From the webcam:
The Portal Road looks completely dry -- no snow for a thousand feet above it. So unless too much rockfall has made a mess, you will probably be able to park at the Portal.
The willows in the North Fork: Looks like some snow in the bottom of the canyon. But up by the Ebersbacher Ledges appears dry. I think you will find significant snow from Lower Boy Scout Lake and above.
Looking forward to any info you can report back. Have a good trip!!!
