Lock Screen weather widget missing icon for snow weather.

On the Weather wallpaper lockscreen, a few weather related widgets are placed by default. One shows the amount or likelihood of precipitation over the next hour. This has always worked fine with rain, but tonight I got snow for the first time and noticed the icon representing snow is missing, doing a generic white page icon.

I've included a picture of the widget so you know which one I mean.

I've tried removing the weather app from the phone and re-adding it. There was also a minor update to iOS 17, but I've applied it and the bug continues. The phone says there are no new versions to update to.
