August 2008 Summary

August 2008 Indianapolis Climate Summary
Mild and Very Dry…
 
The weather this past August across Central Indiana was a complete opposite of the rest of the summer this year. The month reversed a trend of wetter than normal conditions that began back in May. Temperatures this month ended up being very close to normal, with very few days registering highs that were much above or much below normal. The following is a summary of everything that was weather in August 2008 in Central Indiana.
 
Temperature
The temperature this August was almost exactly “normal”. In fact, just like in July, not one day this month experienced an average temperature that was more than 10 degrees above or below normal. The closest was August 23rd, which was 9 degrees above normal. The month kicked off with temperatures slightly above normal for a the first 5 days, then shifted to near or slightly below normal temperatures in what was a prolonged stretch of very pleasant weather that lasted through the 20th. After then, the temperatures climbed into the upper 80s and near 90 degrees through the end of the month. There was only one 90 degree day this month, when August 23rd recorded a high of 92 degrees, the hottest temperature of all summer. An average August experiences 5 days of 90 or better. This year was a far cry from the record setting August heat of last year that brought 22 days of 90 or hotter. This brings our summer tally of 90 degrees to just 3, compared to a normal of 15.
 
The month finished with an average temperature of 73.8 degrees, which was above normal by 0.3 degrees. The coolest temperature this month came on the 11th with a low of 57 degrees, and the hottest high temperature was 92 degrees on the 23rd.
 
No temperature records were set this month in the Indianapolis area.
 
Precipitation
After months of excessive and overly abundant rainfall, it was as if an unseen faucet was suddenly shut off. The only rainfall of note this month came on the 5th when heavy showers and storms brought 1.57 inches of rain to Indianapolis. However, this was by and large the only rain that fell the entire month. Only two other days the entire month measured any precipitation, and both combined were a mere 0.26 inches.
 
There were two long stretches of no measurable rainfall, the first being 8 days in length from the 6th through the 13th. And the second being even longer, lasting 14 days from the 15th through the 28th.
 
The monthly total of August 2008 was 1.83 inches (86% of this fell in one day, the 5th). This is below normal by 1.99 inches. It makes August 2008 the 28th driest on record, and it is the driest August recorded in 6 years, when August of 2002 had 1.42 inches of rain.
 
For the year to date, 37.46 inches of rain has already fallen at Indianapolis International Airport. This compares to a normal through the end of August of 28.67 inches. Last year, there had only been 24.91 inches of rain through this point of the year.
 
Severe Weather
 
As is typical for August, severe weather diminished even further during the month. August is typically a month that is governed by strong upper level high pressure that suppresses severe thunderstorms.
 
There was one severe event this month on the 5th. Winds to nearly 65 mph and tree damage occurred in northeastern parts of Central Indiana near Muncie.
 
Outlook for September 2008
 
The outlook from the Climate Prediction Center indicates equal likelihood of below, near, or above normal temperatures and precipitation in Central Indiana during September 2008.
