The problem

Calling weather.get_forecasts on my NWS entities is currently throwing:

Failed to call service weather.get_forecasts. Unknown error

I attached the detailed logs which seem to reference the icon, and @MatthewFlamm already diagnosed it as such. Happening with both of the stations I had added.
