May started out chilly and stormy, but also relatively cool. By the end of the month though, temperatures soared into the 80s. More storms fired and produced severe winds and hail on May 29.
June saw more active weather as a derecho moved across the Miami Valley on the 23rd bringing with it heavy rain, hail and high winds. Widespread wind damage was reported as wind gusts topped 80 mph on the south side of Dayton. An EF1 tornado touched down near the town of Edgetown in Warren County.
More active weather returned in July with strong storms ripping across the area on July 13 and 14. However despite the storms in June and July, a rainfall deficit of over 3 inches created problems as drought conditions began to impact farmers.
The lack of rain along with well above average temperatures continued into August before beneficial rain arrived by the middle of the month. With the rain though came more severe storms. A tornado outbreak developed across northern and central Indiana and just clipped the northern Miami Valley on Aug. 24. More storms fired on Aug. 26 and 27.
Relatively quiet weather returned in September with only nine days of the month reporting any measurable rainfall. Temperatures also continued well above average with the last 90 degree temperature of the year occurring on Sept. 23. The unseasonably warm and unusually quiet weather continued into October and November with only 10 days of precipitation in October and only five days of measurable precipitation in November.
The weather pattern began to change dramatically as we flipped the calendar to December. Temperatures fell below average after the first week with several arctic blasts sending temperatures near zero. The first significant snowfall of the season occurred on Dec. 13 when a heavy snow band dumped nearly a half foot of snow on the south side of the metro area. Even the polar vortex made a dreaded appearance in the middle of the month forcing wind chill advisories a week before winter even officially arrived.
