Rare December Thunder
Posted:
                    After the ongoing snow storm this Friday, a more powerful storm system arrives for 
Christmas Sunday.  Warmer air is expected to flood the state ahead of the storm system 
and conditions may be favorable for thunderstorms!  How far is having thunder in 
December?  The featured chart presents the number of distinct calendar days each month 
that thunder was reported by the Des Moines Airport weather station.  The red bars are the 
total for 2016 and the blue bars are long term averages.  The 0.3 days presented on 
average for December would equate to having one event every 3 years.
