Not an expert, but sounds like it might have gotten sunburned? Was it out in direct sun for the three days? Since I am assuming you had it in the house up until that point, you should have acclimated it very slowly to direct sun. Maybe put it under a tree (shade) for a few days, giving it more sun a few hours longer each day. Usually 7-10 days should have been okay. By then it should have been fine to leave it in full sun...

Unfortunately, there is nothing you can do about the sunburned leaves( IF THAT'S THE PROBLEM). You can remove them or trim the plant. Do a search on the cactus and succulent forum for "whacking jades" or "trimming jades", there's a lot of info there. They can take severe pruning, I know I did it to mine...When it leafed out it was better than it used to look... Good Luck!!

I think it got too cold, if not wet - highly unlikely it got sunburned, though if it was very sunny and the tree wasn't acclimatized over 10 days to full sun, it's possible that it did overreact.

I've been bringing my jades outside for a few months now, and so I'd assumed that
they were used to the sun. However, the sun's energy really seems to take off
this time of year, and some of my plants turned bright, bright red - although
they'd been in full sun for months. As a result, I put my jades below the deck-rail
to provide a bit of shade from the intense morning sun (full eastern exposure).

Turning bright red is perfectly OK with Jades. It's just the plants reaction to strong sun and some folks like this on their Jades.

I like the red tips, too, John. I get my jades as red as possible, since the color diminishes over winter. Some folks take an indoor-climatized jade and accidentally/unknowingly plop it on a deck in full sun --- sun is good for jades, but the first exposures ought to be controlled. Maybe I'm finnicky.

Regardless, it does sound like the cold (or warm/cold/warm/cold cycle) might be what got to Trish's jade. There is a good chance it will refoliate, since the temperature didn't drop very low. I have a jade that was exposed to 30°F mid-April and it is now re-budding.

Good luck.
