Narrative:
Climb out from C77 was controled by rfd departure who had good radar coverage of the thunderstorm activity. After leveling at 8000 ft and changing to ZAU there was no coverage of the WX and we got into a pretty heavy circuit breaker. At one point we went to 8500 ft and the controller called me on it. I reported that we were in heavy rain and turbulence and gradually worked back down to 8000 ft.

Narrative: CLBOUT FROM C77 WAS CTLED BY RFD DEP WHO HAD GOOD RADAR COVERAGE OF THE TSTM ACTIVITY. AFTER LEVELING AT 8000 FT AND CHANGING TO ZAU THERE WAS NO COVERAGE OF THE WX AND WE GOT INTO A PRETTY HVY CB. AT ONE POINT WE WENT TO 8500 FT AND THE CTLR CALLED ME ON IT. I RPTED THAT WE WERE IN HVY RAIN AND TURB AND GRADUALLY WORKED BACK DOWN TO 8000 FT.
