Has there ever been a case where an aircraft has blown up in a thunderstorm?

Didn’t think so.

Has there ever been a case where an aircraft has blown up in a thunderstorm?

There is no evidence that it "blew up." Indeed, the evidence reported so far seems to indicate a progressive failure extending over several minutes.

From this analysis: Breakup of a plane at higher altitudes in a thunderstorm is not unprecedented; Northwest Flight 705 in 1963 and more recently Pulkovo Aviation Flight 612 in 2006 are clear examples.
