The approach of low pressure aloft triggered numerous thunderstorms from the 30th into the early morning hours of the 31st. Tornadoes, severe thunderstorms, and flash flooding occurred. The flooding killed six people, and the tornadoes killed one. The same weather system caused severe storms and flash flooding again on June 1st. For the 24-hour period ending at 7 AM on the 31st, a band of very heavy rain fell from Waldron and Mena to Conway and Little Rock and then on to Newport and Augusta. Within this band, rainfall amounts of 3 to 5 inches were common, and isolated totals exceeded 7 inches. Also on the evening of the 30th, 3.09 inches of rain fell in one hour at Little Rock, breaking the all-time record for the greatest amount of rain in one hour in the city. The previous record was 3.00 inches on May 26, 1955. President Barack Obama declared federal disasters in these counties: Cleburne, Independence, Montgomery, Polk, Scott, Searcy, Stone, Van Buren, and Woodruff.

An mesoscale convective system developed over Southern Missouri and Northern Arkansas and pushed across Northeast Arkansas into West Tennessee during the early morning hours of May 31, 2013. A few severe storms produced damaging winds and flash flooding. A couple of weak tornadoes also occurred.

A brief EF1 tornado uprooted or snapped numerous trees in a cemetery, and an adjacent building suffered roof damage.

An EF1 tornado began around Greenlee Park on the east side of Brinkley and moved mostly to the north. It took the roof off a house, slightly injuring a person inside. A few other buildings had minor roof damage. Trees were uprooted or snapped off. The tornado continued into St. Francis County 2.5 miles west-southwest of Wheatley.

A weak tornado crossed from Monroe County into St. Francis County. A few trees and power lines were knocked down. Two tractor trailers were blown off Interstate 40 before the tornado lifted.

Lead time is measured from the issue of the warning in force to the touchdown time in the database, both of which were recorded to the minute by different people.

The Storm Prediction Center had this point in a Slight Risk, with a 0.05 chance of a tornado within 25 miles. The outlook in force was issued at 01:00 UTC.

28 more were confirmed in the United States that day.

Ratings are the survey's, read off the damage rather than measured; the rating scale is above. Tornado counts rise through the record as reporting improved, so a year in the 1950s is not comparable with one today except for the strongest tornadoes, which were always noticed.
