The meltoff's pretty advanced compared to a normal year. I went a few miles up Lyons Creek trail two weekends ago, and it's rare that the Wright's Lake and Icehouse roads are open for Memorial day, much less the trails clearing off (admittedly, the trail itself was a creek and not a trail).
We have had a lot of warm, sunny weather since then and now it's downright hot. The high basins and chutes are certainly still snowed in, but I imagine they're melting off quickly. It "helps" that we had the driest Sierra spring since recordkeeping began.
