It was already a cooler than average summer across Arkansas heading into August, and a cloudy and wet pattern during the first week of the month kept the heat away. In fact, below average temperatures were noted across much of the country east of the Rockies. This was due to a cold front riding a northwest wind flow aloft all the way to the Gulf Coast.

A storm system aloft interacting with the front produced several rounds of heavy rain across southern and western sections of the state on the 6th and 7th. Much of the south and west received one to three inches of rain, with locally more than four inches.

Arkansas got a preview of what was to come on the night of the 5th. In Kansas City, MO, two to more than five inches of rain shut down a portion of Interstate 35 (flooding), and numerous water rescues were performed (stranded motorists). During the predawn hours of the 6th, a quick one to two inches of liquid dumped from Highfill (Benton County) to Fort Smith (Sebastian County).

 

Reports of heavy rain and flooding were noted from eastern Kansas into western Missouri late on 08/05/2017. Early the next morning, wind damage and isolated tornadoes occurred in northeast Oklahoma.

Before rain moved into Arkansas, there was severe weather in Oklahoma. Between 100 am and 130 am CDT on the 6th, a couple of rare August tornadoes hit Tulsa, OK. One of these was rated EF2, and cut a seven mile swath through the city. Multiple businesses were heavily damaged, and at least twenty five people were injured. A third tornado was counted northeast of town near Oologah, OK. The state averages only one tornado during the month each year.
