Is a link to one station's data:  Cottonwood Lakes out of Lone Pine CA.

It is in the most southern high Sierra area (and highest trail head at around 10,400').  This source is at the lakes about another 600' up and 6 miles in.

Looks like Father's Day will be a good plan.

Other similar data sources (e.g., lower Tyndall Creek still has 67") available ...maybe at your favorite spot.

A very warm May/June will make for spectacular waterfalls, adventurous water crossings, mosquitoes and clear trails. In places, 200+% snow pack over last year but it is falling fast.  Except for the highest passes it is expected the snow will be around where you went last year about two weeks longer than usual.  Some passes over 11,000' will still have snow coverings/remains into September.  Going to be some flowers coming out this year.

My permit came Saturday and our group is counting for an early thaw. Our plan is to hike from Duck Pass to Thomas Eddison Lake on the JMT then after a day or two at Vermillion take the ferry back to he trail. From there we will hike up to Mono Pass and exit at Mosquito Flats. I hope that the snow thaws enough to follow the JMT otherwise we will drop down to the Cascade Valley trail or even lower if we have to. I would much rather take the JMT and spend most of our trek above 10,00ft though.

I'm guessing that anything before near end of June above 11,000' will still be snow covered.  Winter weather is almost as local as the summer showers are.  The Mammoth area probably gets more than its share of rotten winter weather - hence the ski area.  Many years ago, we left Mammoth in a rain and snow storm, drove around the ridge to a partly cloudy sky at Duck Pass and returned to Mammoth's non stop nasty day.

Go here to stumble around looking for your area.  For example put in 'mammoth' or 'mono'.

End of March there was 128" on 11,450' Mono Pass and recent 12" on Vermillion.

Bring back some pictures.  That is some very nice scenery - if you can stay on the PCT/JMT.

Courtesy of another forum.  Hikerchick is from Bishop on the eastern side of the Sierra.  She usually does weekly walk ins from open trail heads along US 395. 

Still a lot of water locked up there.  The first picture is looking into the Bishop pass area.  Usually this time of year it is a nice late spring day hike up to see the spectacular run-off from the 13,000 ridges.  Maybe in a few weeks.

Sure looks like an aweful lot of snow for June, come on sunshine! I saw on the VVR facebook page that they got 9" of snow on Kaiser Pass last night. Thanks for the link.
