Was that 2008? I spent a cold 4th of July weekend in Grayson Highlands in 2008.

Once was camped at Icewater Spring shelter on the 4th of July. Noticed the weather was unseasonably cold, and learned the next day that LeConte Lodge had recorded an overnight low of 38F.
With rain gear, sleeping bags, and emergency shelter (in case anything kept us from getting to the campsite) meant that I was prepared and not in danger of hypothermia. But it points out that hypothermia in the south can still be a concern in the middle of summer. Something many day hikers to the area don't consider.

On the subject, again things turned out fine but I had a relative vacationing in the Rockies. Their hotel was at a low elevation and they drove up into the mountains for the day. Reached a location with snow on the ground and they got out of their car wearing shorts to check it out. The car wasn't in park and started to roll away. Fortunately jumped in the car and stopped it in time, at which point they realize just how screwed they could have been if they hadn't been able to stop the car.
