Right now I think I'll go 96 Fri/Sat/Sun for ORD, with a peak DP during the period of 78.
Tomorrow has the coolest start out of the 3 days, but will feature by far the warmest UA temps. Sat/Sun have warmer starts, but cooling UA temps each passing day, and Sun has compressional heating potential with the front approaching. The wild cards will be the MCS/OFB/cloud debris potential for Fri, and then potential cloud debris issues on Sun as well.
