This is a known problem for at least a year or two.  The fix would
be to have a global time value that gets set every time a valid
weather update comes in.  Perhaps even a separate one for each type
of weather data?

Then:  Only output weather data if the data has not aged-out, or
only output the portions of weather data that haven't aged-out.

This would require code tweaks.
