Central Indiana 2013 Summary

2013: A Year in Review
2013 provided quite the change from the warmth experienced in 2012. Winter took its time coming to an end, with two big snow storms occurring in what would be one of the coldest Marchs in recent history. The 4th snowiest March in Indianapolis history had Hoosiers pining for spring warmth and ensured an above normal year for snowfall. The combination of the snow melt at the end of March and the 2nd wettest April on record brought widespread flooding across central Indiana during the second half of the month.
 
As spring transitioned to summer, it became clear that the exceptionally hot weather experienced during portions of the 2012 summer would not be making a reappearance in 2013. High temperatures reached 90 or better on just 14 days, well below the 51 days of 90+ degrees in 2012.
 
The most active period of the year was arguably over the last two months, as central Indiana was impacted by everything from significant severe weather and tornadoes, to snowfall and record flooding. The biggest event of 2013 to affect the region was the tornado outbreak on November 17. 28 tornadoes touched down in Indiana that afternoon, 15 alone in central Indiana, making November 17 one of the most active days for tornadoes in state history.
 
After a period of active winter weather from late November through mid December, an intense storm system brought record rainfall and widespread flooding to the region just a few days before Christmas. Indianapolis experienced their 2nd wettest December day on record on December 21, when 2.57 inches of rain fell.
