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.

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

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.

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!

Nice!

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

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°.
