Wonderful tool — for astronomers and for everyone!

This is the first weather-related item I look at in the morning. Even if I only pay attention to the top line of data, it’s a wonderful overview.

I also use it for my evening naked-eye observing — and for ISS viewing. For that I pay attention to all the other data rows.

I also like the various available map layers, especially the Smoke overlay.

Get this app and relish it!
