The problem with wood geometry isn't as much temperature driven as it is a function of variations in relative humidity - wood is hygroscopic which means that the moisture contained within its cells will tend to track atmospheric conditions (yes, temperature variations do affect the hygroscopy of wood to some degree). That feature of wood is sometimes greatly reduced by way of high temperature drying which permanently modifies the chemical composition of the wood cells and, hence, its behavior - if it's a species that survives the drying process, it will be a very stable and rot proof wood. Also, that wood will be permanently 'shrunken' and will thus be denser and, just as Nietzsche quipped, stronger.
(I do wonder what implications that would have on the functioning of the hardwood selected for these frames.)
Whether or not it is actually going to be a problem for you depends on a number of factors. It shouldn't be too troublesome to resolve if you decide to play it safe. You should really put a 'c' after those temperatures. Some of us Americans may wonder who thinks 32F is balmy. ;-)
