June 2008 Climate Summary

June 2008 Central Indiana Climate Summary
Warm, Wet, and Very Stormy
 
The weather this past June across Central Indiana was seemingly stuck in one position for much of the first half of the month – stormy. Day after day of torrential downpours and severe weather left beleaguered residents of the Hoosier State wondering if it would ever end. Fortunately, it did, as the month actually closed out on a much less humid and cooler note with highs failing to reach 80 degrees in many spots on the last day of the month. The following is a summary of everything that was weather in June 2008 in Central Indiana.
 
Temperature
The temperature this June was actually rather unremarkable. While the first 15 days of the month saw above normal temperatures, they were often above normal by only just a few degrees. The only 90 degree day of the month came on June 8, which recorded a high of exactly 90 degrees. An average June experiences 3 days of 90 or better, and just last year there were 5.
 
The month finished with an average temperature of 73.2 degrees, which was above normal by 1.6 degrees. While the first 15 days of the month were above normal, the 17th through 24th helped to balance it out by checking in with below normal readings each day. The coolest temperature this month came on the 19th with a low of 54 degrees, making this the 5th consecutive June without a low in the 40s.
 
Precipitation
Rainfall came in absolute over-abundance during this June. With 0.01 inches falling on the final day of the month, the total came to exactly 8.00 inches. This compares to the June normal of 4.13 inches, making this year above normal by 3.87 inches. It was enough to make June 2008 the 7th wettest June on record, and the wettest since 1998 brought 10.26 inches of rain.
 
There were several heavy rainfall events in June, including at Indianapolis 2.48 inches on the 7th and 1.58 inches on the 4th.
 
As heavy as these rain totals were, they pale in comparison to some other readings from across Central Indiana this month. Rainfall totals on the June 7th event were reported as high as six to ten inches in one day in many locations. An unofficial total of 10.71 inches came from Edinburgh during this rain event. The highest official rainfall total during this storm came from 3 Miles East of Center Point in Clay County with 9.50 inches measured. The official state record for one day rainfall still stands with 10.50 inches in Princeton on August 6, 1905.
 
These unbelievable rainfall totals in the deluge of early June lead to unbelievable flooding in south central and southern Indiana. River levels in many locations exceeded the highest water marks of all time. Flood waters on the White, Wabash, and East Fork White, as well as countless streams, creeks, and smaller rivers, challenged or bested the storied marks from floods of 1913 and 1875. There is much more information available on the NWS Indianapolis June 2008 flood page, available here.

For the year to date, 29.05 inches of rain has already fallen at Indianapolis International Airport. This compares to a normal through the end of June of 20.43 inches. Last year, there had only been 19.58 inches of rain through this point of the year, and droughts, not floods, were on everyone’s minds.
 
Severe Weather
 
After a remarkably quiet spring season this year (and a mostly quiet season last year), severe weather came storming back with a vengeance in June. There was a seemingly endless barrage of almost daily severe weather. Some of the most notable events came on the 3rd, 4th, 6th, 7th, 9th, 15th, 21st, and 22nd.  Numerous severe weather reports indicated that winds during severe thunderstorms reached 80 mph or more this month, and hail of golf ball size was measured.
 
June 3rd saw 5 tornadoes in the area, with the strongest being an EF-3 tornado that tracked to the town of Moscow in Rush County and through portions of Shelby County. There was also an EF-2 near Edinburgh, which tracked through northeast Brown, northwest Bartholomew, and southern Johnson Counties.
 
Outlook for July 2008
 
The outlook from the Climate Prediction Center indicates an enhanced likelihood of below normal temperatures and above normal precipitation in Central Indiana during July 2008.
