Narrative:

Major thunderstorms. Most; if not all; aircraft were deviating due to WX. B767 checked on at FL230 requesting FL310. MD82 was level at FL280 going direct okk.OKK1.ord. I planned to climb B767 to FL270 since MD82 was traffic for B767. Instead; I climbed B767 to FL310. Separation was lost. One problem I was experiencing was difficulty hearing. I had talked to my d-side several mins before asking if he could hear ok. He said; 'yes; I was able to hear; but it was weak.' supplemental information from acn 643481: the climbing aircraft was a flash through procedure from another sector. FL270 was in the interim altitude section of the data block; the radar position issued the aircraft FL310. Aircraft #2 responded to an RA.
