Need some ideas on fixing a heat issue

I have an AC unit and it's working. The grow space for the tent is small and the tent is small.

The tent usually hovers around 22°C - 25°C (71°F -77°F)

This morning the tent temps were 28°C (82°F).

All the fans are working, the inline fan is working too.

Does anyone have an idea why my temps would have jumped up?
Outside is a massive downpour rainstorm but humidity in the tent is still at 40%.

I'm still within the safe temp zone but if this continues, I may not be for long.

You didn't by chance move the temperature sensor?

Nope, everything is untouched from yesterday. That's why it's extra confusing.

Checked out the fans? Dehumidifier working hard? Ballist getting hot?

Fans are solid, no dehumidifier to check and ballasts are external.

Room temp is 17-20C

Are you running heating in the house

Nope, just cooling. The only heat sources in the tent are the lights and the temps have returned to their normal temps now that the rain has stopped.

That must have been some hot ass rain. So strange

I know this is a few weeks old. But I notice a few degree climb in my Rooms when it’s cooler outside (rain storm) because my central air might not kick in as much as normal or even not at all for a day or two. I have a window shaker on a smart plug in the room my tents are in for this reason.
