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.
