Did it verify

Not verified. The Iowa Environmental Mesonet's Cow found no qualifying storm report inside this severe thunderstorm warning while it was in force. That is not proof nothing happened: reports are thin where few people live.

Cow counts a report within 15 km of the polygon while the warning was in force: a tornado for a tornado warning; hail of 1 inch or more, a gust of 58 mph or more or wind damage for a severe thunderstorm warning; a flash flood report for a flash flood warning.

What forecasters said that day

The local office's own words before this severe thunderstorm warning went out, as it sent them, from the Iowa Environmental Mesonet's archive of National Weather Service text.

NWS Little Rock, AR wrote its last area forecast discussion before this severe thunderstorm warning went out at Jul 21, 12:44 AM CDT, 25 minutes earlier.

Area forecast discussion, Jul 21, 12:44 AM CDT, 25 minutes before

Area Forecast Discussion...UPDATED
National Weather Service Little Rock AR
1244 AM CDT Sat Jul 21 2018

.UPDATE...

Updated to include the 06Z aviation discussion. Additionally,
the threat for severe thunderstorms remains across much of the
state through the remainder of tonight.

&&

.AVIATION...

TSRA continues across northwestern AR, and this activity should
overspread central/western terminals through 21/09Z. MVFR or worse
conditions, along with extreme turbulence, could be observed
in/near TS, but confidence at individual terminals too low to go
beyond VCTS mention for now. Will amend TAFs as necessary through
the morning. TS dissipates by 21/15Z with VFR expected through the
remainder of the period. Winds will be variable and gusty near TS,
then transition to westerly through the day Saturday. Speeds will
remain below 10 kts for the latter half of the period.

PREV DISCUSSION...(ISSUED 300 PM CDT Fri Jul 20 2018)

SHORT TERM...Tonight Through Sunday

At the surface, a frontal boundary remains stalled over far
northern Arkansas and southern Missouri. Outflow boundaries remain
over portions of the area from morning showers/storms. In the
upper levels, a ridge 5960 meter ridge remains centered over the
Panhandles region of Texas and Oklahoma.

Over the next few days, the ridge will contract or move westward.
This will allow the front to move down into Arkansas. Additional
showers and thunderstorms will be possible this afternoon into the
overnight hours along and ahead of the boundary.

With the ridge contracting, and surface flow becoming more
northerly, temperatures will be a little cooler. Heat index values
will be a little more tolerable, with values at/above 105 mainly
over the southwest half of the area. Issued a heat advisory for
tomorrow for most areas south of the Arkansas River (excluding
Little Rock).

Any overnight storms should diminish in the morning hours as the
front sinks into the state.

LONG TERM...Sunday Night Through Friday

The long term forecast will begin with an amplifying ridge of high
pressure over the southwestern US amidst a deepening trough
extending from the great lakes region into northern Florida.

The overall flow will remain uninterrupted due to a blocking Bermuda
High through Tuesday. At which point a cutoff low is expected to
form, and begin retrograding towards Louisiana through mid to late
week. This will change north/northwesterly flow into northeasterly
flow aloft, and will switch northerly surface winds around to the
south. This change in wind direction in the low levels will allow
for moisture advection and increased rain chances, especially across
southern and eastern portions of the state late next week.

Meanwhile, the ridge of high pressure will move westward towards the
desert southwest, which will allow several cold fronts associated
with the unsettled weather pattern to move through mid to late week.
Therefore, temperatures will be slightly cooler next week and near
seasonal averages.

FIRE WEATHER...
No significant fire weather issues are expected in the next seven
days. Minimum humidity will largely remain above 40 percent.
Scattered showers and thunderstorms will be possible, mainly
during the afternoons and evenings.
