I wouldn't.
Windchill is totally irrelevant here, as the rig does not have a slightly moist skin at 85?F, like a person does. And since your rig has the polar package, unless it is projected to go below the mid-twenties for at least 8 to 12 hours (NOT like overnight low of 25, which might hit that for a couple hours), I wouldn't worry about it. If you do get worried, I'd just turn on the furnace overnight, set to the lowest temp the thermostat allows.
And hey, btw, keep that white stuff over your way, we dawanany over here.
