Given dangerous heat, Excessive Heat Warnings were issued for parts of Arkansas for several days by the National Weather Service. Such a headline is posted when heat indices meet or exceed 110 degrees.
Heat continued to be the main headline through the 21st. There were scattered afternoon thunderstorms, mainly in the northern half of the state. A few of the storms were severe.
From the 18th through the 21st, severe storms delivered a 67 mph gust at Pocahontas (Randolph County), destroyed a metal barn southeast of Attica (Randolph County), and pelted Sellers Store (Sharp County) with quarter size hail. Trees were downed north of Hardy (Sharp County) and at Capps (Boone County), with power lines downed at Lakeway (Marion County) and Mountain Home (Baxter County). A quick two to three inches of rain flooded roads near Pocahontas (Randolph County) and Viola (Fulton County), and a gravel road was washed out at Bergman (Boone County).
