The archived warnings, watches and discussions in force at that minute are drawn over the scan, this one among them.
Did it verify
Not verified. The Iowa Environmental Mesonet's Cow found no qualifying storm report inside this flash flood 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.
The nearest sounding before it
Little Rock, AR (KBYH), launched 00:00Z, 2.7 hours before the alert went out and 33 km from the middle of its area. This is the routine balloon launch nearest before it, the air the forecaster had in hand, not a measurement taken for the alert.

What forecasters said that day
The local office's own words before this flash flood warning went out, as it sent them, from the Iowa Environmental Mesonet's archive of National Weather Service text.
NWS Memphis, TN wrote its last area forecast discussion before this flash flood warning went out at Jul 9, 9:03 PM CDT, 40 minutes earlier.
Area forecast discussion, Jul 9, 9:03 PM CDT, 40 minutes before
Area Forecast Discussion National Weather Service Memphis TN 903 PM CDT SAT JUL 9 2016 .DISCUSSION...Surface analysis this evening indicates a quasi- stationary boundary located from West Central Missouri into Southeast Missouri and along the Ohio River. Water Vapor Satellite trends over the past hour or two have indicated warming cloud tops over southern Missouri, North Mississippi, and Northeast Texas. KNQA/KGWX WSR-88D radar trends have indicated weakening intensity of shower/thunderstorm activity. As of 8 pm CDT, temperatures across the Mid-South are predominantly in the upper 70s to lower 80s. Latest 00Z WRF/HRRR suggest the activity will gradually diminish into the overnight hours. Will make adjustments to the remainder of tonight's forecast to account for short term trends. Otherwise, forecast is in good shape. Updated grids will be available shortly. CJC && .PREV DISCUSSION... /issued 619 PM CDT SAT JUL 9 2016/ DISCUSSION... Updated to include the 00z aviation discussion below. PREV DISCUSSION... /issued 253 PM CDT SAT JUL 9 2016/ DISCUSSION... Numerous showers and thunderstorms have developed along an old outflow boundary across North Central Mississippi this afternoon. This the area will be the main focus of development into the evening hours. Activity should dissipate by the overnight hours. A weak upper low will remain in the vicinity of the Mid-South through Tuesday. In addition, a weak stationary front stretches along the MO/AR and TN/KY border. As a result, chances for scattered showers and thunderstorms will continue. Some locations may receive locally heavy rainfall while others see no rain at all. Too hard to pinpoint where initiation will occur. A lot will be determined by where lingering outflow boundaries exist or where the frontal boundary sits. Highs will remain in the mid 80s to lower 90s. After Tuesday, rain chances will diminish and will be more diurnal based. Highs will return to the lower to mid 90s. A cold front will begin to approach the Mid-South on Thursday and will bring increased rain chances for northern portions of the Mid-South for the end of the week into early next weekend. KRM AVIATION... Expected isolated to scattered SHRAS and TSRAS this afternoon into the early evening with best coverage across North Mississippi. Outside of TSRAS expect mainly VFR conditions and light winds through the period. Beyond this afternoon/early evening it is difficult to pin down another round of activity so will leave mention of SHRAS/TSRAS out after this evening. Some light fog is possible late tonight. SJM && .AVIATION... 00Z TAF cycle Scattered convection over north MS continues to diminish this evening, but we've seen an isolated cell develop just north of KMEM. This cell may briefly pulse up, but shouldn't persist long given the weak vertical shear. Most of the area will remain stable overnight, limiting the potential for convection. However, areas that clear out may see patchy fog development. MVFR visibilities were included at the TAF sites outside of Memphis. Scattered showers and thunderstorms are expected again on Sunday, but confidence is low that thunder will affect the forecast terminals. Thus, only VCSH was included during the late morning and afternoon hours. Johnson && .MEG Watches/Warnings/Advisories... AR...None. MO...None. MS...None. TN...None. &&
