Summer of Rain 2015

This summer has been wet… very wet. Rain has fallen on far more days than not, and cloud cover has hung thick and heavy in what are historically much sunnier months. To top it all off, temperatures have been somewhat below normal.

How wet has summer 2015 been up through today? Meteorological summer runs June 1st-August 31st, and today makes the midpoint of that period, so I thought it would be a good time to check in and answer that question.

Here are the top 10 wettest summers through yesterday.

1. 1958: 12.54″
2. 2008: 11.68″
3. 1990: 10.93″
4. 2015: 10.66″
5. 1949: 10.40″
6. 1973: 10.23″
7. 1917: 10.06″
8. 1928: 10.02″
9. 1937: 9.75″
10. 1969: 9.38″

So 2015 is running the 4th wettest. It looks to be dry the next few days before more thunderstorms and rain return, so 2015’s position may end up rising.

What are the wettest full summers of all time? A few of the above years went on to be in the top 10, but not all.

1. 1958: 22.02″
2. 1979: 20.92″
3. 1995: 19.85″
4. 2003: 19.39″
5. 1969: 19.09″
6. 1915: 18.92″
7. 1992: 18.44″
8. 1973: 17.81″
9. 1989: 17.45″
10. 1949: 16.54″

Summer 2015 needs about 6″ more to reach into the top 10 wettest summers, which at the current pace is more than possible.

Odd Columbus Events #2

Date: July 9, 1913
Event Type: Weather

A severe hailstorm hit parts of the South Side on that Wednesday afternoon. In an issue of The Democratic Banner out of Mt. Vernon, the headline on July 11th read Streets Covered with Ice Boulders: Destruction Wrought by Hail Storm at Columbus.”

The article went on:
This city was visited by probably the most disastrous hailstorm in its history. The damage to crops and buildings in this immediate vicinity is estimated conservatively at $125,000. (About $3.1 million today).
South Side florists alone report losses of approximately $50,000. In hundreds of houses practically every window was broken. The ground on the South Side was covered by a thick layer of “ice boulders” for an hour or two afterwards. As a midsummer phenomenon it probably was without a parallel in this state.

Accompanied by 45 mph winds, the hail that fell was reported to be about 3″ in diameter. The hail was large enough to hit and fracture the wrist of J.W. Sprouse, a teamster, and shattered glass from a greenhouse was driven through the arm of William Bernard, a florist.

Ohio’s most infamous July 4th weather event, occurred in 1969. Severe thunderstorms developed over southeastern Michigan and moved southeastward into the Ohio lakeshore communities around 7:30PM on July 4th. Every lakeshore community from Toledo to Cleveland was affected, as well as areas further inland. The storms continuously trained over the same areas from Lucas to Wayne counties for several hours, dropping torrential rains, tornadoes, high winds, hail and lightning. Rainfall in a 100-mile stretch from just southeast of Toledo into Wayne County totaled 6″-14″. These rains caused record local flooding. All told, the storms of July 4th-5th, 1969 caused $65 million in damage, damaged or destroyed 10,000 homes, 7,000 cars, 104 businesses, 300 mobile homes and more than 700 boats. 41 people were killed and 559 were injured, mostly from flooding. This was the 3rd most damaging flood in Ohio history, behind January 1959 and March 1913. Columbus was too far south to see any of the storms and received just 0.03″ of rain for the period.
