Estimate day and night temperature from 24 hour minimum and maximum temperatures

This very simple template of just 5 elements (2 input parameters and 3 variables) is a scheme for roughly estimating the average temperature during the day and during the night.

Variable   Tave
    Tave =         (tmin+tmax)/2.0
Variable   Tday
    Tday =         (tmax+Tave)/2.0
Variable   Tnight
    Tnight =         (Tave+tmin)/2.0
Variable   tmax
    tmax =         Variable parameter
    Minimum = -50, Maximum = 50
Variable   tmin
    tmin =         Variable parameter
    Minimum = -50, Maximum = 50
