Heat index regression: simple estimate base offset · case 02

Mild-temperature heat index values are tens of degrees too high.

Case contract

Input dry-bulb temperature in degF and relative humidity in percent. Compute the simple Steadman estimate 0.5*(T+61+1.2*(T-68)+0.094*RH); if the mean of that estimate and T is below 80 return it, otherwise use the Rothfusz regression with the dry adjustment (RH<13, 80<=T<=112) or the humid adjustment (RH>85, 80<=T<=87). Round to 0.1 degF.

Why this case matters

Heat advisories are issued from this value; a wrong branch changes public warnings.
