wind chill factor calculation not valid for temps over 50F

The "wind chill factor" calculation is reporting unrealistic values for warmer temperatures. A recent run shows an actual temperature of 86F and a wind chill factor of 91F. While the calculation is technically correct based on the formula it is not a realistic value since wind chill is only defined for when the observed temperature is at or below 50F. Is it possible to implement a check that removes wind chill if the temperature is >= 50F?

See: "Wind Chill Temperature is only defined for temperatures at or below 50°F and wind speeds above 3 mph." (https://www.weather.gov/safety/cold-wind-chill-chart )

There is already a check:
If the wind speed is less than 5km/h the normal temperatur without any wind chill factor will be used.
I will add a ticket for only enabling the wind chill factor calculation for temperatures at or below 50°F.
(But the ticket will have a very low priority)

Thank you. I should have flagged this issue as low priority.
