I was up that way on 4/19 - 4/20. Only went as far as Merced Cascade, but had no snow at all. When you go there will have been a couple of more weeks of snow-melt so I doubt you will need them.
Also went to Glacier Point on that trip, that did have some snow along the way. However I never took my spikies out of my pack. Because by the time I reached the snow areas it was afternoon and the snow was melting and sloppy wet. YMMV
