Clutch Plates finally going?

[Randy B]

That sounds like a hydraulic issue, not the clutch itself. If the clutch was bad you would have slipping and late engagement, not early engagement.

I'd inspect your fluid level first and go from there.

Thanks Randy. That sounds hopeful. Would that also explain the apparent temperature sensitivity of the matter? Clutch operation was normal once the bike warmed up

Yes it would, especially if the fluid has never been changed. Brake fluid is hydroscopic (it wicks in water) and that will cause a mushy feel to both your brakes and your clutch.
My suggestion is change the fluid in both brakes and the clutch and then bleed accordingly. If the issue persists you may have a failing clutch slave or master.
