I was at Horseshoe Meadows today, and that's about 1,400' higher than Whitney Portal. The road was in good shape - just a few icy spots where it's constantly in shade, and I think they were all above the 8,500' mark. Doesn't mean the Portal Road will be identical, but they're only a few miles apart.
On a tangent - about 1/2 down we stopped and talked with an Inyo County transportation fellow who had pulled his truck over on the shoulder. Turns out he was headed up but his plow was giving him problems, and he was curious about rocks in the road (they were nearly non-existent). I was impressed to see they're still monitoring the road this late in the season.
