I got no dog in this fight but it’s still 3 days out and it wouldn’t take much to get into the goods. Maybe its not a high probability but certainly possible.
The groomers don’t do anything to get the heart rate up. That’s the issue. At least if there are moguls the exercise gets blood flowing to the extremities. You finish a groomer and you’re just as cold if not colder as when you started.
I could/would ski on a day with temps like tomorrow, but only if I could get into the trees, where it’s somewhat wind protected and I’m working up some heat internally. Bombing down groomers at 40 mph when the wc is -30f, is no bueno.
