Ginx the highest hourly report at the Danbury Airport was 98F on 7/15/95. It seems hard to believe the coop station got to 106 that day.

 

Also... BDL... everyones favorite downslope dandy torch from hell spot at a lower elevation was 100 that day.

White Plains only got to 100F as well. I'll have to go back and look at other dates. I believe DXR has hit 103+ several times, but that 1995 ob also looks suspect upon further review.

Great to see the Ansonia snowfall record become official.

http://ryanhanrahan.com/2013/05/14/its-official-ansonia-smashes-state-24-hour-snowfall-record/

A few things about it... one is that the snow was just measured the following morning... no 6-hour clearing. The second thing that's remarkable is that the liquid equivalent was 3.24". This wasn't fluff!!!

The way it should be measured. After the snow has fallen. None of that snowboard nonsense. That's what causes the lower totals

I was never a fan of the snowboard measurements unless it was a long-duration event or one where precipitation types changed multiple times. Then it's not always as black and white.

In Feb. 2006 I measured 21 and change in Danbury, but almost every other report was significantly higher. I doubt they all used the clearing technique, but I'd rather lean on conservative amounts. You always have some reports that are bloated or for whatever other reason, overdone.

I noticed through social media this winter a lot of people just guessed numbers and they were often too high. I'd like to think official spotters know better, but at the same time, the NWS has been posting more general public reports lately.

I think the 6hrly measuring/clearing method is the way to go. It puts everyone on a similar playing field. Then you can compare ratios from location to location and storm duration doesn't play a major role in the accums. The longer the storm duration the more the weight of the snow compacts upon itself due to the weight and wind. IOW, the 2nd half of a storm gets "penalized" more than the first half.

 

I think laser snow sensors will be the new trend in automated snow measurement. I may try to make my own for next winter.

105F at Torrington seems very suspicious. I'm more inclined to believe 105F at Danbury, but I haven't looked back at the 1995 setup and nearby observations to weigh in with more detail...

 

Yeah it's 106 for both... I could see how 106 is possible but based on the hourly obs at the airport and the other coop highs it really sticks out.

I always thought that max was strange. I remember looking up the DXR obs for that day once and seeing nothing close to the COOP reading. I figured it was bogus too.

 

Maybe you can get it changed? I believe Chris Burt of WU got the Libya world record 136F off of the books thanks to a little research.

Yeah Death Valley's 134 is now the world record. But I've heard that one had issues too.

From Weather Underground I just saw that Poughkeepsie had 2 hourly readings of 106F. If that's the case then I guess it's possible... I wonder if there are nearby coops in NYS that are similar?

They had that 4 day scorching stretch in 1913 with 3 130s and that's the only time they've ever been 130F+. They did pull off 129F a few times in the last 10-15 years and 128F last July. I don't think low 130s are unreasonable for there, but I won't comment on that 7/1913 stretch...I haven't seen what nearby stations reported.

MHT had 104F on 7/14, but I think they ran a good 1-2F too warm back then. ASH had 102F and CON 101F.

Did POU run a little warm back then? They had a strange jump from 102 to 106 between 2 and 3pm which seems a bit high for that time of day.

Yeah it seems odd. It's hard to see a situation where a coop (at same elevation) in a town can wind up 8F warmer than the airport station on a day where the normal torch spots (BDL and HFD) only reached 100.

Only issue with them, in my opinion, is the lack of areal averaging that you get with the ultrasonic sensors which have a much wider measurement angle which helps overcome snow surface variability. You'd probably need to build an array or a bunch of them to spread out for averaging the measured depths. The one-wire snow measurement web site has nice instructions, although a bit outdated, on how to build them.

The arrays are out there in use, but yeah, nothing for the home user yet. On the home front, some have been interfacing a Fluke414D laser range finder with a USB board from Porcupine electronics with great results.

Yeah I've never understood the reasoning behind snowboard. it causes lower totals to be measured when you do it that way. You measure the snow on the ground in various areas and take an avg of the measurements both during the snowfall and then when the snow is over
