Moist cold air will likely drip on your equipment and dew is an issue even with dew heaters. Also high humidity in the air will create a haze fog like which will affect transparency and you might even pick up light pollution more easily depending on your location. All in one it can be a nuisance. Nothing beats a cold crisp winter night IMHO. Every time I went to Wiruna and the weather was wet it was a waste of time. The skies were dark and clear but the transparency was an issue and the end results not worth it. Bloated stars, noise etc...
