My friend and I were able to drive to the Swift Creek trailhead at the end of April and only had to cross a couple of easily managable snow banks. We didn't walk down the trail long, but I imagine we could have made it a couple of miles before we encountered any real snow.
It's been really warm the last few days here too, low 80's around Trinity Center. So I would think by late May there are going to be a few places that will be fairly easy to get to.
And I think you are right, not sure if and/or when the Forest Service will be providing trail reports.
