I hiked Whitney yesterday, and conditions are the Portal are similar to rest of the high desert - temps are well above normal, but expected to diminish beginning today.
In terms of trail conditions - the cable section shown in Bob Rockwell's photos have melted out a bit more. Just use a bit of care there, and in a few of the switchback corners, and no worries. The snowfield near the summit has a well-beaten path thru it. No need for any type of traction aids or ice axes, although several people were carrying them. And I'd echo Bob's comment re: skeeters - lots of them down low, especially in the morning.
Lots of folks on the trail yesterday - almost a carnival-like atmosphere. It was probably the warmest I've ever hiked Whitney, but even so, it wasn't unreasonably warm.
