Perhaps academic for this year, unless you are up for the lengthened approach. But it can be "corn-like" without a real big melt-freeze granules and consolidated to-depth. It all depends on timing and luck. I hit St Helens in March a few years back after a small bit of fresh snow hit the upper mountain and then there had been a few sunny warm days, on the morning after one clear night. I started early, moved relatively fast (for me - I was setting no speed records though...), and started down a ways before noon. It was firm for the first little bit from the top, but the skiff of fresh snow made that pretty OK, and then I hit a long stretch on which the surface had melted down a bit, but not enough to punch through the crust. Down toward where things flattened out a bit the warming had made it through the crust so it was classic "riding the canoe" style skiing down to the flats. It was a very fun day out with much of the turns on snow that felt very much like smooth spring corn. But I'm sure if I was a bit later on my descent it would have been somewhat less fun.
