Ice Ice Baby December 28-29 Storm Discussion

[Lava Rock]

32.5F. Was plain rn when I left for work. No need for sand to get out of driveway, but backs roads weren't great. Met a guy backing his lumber delivery truck down Tenny Hill thinking he was going to make it up the 15% grade. I told him to wait it out at the bottom at least 30min and try again as it was starting to slowly warm up.

So latent heating works both ways. Everything trying to melt now is acting to help cool the air. I always think of it as like a conservation of thermal energy. The ice is trying to go to a higher energy state now (solid to liquid) so it needs to gain heat for the phase change…hence it’s “taking” it from the air around it.

That’s why we tend to rot at 32° so often or frequently see isothermal 0°C layers aloft. So even though the diabatic heating quickly warmed us up to 32°, the melting now is trying to help us stay there. So we’ll see how long the wedge can hold now before the cold fropa blows through later.

Foggy upon waking up this morning and we're at 39 degrees so far this morning. 

[CT Valley Snowman]

33 here and rain.  About 4 miles east it's 40-42.  

[dryslot]

IP/ZR this morning 31°F

[HIPPYVALLEY]

33° rain now, but it was quite icy this morning. Side roads were slick and sidewalks in downtown Greenfield are treacherous.

[AstronomyEnjoyer]

Dumping rain at 32.0°. Lovely.

Same here.  Fog and 33F.

Yeah we always tend to rot longer than expected at 32.2* in these scenarios

About 1/8" of ice.  32.4 degrees here at 300 feet.  Hopefully we get a few hours above freezing to eliminate any possible damage from the winds.

Still a decent pack, mine looks like Swiss cheese.

32.2F   No power,  trees bending,  road is a sheet of ice.  Thankfully we have a wood burning stove and I filled up lots of pots for water last night.  Jackery power station works great for fridge, some lights and to plug in fiber internet.  Let's see how warm we can get before fropa later!

Hanging tough at 32.5F. Waiting for the warm tongue, but maybe it doesn't get that far inland. 

[Kitz Craver]

Pack was holding up well, but I think it has ripened. Starting to go now

Certainly no lack of QPF with this thing, least around here. I was bad and didn't thaw out my stratus, so it already had about 0.40" in it before this event, but there looks to be about 1.7" total in there now.

So, roughly 1.3" from this event so far. And the radar still looks pretty healthy.

Rotting at 32.2°.

Yeah I forgot to put mine out after melting down the inch of snow the other day. I got it out there at 1230am after it had already started pouring. 

It hasn’t budged from 32.3-32.4 here for over an hour. The gutters froze up so I have water pouring over them and water getting into parts of the basement.

Hopefully we can get into the upper 30s for a bit so the driveway can melt out otherwise it’ll be unwalkable for awhile.

[wxeyeNH]

32.2F here also.   I did briefly get up to 32.5F   We have to get this ice off the trees and surfaces before this evening or we are screwed.

[Baroclinic Zone]

45/42

little snow left at this point.

Same story here with the gutters, iced over the guards so its like they aren't even there.  Lost a branch off ye olde apple tree, hoping for warmth later before it refreezes and winds get gusty.

Hanging tough down here. Maybe we erode it some down here ahead of the front, but its gonna be a grind. 3k and hrrr keep MHT in the mid 30s now. Maybe we get a quick pop to 40 along the front.

Ugh, that sucks. No gutters here, and thankfully never had flooding issues due to weather. That being said, the condensate pump for my furnace burned out last night and water started pooling in the unfinished part of the basement. I was lucky and caught it early on, but right now there's a trash bin in the basement with about a foot of water in it. Methinks a trip to Home Depot will be in the cards at some point this afternoon.

I've dropped a degree in the last hour or so from 33.8° down to 32.9°.  I don't think my driveway is going to melt out enough to avoid a complete skating rink when it gets colder again.

Quality post with helpful and interesting information, thanks.
