Thanks to all for the replies. Good to know our weather won't hold me back much in this. As for humidity, if the wood stays outside the RH isn't usually that low. Right now it is -3C and RH is 84%. The low humidity really is more of an issue indoors when you bring that low moisture content outside air inside and heat it up. RH in my house is often down in the mid 40's in winter but outside not so much. As long as it is the RH that matters and not absolute moisture content of the air I will be OK. If not then I could have issues with it. Only one way to find out, I guess.

My shop is not heated and I’ve built bows in there this winter in 20F with no problems.

Have to love the primitive bow websites. If one has a question about anything in the process of building primitive archery equipment, just log in and ask the question and you will get the answer. Very helpful and thanks to all.

I remember reading an article, about 20years or so ago, possibly by Dan Perry(Perry Reflex), where he said that in cold weather a bow becomes harder to draw, as draw weight increases. His fancy yew bows were prone to breakage in tension from these conditions. His whitewood bows were less susceptible to breakage but they were usually a little wider and flatter on the belly.
I don't know how much truth there is as I have never lived in an area where the weather gets much colder than freezing temp.
If it is true, bows tillered under cold winter conditions might turn out underweight in other seasons.

Relative humidity is the key here as stated.  My bows that sit up in my rack in the house here will be quite dry as winter months go by and susceptible to potentially breakage if I take it out and start shooting it without acclimating it’s mc a little first.  Sadly I’ve learned this the hard way.  Cold and very dry are bad combos.   Some woods are more resilient than others but it’s a potential issue.  The bow I broke recently was a tillered bow with no bow sealer or coating on it either.  That could also contributed to mc loss perhaps too.
