WMUR interviewing someone from the Mt Washington observatory and apparently the wind chill reach -107F during that Jan 2004 cold shot while the temp was -44F. And yeah, that Whiteface -114F isn't accurate. To beat those MWN numbers you need to do it with colder temps. At a certain point stronger and stronger wind magnitude only creates a negligibly lower wind chill.

You’re not kidding.

Mt Washington had a -103F on 1/16/2004.

No AURBO from MWN last night and they had 100 mile vis for awhile.

Skylar is over. Congrats on Toby though.

Maybe 3 8-hourlies is a better compromise? 8hr workdays...8hrs of sleep...8hrs of Super Bowl pregame...it all makes sense.

Isn't that the point of making it 6hrs? To allow for some compaction? I've said it before, but I don't like penalizing 1"+/hr rates on the tail end of large, long duration storms. In LES land...if you pull 20" in 12hrs, clear, and then another 20" in 12hrs, but the depth only increases another 6"....does that mean you should have 40" or 26"? If both 12hr samples had the same rates with the same amount is it fair to report it as 20" for the first 12hrs and only 6" for the last 12hr?

I'll give Pete B credit for explaining that on the air. Some here like to call him a clown for not always weenieing out, but in this instance he "gets" it and that was a nice little shout-out to Ray.

Ray's going to have to join the Pete B fan club now. He's hanging pics of him in his old HS locker as we speak.

Yeah so your clearing times really exacerbated the measuring differences. A quick 8” in 90 mins on a clear board won’t settle much. Throw that 8” on top of 20” of already existing fluff and it’s compaction city. You should document your measurements in a blog post if you haven’t already.

So the 5pm would’ve been right before the band came back through, correct?

Desperate Snow Observers of Eastern Mass.

I noticed Ray was in the low 20s yesterday evening before the band moved back through. Then he seemed to pick up a quick 6-8” in like 90 minutes with a 5”/hr in there. Most in NH were pulling 2-4”/hr in that band so my guess was that he had recently cleared before it came through so it had minimal ability to compact which gave him the quick jump to near 30”. When were your clearing times Ray?

Never trust a name with accuweather in it

3.20” from one core would be a real pita to melt down. Maybe the guy did multiple cores, but the measuring area kept filling back in. When he had 48”/3.20” he realizdd something was off, kept the w.e., and stuck the yardstick into the ground.

The ratios are one of the first things I look at on cocorahs. When I see a 7:1 when the location was rotting under a 3”/hr deformation band I don’t even try to figure it out. Tossed like a salad.
