Why Does Snow Pack Better Near the Melting Point?

The discussion centers on the optimal conditions for packing snow to build snowmen, emphasizing that snow packs best when temperatures are above freezing. The unique properties of water, particularly its expansion upon freezing, influence how snow behaves under pressure. When temperatures are close to the melting point, applying slight pressure can cause the snow to melt slightly, allowing it to re-solidify and hold together better. Participants share personal experiences of building snowmen, noting that wetter snow, typically found near freezing temperatures, is ideal for packing, while dry snow is less effective regardless of temperature. The conversation also touches on the challenges of making snowmen in colder conditions, where snow is less sticky, and the fun memories associated with snow activities. Additionally, there is a mention of various snow types and their moisture content, with insights from snow scientists on the best conditions for snowball making and snowman construction.

I'm impressed that we had to come this far into the thread for someone to offer an actual explanation! :smile:
The post uou quoted was only 12 days after the inception of the thread. Although that was seven years ago.

Oh. *cough* I really should get a pair of glasses. I have to admit my age.

The above is a photo of a 4'6" snowman that I made today, Monday 11-10-25, in Chicago. It is the first one for this season. We had about 3" of snow overnight, but at first the snow was too cold to pack. I waited a couple hours until things warmed up above freezing around noon, and it packed very well.

Yesterday I built a snowman for the first time this millenium.

Grandkids were going stir crazy and every else was too busy or too grumpy to go outside in the first snowfall.

And what crazy weather. Nov 9, and fall still hadn't come and hte trees were still fully leaved. It must have come and gone in the middle of the night. The trees are still heavily covered in leaves even while coated in three inches of snow.

Granddaughter: "Poopah, can we build a snowman?"
Poopah: "🎵 DO YOU WANNA 🎵BUILD A SNOWMAAAAAAA—"
Granddaughter: "NO Poopah! Not THAT kind of snowman!"
Poopah: "But ... Olaf ... Frozen? ..."
Granddaughter:"No. Just a regular snowman."
Poopah (visibly deflated): "Sure, sure..."
Grandson: :muffled Kenny McCormick noises:

I don't know what it's like elsewhere, but we didn't get fall here.

The trees were still green as October turned into November. They've changed colour now, but haven't fallen. And now we've gotten walloped with a snowstorm that's left 3" of accumulation.

Now we've got fully leaved trees in bright golds, yellows and reds, laden with 3" in heavy, clinging snow.

@DaveC426913 I am still waiting to see most of the geese fly south. I don't think most of them have gone south yet. If they did, I missed them.
