I went to Rundvik yesterday and decided to visit the sea. Turns out the bay is frozen. It's hard to know how far out the ice extends because satellites don't take photos this far north due to the weak sun here.
It was actually very eerie standing there in the dark since with the snow falling the white ground just kind of fuzzed together with the sky at the horizon.

Exhaust pipe condensation frozen fast and didn't melt in the sun all day. 15°F(-9C)





Low tide. The Sound isn't frozen yet. Gonna take more days like this.







Air Temp: 15° (-9C)
5000' Temps: -4°F (-20C)
Winds: Gusting from the North at 30mph
Barometer: 1035mb
Snowpack: 0







Saw 3 different flocks flying south yesterday.. They probably came from northern New England and said "skcrew this, keep going south, get into formation!"

Instant freeze. Of course. 7°F. I sprayed windex to clean the window a little and before I even wiped it turned to ice. lol Fast!

I tried the boiling water thing with air temp of 7°F. Some of it turned to snow, but you can hear some of the water falling to the ground so it all didn't instantly turn to snow. You can actually see the water falling from the cloud I made. lol


If you guys ever get a chance to try it don't pass it up. Just be careful with the boiling water not hitting you. Better when temps are below 0F

None of it turned to snow. Even in -50'C none of it turns to snow. The fog freezes in the air making an extra dense fog cloud basically, but the water still drops to the ground like you'd expect water thrown from a bucket would.

It's not like you technically see snowflakes falling when doing this..


Maybe a good analogy is, You ever see a snow squall? Looks like a fog coming in low to the ground, sometimes not the typical snowflakes falling from the sky like a snowglobe.. Looks like a cloud but its snow.


Cold air is very dense and this makes its capacity to hold water vapor molecules very low. When you throw the boiling water up, suddenly the air has more water vapor than it has room for so it clings to particles forming crystals.


Just has to be below 0F to do this and the water has to be boiling. What -50C???
Also better to have low humidity too.




Check this out from Mt Washington. Little extreme but same concept..

December 29, 2017. It's happening. 4th day staying below freezing and everything icing up.


Air Temp: 12°F (-11C)
5000' Temp: 0°F (-18C)


This entire river has moving water too. See video below.






I wouldn't walk on it yet though.





Hello.





Cool Formations

That's the situation after 12 hours of snowfall followed by a couple of hours of heavy rain, caused by a sudden flux of warm air this morning:






^curiously, the snow decreases when moving up on the mountain. The picture is not particularly clear, but in the low part of the mountain in this picture the trees look greyish because they have snow on the branches, while the trees above them look brown and don't have any snow on them. This happened because the sudden temperature rise that turned snow into rain hit the high altitude part much harder than us: just for making an example, the weather station in the bottom of my valley today measured temperatures of 0/1°C, while a weather station at 1500 m of altitude on that mountain side today reached 6°C.

Some pictures I took downtown:








How the road looked like:
