What happened

The episode as NWS SHV wrote it up.

An upper level ridge of high pressure was anchored over the Central Plains during the afternoon of July 6th, with weak impulses aloft in the easterly flow interacting with strong diurnal heating to generate isolated to widely scattered showers and thunderstorms across Southwest Arkansas, North Louisiana, East Texas, and Southeast Oklahoma. Given the strong instability that had developed that afternoon, some of these storms became severe, which resulted in a measured 67 mph wind gust at the Monroe Regional Airport, which downed trees near and just north of the airport in Ouachita Parish. These storms diminished during the evening with the loss of heating.

What forecasters said that day

The local office's own words before the first event, as it sent them, from the Iowa Environmental Mesonet's archive of National Weather Service text.

This Hazardous Weather Outlook is for portions of south central
Arkansas, southwest Arkansas, north central Louisiana, northwest
Louisiana, southeast Oklahoma, east Texas and northeast Texas.

.DAY ONE...This Afternoon and Tonight...

An Easterly flow aloft will persist across the Four State Region
with embedded disturbances expected to combine with available
moisture and daytime heating resulting in destabilization,
The result will be scattered showers and thunderstorms during the
afternoon and evening. A few of the thunderstorms will become
strong with gusty winds to 25-35 MPH, locally heavy rainfall with
amounts to near one quarter to one half inch, and deadly
lightning. Any hail that falls will be small. An isolated
severe storm could form with winds to near 60 MPH but that threat
is very small.

In addition, afternoon temperatures will climb into the middle
and upper 90s and when combined with the relative humidity can
produce heat indices from 100-108 degrees. If working or
venturing outside While outside, remember to take frequent breaks
in the shade, wear light weight clothing and drink plenty of
water.

.DAYS TWO THROUGH SEVEN...Saturday through Thursday...

Rain chances to continue through next week, as a series of
tropical waves progressing across the Gulf Coast States and
embedded disturbances within the Easterly flow aloft will
aid in the development of scattered showers and thunderstorms. A
weak cold front moving in Saturday will serve as an additional
focus for precipitation. Isolated strong to severe storms will be
possible, with damaging winds and brief heavy rainfall the main
threats.

.SPOTTER INFORMATION STATEMENT...

Activation of emergency managers, amateur radio operators, and
storm spotters, is not expected through tonight.
