And an image showing the snow amount they are dealing with.
Plows are plowing in 8 feet of snow one mile west of White Wolf (near Siesta Lake). This is a great image showing the work involved. It was taken on May 3rd.

Some news
Glacier Point Road opened for the season to vehicles on May 10, 2019.
.....and is closed again almost immediately.
A huge winter storm is blowing through so they have closed Glacier point road until further notice for safety reasons. This will almost certainly halt the progress of the plow teams on Tioga pass and will more than likely set them back with up to 21 inches of new snow accumulation expected !!

Plowing effort continues.
The crews have reportedly worked through the Olmsted Point avalanche zone and are clearing in the Tenaya lake area. Mono county crews are working there way along the pass from the east and have plowed about 1 mile along Tioga after the entry station. I'd say that puts them about 14 miles apart but there is still a lot of work to be done. In case you are wondering why it takes so long, here is a list of common causes from the Yosemite website that creates slow progress.
As it's a deep snow pack this year all of the above issues are likely to be a factor.Additionally, these are common causes for slow progress on the Tioga Road:
Road repairs, ditching, and brushing operations must occur once snow has melted back enough. The roads may also remain very icy even after they're plowed.
Avalanche zones (26 potential areas). The Olmsted Point avalanche zone requires careful work, including application of charcoal over the snow to help with melting and blasting the snow slab to make it safer for personnel.
Heavy snow pack slows the whole operation.
Trees that have fallen across the road and been buried in the snow can cause substantial damage to equipment and result in a stop to all operations until they're cleared.
Rockfalls buried by the snow can cause substantial damage to the equipment and result in a stop to all operations.
Snow storms during the opening require a stop to Tioga Road operations in order to plow and sand park roads that are open.
Late guess
A happy Californian because it is still raining will try June 13 at 9 am. Will ping poll next.
Another late storm causing disruption.
Another hazardous weather warning from the weather centre causing disruption to travel.
From Yosemite webpage.

Sonora (CA-108) and Ebbetts (CA-4) Passes both opened today. When I have time, I'll have to see how much further behind Tioga usually opens. For some details on the efforts to open Ebbetts, see https://snowbrains.com/ebbetts-pass-...-summer-today/
