A wet pattern set up in mid-July as a cold front arrived from the north, and moved very slowly through Arkansas toward the Gulf Coast (a process that took several days). The front triggered scattered to numerous showers and thunderstorms, and this resulted in several inches of rain in parts of the state.

 

In the video: The WSR-88D (Doppler Weather Radar) showed a lot of rain persisting for several hours in southeast Arkansas during the morning of 07/17/2021.
 

Between 700 am and 100 pm CDT on the 16th, Fort Smith (Sebastian County) picked up 2.69 inches of rain, and Highfill (Benton County) received 1.73 inches. A couple of miles north of Bonanza (Sebastian County), flooding was reported along Highway 45.

Late on the 16th and into the 17th, downpours developed and remained over southeast sections of the state for several hours. By 900 am to 1000 am CDT on the 17th, the observer at Kelso (Desha County) reported 6.49 inches of precipitation, and Rohwer (Desha County) had 6.55 inches. Near the latter location, Highway 1 was inundated with water and became impassible.

 

An impressive 6.55 inches of rain dumped at Rohwer (Desha County) in the twenty four hour period ending at 945 am CDT on 07/17/2021. This was the highest one day July total at the site, and the fourth wettest day all-time.

It was the wettest July day at Rohwer (Desha County), and the fourth wettest day all-time locally. The site had recently experienced the top two wettest days on record in June (on the 8th and 9th) when 19.22 inches of rain caused extensive agricultural losses. It was no surprise this would go down as the wettest climatological summer (June through August) with more than a month left to go in the season (27.86 inches of liquid so far which crushed the previous record of 25.47 inches in 1989).

 

Temperatures across Arkansas were mild at 1200 pm CDT on 07/17/2021. Readings were in the 70s and 80s at most locations.

Overcast conditions and cloudbursts on the 17th kept temperatures down. It did not feel like summer at all, with temperatures in the 70s and 80s at 1200 pm CDT. Thermometers showed 73 degrees at Clinton (Van Buren County), Monticello (Drew County), and Stuttgart (Arkansas County), 75 degrees at Searcy (White County), 77 degrees at Pine Bluff (Jefferson County), and 78 degrees at Little Rock (Pulaski County).

In the twenty four hour period ending at 700 am CDT on the 18th, Fort Smith (Sebastian County) was hit with another 2.84 inches of rain (a forty eight hour total of 5.57 inches). Two to three inch amounts occurred at Alum Fork (Saline County), Cane Creek State Park (Lincoln County), and Malvern (Hot Spring County).

The numbers went up in the next twenty four hours. A whopping 5.64 inches of precipitation proved to be too much at Ozark (Franklin County). High water damaged at least twenty homes and washed out roads.

 

Seventy two hour rainfall through 700 am CDT on 07/19/2021. Amounts were highest in west central and southeast sections of the state.

Just south of Mount Ida (Montgomery County), 3.75 inches was tallied. Malvern (Hot Spring County), Mountain View (Stone County), Pine Ridge (Montgomery County), and Waldron (Scott County) had two to three inches.

The aforementioned front exited the region to the south on the 19th before stalling along the Gulf Coast. As the front departed, El Dorado (Union County) picked up roughly three inches of rain in the morning. North of the front, isolated storms managed to pop up in the afternoon, and at least two funnel clouds were witnessed in eastern Arkansas. No tornadoes were confirmed. 

 

Too Much Rain and Too Many Tornadoes

Prior to the event, at least two dozen tornadoes were spawned in Iowa on July 14th. This was the third most tornadoes in a day across the state since 1980 (not far behind the record of 35 tornadoes on August 31st, 2014). The strongest tornado (rated EF3) tore a ten mile path through Lake City, IA (about 75 miles northwest of Des Moines, IA).

Monsoon season was off to a fast start in Arizona. At Flagstaff, AZ, heavy downpours coupled with a burn scar from a fire in 2019 led to flash flooding on the 13th. Streets turned into rivers as water swiftly flowed through areas normally covered with vegetation (until the fire). There were more high water issues in Tucson, AZ the next day, with people rescued from stalled vehicles. A rafting trip turned deadly along a flashy (rapidly rising) Colorado River at Grand Canyon National Park. One person was killed and there were a few injuries.

On the 19th, a creek swelled due to a several inches of rain west of Lindale, TX. The soil eroded, and a pine tree fell across Interstate 20. Multiple vehicles crashed, and at least four injuries resulted.
