Very Hot/Pockets of Heavy Rain on July 23-28, 2017
 
A ridge of high pressure ("HIGH") moved just enough to the west to allow a cold front to approach from the north on 07/23/2017. A northwest wind flow aloft around the high pushed the front toward Arkansas.

High pressure to the west made its presence known heading into late July. The high forced its way through the Plains and into Arkansas, and it got hot!

 

Heat index values at 300 pm CDT on 07/23/2017 ranged from the mid 90s to around 110 degrees.

It was 98 degrees at Hot Springs (Garland County) and Jonesboro (Craighead County), and 97 degrees at De Queen (Sevier County) and Russellville (Pope County).

There was some relief heading into the afternoon and evening. A cold front worked its way around the periphery of the ridge (from the northwest), and helped trigger hit and miss thunderstorms in parts northern and western Arkansas. As storms became more numerous, they headed slowly southward through the Ouachita Mountains. Between 430 pm and 500 pm CDT, an isolated storm produced damaging winds on the west side of Conway (Faulkner County), and blew a tree onto a home.

 

The WSR-88D (Doppler Weather Radar) showed a cluster of showers and thunderstorms building toward central Arkansas from the east during the evening of 07/23/2017.

More storms flared up in eastern sections of the state and tracked to the west. Precipitation (some heavy) was generally in a narrow swath along Interstate 40 between West Memphis (Crittenden County) and Little Rock (Pulaski County).

 

Twenty four hour rainfall through 700 am CDT on 07/24/2017.

Some locations picked up more than two inches of rain. Twenty four hour amounts through 700 am CDT on the 24th included 2.70 inches at Nashville (Howard County), 2.37 inches at Keo (Lonoke County), 1.82 inches at Des Arc (Prairie County), and 1.72 inches at Marianna (Lee County).

At the latter location, parts of Highway 79 were temporarily blocked by high water. It was a similar situation at Carlisle (Lonoke County), with flooding along Highway 13. 

 

After a relatively cool June and few 90 degree days at Little Rock (Pulaski County), there were twenty two such days through the first twenty seven days in July.

The aforementioned front was followed by slightly cooler air on the 24th, but oppressive conditions returned on the 25th/26th. It wasn't triple digit heat, but thermometers showed readings in the 90s with abnormally high humidity levels. In northeast Arkansas, heat indices topped 110 degrees at places such as Jonesboro (Craighead County). Excessive Heat Warnings were posted by the National Weather Service in Memphis, TN.

Thunderstorms were very spotty, but unloaded a lot of liquid where they formed. On the 25th at Jonesboro (Craighead County), a quick 1 to 2 inches of rain flooded a couple of roads on the east side of town.

 

Oppressive heat (temperatures in the 90s and 100s) was shunted to the southwest of Arkansas by a cold front on 07/28/2017.

Storms were a little more widespread by the 27th as a new cold front loomed to the north. Appreciable rain (more than a quarter inch) fell north of Little Rock (Pulaski County), and nearly a month's worth of water dumped at a few places. At Beedeville (Jackson County), 4.25 inches was measured, with 3.70 inches not far from Rogers (Benton County), and 3.08 inches at Augusta (Woodruff County).

There was one instance of severe weather shortly before 630 pm CDT. East of Perry (Perry County), trees were toppled and blocked Highway 113. After dark (110 am CDT on the 28th), lightning struck a home near Woodlawn (Lonoke County) and started a small fire. A woman suffered minor injuries.

The front arrived on the 28th, with clouds and showers/isolated storms continuing. The front promised an end to the heat, with below average temperatures and much less humidity to finish the month.
