The normal average temperature for the season, which goes from the autumnal equinox to the winter solstice on Dec. 21 and is an average of all temperatures recorded (overnight lows to daytime highs and everything in between), is 37.6 degrees. When the climate prediction center determines a seasonal forecast, there is about a one-third probability of having what forecasters consider above normal, below normal or normal temperatures. Again this year, instead of the typical 33% probability of warmer temperatures, the center says there is a 40% chance of warmer temperatures.
