Ummm yeah, we got 16 on the mountain, but its supposed to be 60 degrees this weekend/into next week. Sadly, it will melt.
That being said, you could do mammoth, but if you really are looking for a turn around trip. I'd go to bear/summit before Brian Head. Big Bear/Summit is about the same size as far as developed acreage goes but Big Bear has way more permitted terrain that is easily accessed and therefor bigger. So unless it's a blower powder day and Utah is about to get 20 inches while you are there, go to Big Bear.
