ya that's not great corn weather, I typically like upper 20/low 30s for nighttime lows to mid 50s (daytime highs) with clear skies for corn, but if the snow has fully transitioned or the crust is thick (almost fully transitioned) then you may be able to get away with it. Its also NW facing which buys ya some time, if it was directly east, I think you'd be screwed unless in position to ski near sunrise.
I'd also take my advice with a grain of salt. Corn in the wasatch is an elusive fruit and I'm often surprised to score corn when I was expecting mush or ice (and vice versa, ice instead of corn).
I feel out of touch with the snowpack right now as I was in Montana the first week of May and only skied "inbounds" over the weekend. Alta on saturday for day 100 and DV on sunday for mother's day. Both skied good, but I could have been later as both days I dropped in a tad early. Turns were good, but could have been gooder ;)
