Hello, I've noticed a few requests for a legend for the app format but I have not been able to find one or a post answering what this icon is.

Undoubtedly this will be embarrassingly simple, but here we are with me not figuring it out and needing to know, lol.

I appreciate the app, though it's beyond my capacity and I'm still learning how to use it.

I can't tell if it attached before I post, so here's hoping.

The icon with the sun/moon and lines, top row, at the top of hourly column. I understand it maybe indicating night or daytime but I don't know what the lines mean.
And then the series of 3 cloud icons starting rows bottom left... Rain expected, thunder/lightning expected, total accumulation?
