Narrative:

A310 was climbing out of cle sbound and stopped at 17000 ft. LJ35 was sbound descending to FL190. I needed to have LJ35 level at the boundary at 10000 ft; so I put on the 5 mi line and climbed A310 and descended LJ35. A310 increased speed so I turned both aircraft (A310 to the right; LJ35 to the left). What compounded the situation; was WX in ZOB's and ZID's airspace and flow rerte that made it impossible for another area to descend lck and cmh arrs early. The area was understaffed; and the area; along with area 4; should have had sectors open or a radar associate to help during thunderstorm.

Title: ZOB CTLR EXPERIENCED OPERROR WHILE CLBING AND DSNDING CONFLICTING ACFT.

Narrative: A310 WAS CLBING OUT OF CLE SBOUND AND STOPPED AT 17000 FT. LJ35 WAS SBOUND DSNDING TO FL190. I NEEDED TO HAVE LJ35 LEVEL AT THE BOUNDARY AT 10000 FT; SO I PUT ON THE 5 MI LINE AND CLBED A310 AND DSNDED LJ35. A310 INCREASED SPD SO I TURNED BOTH ACFT (A310 TO THE R; LJ35 TO THE L). WHAT COMPOUNDED THE SITUATION; WAS WX IN ZOB'S AND ZID'S AIRSPACE AND FLOW RERTE THAT MADE IT IMPOSSIBLE FOR ANOTHER AREA TO DSND LCK AND CMH ARRS EARLY. THE AREA WAS UNDERSTAFFED; AND THE AREA; ALONG WITH AREA 4; SHOULD HAVE HAD SECTORS OPEN OR A RADAR ASSOCIATE TO HELP DURING TSTM.
