    This Christmas Day is on par for this December, with continued mild weather.  Forecast highs in the lower to mid 40s are well above normal and have been common this December.  Stats for this Christmas include:

• The Christmas Eve nighttime temperature did not drop below freezing at the official Chicago observing site (ORD).  This was the first Christmas Eve night to not have freezing temperatures since 2005.
• The minimum temperature for the Christmas calendar day in Chicago is likely to be in the top ten warmest since 1885.  If the temperature does not drop below freezing before midnight, it would be only the sixth occurrence on record for a Christmas in Chicago (a return frequency of once every 21 years).
• The high temperature forecast for today is right at the cusp of a top ten warmest high temperature on Christmas Day for both Chicago and Rockford.
