The formulas used to calculate the wind chill index are:
Old Wind Chill Index (Pre-November 2001) = 91.4 - (0.474677 - 0.020425 * V + 0.303107 * sqrt(V)) * (91.4 - T)
New Wind Chill Index = 35.74 + 0.6215T - 35.75(V0.16) + 0.4275T(V0.16)
where: V = wind speed (mph) T = temperature (F)
(V0.16) is V to the power 0.16
Definition of windchill. : a still-air temperature that would have the same cooling effect on exposed human skin as a given combination of temperature and wind speed. — called also chill factor, windchill factor, windchill index.
It looks like some even colder temperatures are coming. Paul
