What temp to start looking for WI formation?

[Chad_A]

I know it's not right at 32 degrees (0C). With all the water running on the faces right now, how cold will it have to get to start to freeze it up? Mid 20s? I'm sure that wind has something to do with it. I google searched it, but didn't come up with anything.

In bozeman we look at the night temps the most. About four days of a good cold snap does the trick if you don't mind stubbies. Also keep in mind that then ground temp is a big part until the ground begins to freeze the ice on the top won't (generally). But it could be different in the cascades with more humidity

[Chad_A]

Oooh, ground temps. Good point; hadn't thought of that one.

try and cool a glass of room temperature water below room temperature by only blowing on it..

So if its getting down to 4 degree F at night, should ice start forming up?

Point taken, but temperature wasn't the only thing I was thinking of; I'd imagine if a stiff wind was blowing, it might turn the water into more of a mist than a running stream of water, making it more apt to freeze.

I am not exactly sure what you are asking.

[Chad_A]

Ok, I'll restate more clearly. What temp to start looking for on telemetry sites to start to suspect water ice formation.

I've simply been looking for 4 or more consecutive nights below the freezing point. For the last three years that's worked pretty well.

Hey, vw4ever

 

You can check my site and under weather I have stored and graphed all the data from the NWAC site for each station. You can go back a few days and look at the graph to see if a good freeze thaw has been happening.

P.S.:The weather links are broken, but I haven't had time to fix them.

Thanks, Scott, let me know when you get the links fixed!

 

Cheers,

helping, because if you pick up on the sublties in that post they will tell you that ice formation is a complex matter involving not only temperature but aspect, elevation, water flow rate, etc.
