Narrative:
Aircraft deviated for thunderstorms. I did not coordinate and next controller was too busy to hear pilot check in deviating. Sector should have been split. Supplemental information from acn 618165: aircraft X inbound to cle descending from FL330 to FL290. Aircraft Y to msp at FL310 deviated to the north into the path of aircraft X. WX in the west end of sector caused all aircraft in sector to deviate. Aircraft Y deviated more than anticipated.

Title: ZOB CTLR EXPERIENCED OPERROR NEAR FL330 DURING WX DEV PROCS BTWN 2 E145'S.
Narrative: ACFT DEVIATED FOR TSTMS. I DID NOT COORDINATE AND NEXT CTLR WAS TOO BUSY TO HEAR PLT CHK IN DEVIATING. SECTOR SHOULD HAVE BEEN SPLIT. SUPPLEMENTAL INFO FROM ACN 618165: ACFT X INBOUND TO CLE DSNDING FROM FL330 TO FL290. ACFT Y TO MSP AT FL310 DEVIATED TO THE N INTO THE PATH OF ACFT X. WX IN THE W END OF SECTOR CAUSED ALL ACFT IN SECTOR TO DEVIATE. ACFT Y DEVIATED MORE THAN ANTICIPATED.
