19.8" here for Novie. 2.6" in Dec so far.

Maybe Chris could give more on it and the possibility. The cleaner your air generally the colder you have to get to produce all ice crystals, but different cloud condensation nuclei perform in different ways.

Maybe just cold enough for a little diamond dust. -13C seems a little warm for that, but I guess it’s possible with the right nuclei...especially if there are a lot of smoke related particulates trapped below the inversion on a rad cooling night.

Merry Christmas eve weenies!

Enjoy the -40s

Gene is up to 42.8 now while I've dropped back to 34.4. I loathe these winter days where we can't mix out efficiently.

Yeah...I lost the breeze briefly at my place and the temp went from 39F to 34F in a couple of minutes with a spike in RH. There's still some low 30s down here by the lakes too. The Weirs HADS site is 32.6 while Gunstock is 42. Not bad for full sun at midday.

Actually we're doing a little pre damage today to soften up the snow. Pushing low 40s at midday with full sun even in the high terrain. Kinda funny how we're still a bit inverted tanks to the lack of mixing.

It'll come down to the dews. If we mix into that 53/53 air it'll vaporize fast. I think mine will be wiped out completely and I'll agree with your call if you say you have 5" out there. If you have less on the SW side those areas may get completely wiped out too. We'll see. I really need to get my roof cleared, but I don't need over an inch of rain. I'm hoping some can soak into the ground underneath the thin pack. If it's all frozen I'm kinda screwed.

Tough call on 50F. I could see us mixing out...especially you at your elevation. You could be 50F while Plymouth airport is 37F or something. As for Alex, if he's upsloping with NW flow he'll probably downslope to some extent with SE flow. Hopefully we keep the heaviest rain for WNE.

I think he toggles his posting "source" to HTML and just pastes the code in.

22.3"

We wind.

Eh. 43F here . Not much has melted unfortunately.

What did the 7 day ens mean 2m temps have?

Widespread 50s and sun.

Quite a torch morning. 38F here with lots of sun. I see Gene up to 42F on the hill. Lots of low 40s in the high terrain up here. Then you get into S NH and you push into the U40s.

Some thaw. Some melt.

Actually I'm on the list of stations in your nearby list. CW7324 http://www.findu.com/cgi-bin/wxnear.cgi?zip=03222 And yeah, my wind is down until the snow fully melts off the roof and I get my new Davis anny and the new ultrasonic mounted up there. My mast is currently down.

Awsome Gene! Can't wait to see your obs on Mesowest. Looks like your raw obs are already up and running. Mesowest and MADIS should pick you up soon. http://www.wxqa.com/sss/search1.cgi?keyword=FW4292 http://www.findu.com/cgi-bin/raw.cgi?call=FW4292

Comfy 36F, but not much sun. The bare spots in the pack are slowly expanding.

32.5° First time above freezing in over a week.

@wxeyeNH Gene, I got to thinking. I think you can use your station on top of your roof as an anemometer transmitter. In weatherlink, set that transmitter (#1) to be an anemometer transmitter (wind). Make your new station be transmitter #2 and call that the ISS. You want your #1 transmitter to be the anemometer because it will receive the highest sampling rate. Just change the DIP switches on the 2nd transmitter to read the console. The DIP switches for #1 would be off/off/off. #2 would be off/off/on. Of course, if you want to have both stations being read by each console, then keep it as it is. This would let you have your wind up high and everything else down low though.

BBR -25F Estcourt -25F Couple more -24Fs First Lake -22F Lk Francis -21F Errol -20F Coldest I saw was -26F at Island Pond.

Sounds like your call of 2-4 flakes verified.
