These two sites should give you some good info. The second link is to the weather station at the lower saddle, gives a good indication of possible temps.

I walked through up to 8" of snow and on 4' drifts hiking Peak 11,040'+ in the SW Absaroka on Sunday, 3 days after the last snow. I would guess the Tetons got in excess of 1' of snow out of those storms too. They looked pretty wintery on Friday.
