Heat Index calculation wrong?

[MeteoTwischkamp]

Hi,

I noticed in the current conditions block, that the calculation of the heat index seems to be wrong- currently the temperature is 14.2°C with a humidity of 73%. The apparent temperature looks correct -there's a storm here going on at present, so it definately feels like its below 10°C. However the heat index does look right at least to my layman's eyes- it shows currently 26.8°C. See the attached screenshot.

I tried to find a calculator for the heat index and entered these values however this would be a heat index of 14°C.

I will fix it, the HI should only be calculated when T>26.7, otherwise it should show "--"

Thanks a lot Jachym.

Now Windchill shows "--", too. Is this ok?

[Jachym]

Yes, windchill has upper limit too (if I remember correctly 10C, if the T is above 10, windchill is not defined and it also depends on wind speed, it is only defnied above certain value, I cant remember exactly)

Thanks for respone. I will look at it this evening - it should get cold and windy outside.

Update:
Working!
