Bubbles in ceiling

[KenSanLan]

We just walked into our '85 Excella and found something I swear wasn't there two hours ago. There are bubbles in the bedroom ceiling near the fan and light. I am attaching photos. Does anyone know what this could be? It isn't raining, the fantastic fan has been running while we were out to dinner, no exterior damage EXCEPT a recent hailstorm that cracked a/c shroud - hubby taped the cracks. Ideas??

It looks like water separating the vinyl sheet covering the plywood (or hardboard or whatever it is) ceiling liner. Poke one of the bubbles with a needle and see if water comes out. If so, that A/C shroud may be leaking.

Poked holes with pin. Water in bubbles. Some will squish out, some of them are hard. Will check both fan and a/c. Thanks.
