My limited first hand experience is that crap weather, like a typical thunderstorm with rain or average snow fall (2-3 inches), it works just like normal. The main thing I see is a significant drop in available bandwidth during peak usage times.

Yeah, in my experience, time of day is a bigger factor than bad weather. But even peak hours haven't been an issue for me.
Starlink is my secondary failover internet. My neighbor really wanted it so I went halfsies on it with him. Fiber in my area is cheaper and faster. My neighbors aren’t big internet users; but they stream their TV watching, have smart phones and use a laptop rarely. They never complain about issues.
My internet has failed over to starlink for hours during main working hours and I never even noticed. I do zoom/webex/teams calls all day and it works perfectly for me when I do use it.
Nice
