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

Springfield, MO (KSGF), launched 12:00Z, 8.8 hours before the alert went out and 202 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.

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE SPRINGFIELD MO
ISSUED BY NATIONAL WEATHER SERVICE ST LOUIS MO
338 PM CDT Wed Jul 23 2014

.SHORT TERM...(This Evening through Thursday)
Issued at 330 PM CDT WED JUL 23 2014

The cold front is now located near the Missouri Arkansas border
this afternoon. The bulk of the convection and stronger activity
has now pushed south of the area. Some scattered convection is
developing behind the front across southern Missouri this
afternoon as a weak upper level disturbance pushes south through
the region. This activity will slowly spread south during the
rest of this afternoon and this activity will push out of the area
early this evening with no severe weather expected. Brief heavy
rainfall and frequent cloud to ground lightning strikes can be
expect with the storms within this activity.

A slightly cooler and drier air mass will spread into the region
behind the front tonight into Thursday as the upper level ridge is
pushed slightly to the west over the Plains. Highs on Thursday
will range from the lower 80s across the eastern Ozarks to the
upper 80s across extreme southeastern Kansas and far western
Missouri.

.LONG TERM...(Thursday Night through Wednesday)
Issued at 330 PM CDT WED JUL 23 2014

The upper level ridge will build back over the central U.S. on
Friday into this weekend. Highs will warm back into the 90s each
afternoon with heat index values warming to around 100 to near 105
degrees each afternoon as increasing low level moisture also
spreads into the region. Highs on Saturday will warm into the lower
to middle 90s.

An upper level trough will push across the northern Plains on
Sunday and will then dive south across the region early next week.
This will push a cold front through the area. Scattered
thunderstorms will be possible along the front Saturday afternoon
into Sunday afternoon as the front nears and pushes through the
region.

The upper level ridge will be pushed back over the west coast
as the upper level trough moves over the eastern U.S. with our area
under the trough. This will result in below normal temperatures
through much of next week as highs in the upper 70s to lower 80s
and lows in the upper 50s to middle 60s occur.

&&

.AVIATION...(For the 18Z TAFS through 18Z Thursday Afternoon)
Issued at 1233 PM CDT WED JUL 23 2014

A line of thunderstorms will clip southwestern Missouri early this
afternoon and is expected to impact the Joplin terminal. MVFR
conditions with perhaps some brief IFR can be expected. Gusty west
to northwest winds will also accompany this line. Meanwhile, MVFR
ceilings will also persist for a portion of this afternoon across
southern Missouri. Skies are then expected to clear by mid-
evening. We are then expecting light fog overnight into early
Thursday morning. Winds will remain light out of the north tonight
and Thursday morning.
