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 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.

The nearest sounding before it

Roanoke, VA (KRNK), launched 00:00Z, 4.1 hours before the alert went out and 213 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.

THUNDERSTORMS FORMED ALONG THE OHIO RIVER...ASSOCIATED WITH UPPER

NOW LIFTING N OF THE AREA AND HAS TAKEN THE HEAVY WEATHER WITH IT.
AFTER THE LAST OF THE SHOWERS GRADUALLY WANE OVERNIGHT...CLEAR SKY
IN SOME AREA WILL ALLOW AREAS OF DENSE FOG...THOSE AREAS BEING WHERE
IT RAINED EARLIER.  FINE TUNED THE POPS TO REFLECT LATEST TRENDS
INCLUDING THE EXODUS OF PRECIPITATION IN THE E.  TEMPERATURES
OVERNIGHT LOOK ON TRACK.

CONTINUED HIGHEST POPS IN THE MOUNTAINS MON AFTERNOON AS THINK THAT
WILL BE MOST ACTIVE AREA GIVEN EASTWARD SHIFT OF UPPER LEVEL SHORT
WAVE TROUGH AND SFC COLD FRONT.  THE INCREASINGLY HARD TO FIND FRONT
SHOULD BE NEAR W EDGE OF FORECAST AREA AROUND DAWN MON AND THEN MOVE
E THROUGH THE AREA DURING THE DAY AND EARLY EVENING MON.  THIS TRACK
SHOULD FAVOR THE E PORTIONS OF THE AREA FOR DIURNALLY ENHANCED PRE
FRONTAL CONVECTION.  HIGHS MON ARE CLOSE TO WELL CONVERGED NUMBERS.

&&

.SHORT TERM /MONDAY NIGHT THROUGH WEDNESDAY NIGHT/...
H500 TROUGH AXIS CROSSES MONDAY NIGHT.  EXPECT SHRA ACTIVITY TO WANE
AFTER SUNSET AS INSTABILITY IS LOST.  HIGH PRESSURE BUILDS IN AT THE

CONFINED CHANCE POPS TO THE SOUTH FOR NOW...ALTHOUGH ISOLATED

LEVELS.  LOW LEVEL FLOW TURNS TOWARD THE SOUTHWEST FOR FRIDAY AND
THE WEEKEND...HELPING TO INCREASE DEWPOINTS AND KEEP PRECIPITATION
CHANCES IN THE FORECAST.

USED HPC GRIDS AS A BASIS.  KEPT A MAINLY DIURNAL PATTERN TO THE
POPS ON THURSDAY...AHEAD OF MOISTURE/WARM FRONTAL BOUNDARY.  FROM
FRIDAY ON...WE ARE IN THE WARM SECTOR AND INDIVIDUAL WAVES BECOME
TOUGH TO TIME.  ENOUGH MOISTURE AND SUPPORT MAY BE AROUND TO SUPPORT
PRECIPITATION AT ALMOST ANY TIME...AND THUS HAVE LOW CHANCE POPS
FROM FRIDAY THROUGH THE WEEKEND.

TRENDED SOME HPC TEMPERATURES TOWARDS THE ENSEMBLE NUMBERS...BUT MEX
AND THE ENSEMBLE WERE GENERALLY IN GOOD AGREEMENT WITH HPC.
