Summary:
Right now windy conditions are not handled at all. I live in an area with very frequent
windy conditions especially during certain times of year so this is annoying because I
see the purple question mark icon a lot, which in the past has made me stop using the
weather widget.

This patch implements handling for windy + clear and cloudy conditions for NOAA. I
don't know how to implement this for Wettercom.

Depends on D24537

Test Plan:
Before: {F7568603}
