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.

.SYNOPSIS...
A WARM FRONT MOVES EAST ACROSS THE AREA THIS EVENING.
MEANWHILE...A COLD FRONTAL BOUNDARY WILL SAG SOUTHEAST TO THE OHIO
RIVER TOMORROW BEFORE DISSIPATING. THE NEXT MAIN FRONT WILL MOVE
IN MONDAY AND BRING A DRIER AIRMASS TO THE REGION FOR THE MIDDLE

&&

.NEAR TERM /THROUGH SUNDAY/...
AS OF 532 PM EDT SATURDAY...

A NEARLY SOLID LINE OF CONVECTION WILL CONTINUE TO MAKE ITS WAY
EASTWARD ACROSS THE FORECAST AREA. THE LATEST POSITION PLACES IT
FROM LYNCHBURG TO MARTINSVILLE. HAVE INCREASED POPS ACCORDING TO
AREAS ALONG AND EAST OF THIS LINE THROUGH THE EVENING HOURS. THE
REGION IMMEDIATELY BEHIND THE FRONT WILL BE STABLE FOR AN HOUR OR
TWO IN THE WAKE OF THE CONVECTION. BREAKS IN THE CLOUD COVER ABOUT
THREE HOURS OR SO BEHIND THE FRONT WILL ALLOW FOR A BIT MORE
HEATING HEADING INTO THE EVENING HOURS TO HELP TRIGGER SOME
ADDITIONAL SHOWERS AND MAYBE A THUNDERSTORM OR TWO PRIOR TO
SUNSET. WE ARE ALSO WATCHING AN AREA OF CONVECTION MOVING FROM
CENTRAL KY INTO EASTERN KY. THIS ACTIVITY...OR ITS DYING
REMNANTS...MAY REACH WESTERN PARTS OF OUR REGION LATE THIS

AS OF 305 PM EDT SATURDAY...

A SHORT WAVE CAME OUT OF WEST VIRGINIA THIS AFTERNOON TAPPING IN
TO A MOIST UNSTABLE ATMOSPHERE TO PRODUCE SOME STRONG TO SEVERE
WEATHER ACROSS THE AREA. THIS LINE MOVED ACROSS THE MOUNTAINS
EARLY THIS AFTERNOON AND IS AT THE BLUE RIDGE AT 400 PM. THIS LINE

WITH SOME DRY AIR ALOFT...STRAIGHT LINE WINDS IS THE PRIMARY
SEVERE THREAT. WITH ABUNDANT MOISTURE AND EFFICIENT
RAINFALL...AMOUNTS COULD TOTAL 1-3 INCHES IN AN HOUR. BLINDING
RAINFALL RATES OF 4-6 INCHES PER HOUR WILL QUICKLY FILL UP CREEKS
AND STREAMS AND POND WATER IN POOR DRAINAGE AND LOW LYING AREAS.

ONCE THE WAVE EXITS THIS EVENING...A SURFACE RIDGE WILL BUILD
OVER THE AREA AND INTO THE OHIO VALLEY THIS EVENING. THE LEE
TROUGH WILL REMAIN OVER THE PIEDMONT THROUGH TOMORROW. SHOWERS
WILL EXIT THE AREA OVERNIGHT WHILE DEBRIS CLOUDS LIMIT FOG
DEVELOPMENT.

A COLD FRONT WILL MOVE ACROSS THE NORTHERN MISSISSIPPI VALLEY
TOMORROW. A SIGNIFICANT PREFRONTAL SHORT WAVE IS EXPECTED TO TRACK
NORTHEAST ACROSS THE OHIO VALLEY. IF THE ENERGY FROM THIS SYSTEM
STAYS NORTH OF THE AREA...ONLY CHANCE-SCATTERED CONVECTION WILL
DEVELOP SUNDAY AFTERNOON. LOW LEVEL WINDS BACKS THROUGH THE DAY
WHILE JET DYNAMICS REMAIN VERY WEAK. THE AREAL COVERAGE OF STORMS
SHOULD BE GREATER SUNDAY AS THE FRONT APPROACHES THE TROPICAL-LIKE
UNSTABLE AIR MASS OVER THE REGION.

&&

.SHORT TERM /SUNDAY NIGHT THROUGH TUESDAY NIGHT/...
AS OF 400 PM EDT SATURDAY...

UPPER-LEVEL TROUGH WILL PUSH A COLD FRONT EAST INTO THE REGION ON
LABOR DAY. THIS FRONT WILL MOVE ACROSS OUR AREA MONDAY NIGHT INTO
TUESDAY. IN THE WAKE OF THE FRONT...CANADIAN HIGH PRESSURE WILL
BUILD SOUTH ACROSS OUR REGION TUESDAY AFTERNOON INTO TONIGHT.

SCATTERED SCATTERED SHOWERS AND THUNDERSTORMS WILL BE ONGOING
SUNDAY AFTERNOON INTO SUNDAY NIGHT. MOISTURE AND INSTABILITY
INCREASE WITH THE APPROACH OF THE COLD FRONT. SOME OF THE STORMS
COULD BE STRONG TO SEVERE WITH SOME HEATING/DESTABILIZATION.
LOCALLY HEAVY RAIN REMAINS POSSIBLE AS TROPICAL MOISTURE POOLS
ACROSS THE REGION AHEAD OF THE APPROACHING COLD FRONT...AND LIGHT
UPPER LEVEL WINDS WILL RESULT IN SLOW STORM MOVEMENT.

UNSETTLED WEATHER EXPECTED MONDAY....SIMILAR TO SUNDAY...WITH
SHOWERS AND THUNDERSTORMS DEVELOPING WITH AFTERNOON HEATING AS THE
COLD FRONT PROGRESSES EASTWARD. KEPT THE HIGHEST POPS IN THE WEST
AND TAPER OFF VALUES AS ONE HEAD SOUTHEAST ON MONDAY. MID AND
UPPER LEVEL WINDS TURN MORE WESTERLY AND DOWNSLOPE ON MONDAY
AFTERNOON...WHICH WILL BEGIN TO ACT AGAINST THE CONVECTION IN THE
PIEDMONTS. LOCALLY HEAVY RAIN AND A FEW STRONG STORMS WILL AGAIN
BE POSSIBLE INTO LATE MONDAY EVENING. THE DRIER AIR APPEARS TO BE
LAGGING BEHIND THE FRONT...SO ELECTED TO KEEP A FEW SHOWERS AND
THUNDERSTORMS ACROSS THE SOUTH TUESDAY AFTERNOON. ANY CONVECTION
WHICH FORMS WILL DIMINISH QUICKLY THURSDAY EVENING WITH THE LOSS
OF SOLAR HEATING. IN ENOUGH DRY AIR PUSHES SOUTH INTO OUR TO DROP
LOW TEMPERATURES TUESDAY NIGHT INTO THE UPPER 40S IN THE MOUNTAINS
TO THE LOWER 60S IN THE PIEDMONT.

&&

.LONG TERM /WEDNESDAY THROUGH SATURDAY/...
AS OF 400 PM EDT SATURDAY...

A STRONG RIDGE CONTINUES IN THE WEST...WHILE AMPLIFYING TROUGH
ANTICIPATED IN THE EAST. HIGH PRESSURE WILL CONTROL OUR WEATHER
PATTERN FOR WEDNESDAY AND THURSDAY...RESULTING IN DRY CONDITIONS
WITH MOSTLY CLEAR SKIES...OUTSIDE OF EARLY MORNING FOG. ANOTHER
COLD FRONT WILL DROP SOUTHEAST ACROSS THE REGION FRIDAY WITH SOME
MOISTURE AND INSTABILITY...KEPT THE MENTION OF ISOLATED TO
SCATTERED SHOWERS WITH FRONTAL BOUNDARY. ISOLATED AFTERNOON
CONVECTION IS POSSIBLE SATURDAY AFTERNOON WITH BEST CHANCES ACROSS
THE HIGHER TERRAIN. TEMPERATURES INITIALLY START BELOW NORMAL THEN
SLOWLY MODERATE INTO THE WEEKEND.

&&

.AVIATION /22Z SATURDAY THROUGH THURSDAY/...
AS OF 115 PM EDT SATURDAY...

CONVECTION IS TRACKING SOUTHEAST ALONG A WARM FRONT THIS
AFTERNOON. MAIN CONVECTION IS TRACKING ACROSS WESTERN KENTUCKY AND
MAY STAY SOUTH OF THE AREA. HOWEVER NEW DEVELOP FROM OUTFLOW
BOUNDARIES WILL DISRUPT TRAVEL ACROSS EXTREME SW VA THROUGH EARLY
THIS AFTERNOON. BLUEFIELD IS THE ONLY AIRPORT IN THE PATH OF THESE
STORMS. THESE THUNDERSTORMS WILL IMPACT BLF THROUGH 19Z
TODAY...THEN LIGHT SHOWERS UNTIL SUNSET. THUNDERSTORM COVERAGE
APPEARS TO BE TRACKING TO THE EAST-SOUTHEAST STAYING SOUTH BCB/ROA
THROUGH MID AFTERNOON. OUTFLOW BOUNDARIES WILL LIKELY BRING
CONVECTION OVER THESE AIRPORTS THIS AFTERNOON. TIMING AND
CONFIDENCE IN QUESTION...THEREFORE WILL KEEP VCTS FOR NOW AND
AMEND IF NEEDED. LYH/DAN MAY ALSO SEE A FEW STORMS LATE THIS
AFTERNOON INTO THIS EVENING. CONFIDENCE IS LOW ON TIMING AND AREAL
COVERAGE TO ALSO ONLY HAVE VICINITY WORDING.

LOOKS LIKE THE SHOWERS/STORMS WANE OVERALL THIS EVENING WITH LOSS
OF HEATING AND BEING BETWEEN TWO UPPER WAVES. NEXT WAVE ARRIVES
SUNDAY WITH ANOTHER THREAT OF STORMS...EVEN HIGHER AS FRONT
