Does anyone else have this? I am on short final, then all of a sudden, a split-second stutter, and the weather (clouds and visibility) suddenly changes. The sky goes from clear to cloudy in an instant. No weather addons in use. 

I haven‘t had it as extreme as you describe. But I absolutely withess something like a flash and the sky colours (and haze) changing within 1 sec. But the cloud coverage seemed to stay more or less identical as it happened (every 30-60 minutes as an estimate)

Interesting discovery. After the latest update, my two friends and I noticed this problem. So far, five people from different PCs, internet providers, and locations have encountered it. 

I have seen it too. 

Ahhh I am glad it isnt just me then

Same here.

Sometimes and other times it’s completely wrong weather being depicted.  Like the other day it was clear and 91F here in PDX and XP12 showed heavy cloud cover … after about 20 minutes it thinned out a little but didn’t match real world weather at all (clear sky all day).

It’s definitely hit or miss on how the live weather is depicted … sometimes it’s very close and sometimes it way off.

I do use HiFi weather also, but not enable in this case.

Does it happen also with ActiveSky that uses METAR?

I noticed the same issue with AS, even though they get the WX from their data servers (as they claim). I did not notice this issue until ASOBO's latest update. It looks like the same, new update, new bugs.

I don't want to stir the pot, but I think you switched the forums or Laminar Research with Asobo. 🙂

I don’t understand. You asked whether this also happens with Active Sky, which uses METAR data. Let me answer again clearly: yes, it does.

This issue started after the latest ASOBO update. Before that update, it was not happening. I hope this finally clears up the misunderstanding.

What ASobo update? This is X-Plane forum. Asobo has nothing to do with X-Plane.
Also, Active Sky exist/supports both MSFS and X-Plane.

Yes, you are 100% correct. I have both (XP12 and MSFS) and have been having the same issue, reacting completely wrong based on MSFS. SORRY!

No worries, happens to the best of us. 
Speaking of ActiveSky, its trademark is a sudden change of weather, in both MSFS and XP. It's simply how it works. It loads new METAR data every X minutes (depends on what we choose in the options), and some weather stations  apparently change METAR data on every 30 or even 60 minutes, so for example during approach, weather can change from CAVOK to 6/8 cumulus, and it ruins the immersion. I've learned to ignore that, but it's not easy when you know that default weather depiction has (had) smooth transitions.
