For supporting background info: On 4/24 at 0051z, there were many scattered thunderstorms in that area. They grew in magnitude and coverage as the evening progressed.

Here is a radar loop of the area during the time you were recording. I left the METAR overlays active so you can see if there’s a correlation with the disappearance of the sim data with any changes in your airport’s (KISW) METAR or that of any other nearby observations. Note that a couple frames are missing. Also keep in mind that the in-sim weather often seems to be delayed by 30 mins or so.

It looks like the sim is generating the general area and movement of the precipitation correctly - the best way to observe this is to scrub your video time bar to the right and observe the general precip pattern then compare it to the video I produced.

Of course, the sim is very sparse on details and correct behavior. Just generalities.

But scrubbing your video forward also reveals that there are intermittent periods where it all disappears, which is obviously not what happened irl.

You can also see hard edges and rectangular grid patterns in the sim radar, similar to what several of us reported happening in Northern California a week or so ago.

Personally, thank you for taking the time to document such a long stretch of this happening. This is good evidence of an issue.
