Meteorological summer (June through August) was not all that bad as far as heat. There were only a handful of days with afternoon temperatures of at least 100 degrees. Last year, triple digit readings were much more common.

Through the summer of 2012, the mercury hit the century mark three dozen (36) times at Fort Smith (Sebastian County), 28 times at Little Rock (Pulaski County) and 21 times at Harrison (Boone County). The mercury did the same thing a combined 7 times at these sites this year.

So, what led to the mild conditions in 2013? A ridge of high pressure, which is often associated with oppressive weather and a lack of rain (and drought) during the summer, has been anchored over the western United States. Across the west, vegetation dried out given a dwindling ground water supply, and big fires ignited. Thousands of acres were torched. East of the high, including Arkansas, a steady supply of storm systems and fronts brought ample rain and kept temperatures down.

 

The pattern featured a large ridge of high pressure ("H") over the middle of the country at 100 pm CDT on 08/28/2013. As August ended, the high built across the middle of the country during the Labor Day weekend. As the heat cranked up, it felt more uncomfortable outside.

From the 28th through the 31st, temperatures were well into the 90s to around 100 degrees locally. Factoring in the humidity, afternoon heat index values maxed out between 100 and 105 degrees in most areas.

It was at least 100 degrees at Texarkana (Miller County) each day. One of the warmest readings during this four day stretch was 103 degrees at Russellville (Pope County) on the 31st. On that day, more than 50 people had heat related medical issues at the Arkansas and Louisiana-Lafayette college football game at Fayetteville (Washington County). At least a dozen folks were taken to the hospital.
