Narrative:

Sju-ord flight. We were cruising into jacksonville's airspace at about the time we needed to avoid thunderstorms and were unable to get through to ny commercial radio. We veered to avoid the thunderstorms, getting approximately 10-12 NM off course, possibly not entering at the correct fir location.
