We are expecting two storms this week that should bring rain to Yosemite, and snow down to about 6,000 or lower.
Not sure how that would affect a trip to Rancheria Falls, for example, unless the bridge over Wapama Falls is closed...Lake Vernon, on the other hand, will probably get some snow during the storms. That would probably cover the trail--not enough to make walking really hard, but certainly enough to obscure the trail. If you're not accustomed to following a route without a visible trail, it might make more sense to stick to Rancheria Falls....or maybe hike in from Lake Eleanor through Miguel Meadows.
On any spring trip, the key is to watch the weather carefully, be extremely cautious about stream crossings, and be prepared to turned around or change itineraries if things go wonky.
