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 12:00Z, 9.3 hours before the alert went out and 36 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, Jul 21, 2:36 PM EDT, 2 hours 39 minutes before

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE BLACKSBURG VA
236 PM EDT SAT JUL 21 2012

.SYNOPSIS...
A FRONTAL BOUNDARY WILL LINGER IN NORTH CAROLINA INTO SUNDAY
BEFORE DISSIPATING. THERE WILL BE A FEW DISTURBANCES MOVING IN
FROM TIME TO TIME INTO TUESDAY KEEPING THE THREAT OF STORMS
AROUND.

&&

.NEAR TERM /THROUGH SUNDAY/...
AS OF 225 PM EDT SATURDAY...

AN UPPER LEVEL RIDGE IS STRETCHED FROM THE CENTRAL PLAINS EAST INTO
THE OHIO VALLEY. ANOTHER RIDGE IS STRETCHED FROM BERMUDA BACK INTO
SOUTHEASTERN COASTAL STATES. IN BETWEEN THESE TWO RIDGES AND OVER
THE MID ATLANTIC/TENNESSEE VALLEY IS A WEAK UPPER LEVEL TROUGH. ALSO
DRAPED OVER THE REGION IS A WEAK SURFACE BOUNDARY. COUPLED WITH THE
TROUGH AND BOUNDARY...CONVERGENCE AND DAYTIME HEATING WILL BRING
SCATTERED SHOWERS AND THUNDERSTORMS TO THE AREA THIS AFTERNOON AND
EVENING. A FEW OF THESE STORMS MAY BECOME SEVERE EAST OF THE BLUE
RIDGE TOWARD THE NC/VA BORDER SOUTH. PWATS ARE 1.50-2.00 INCHES AND
STEERING CURRENTS ARE WEAK. THEREFORE...ANY STORM THIS AFTERNOON
WILL ALSO HAVE THE POTENTIAL TO DROP 1-3 INCHES OF RAIN.

OVERNIGHT...SHOWERS WILL FADE AND WEAK HIGH PRESSURE/WEDGE BUILDS
OVER THE AREA. ISENTROPIC LIFT INCREASES IN THIS MOIST ATMOSPHERE
FOR AREAS ALONG AND EAST OF THE BLUE RIDGE TO SEE LIGHT RAIN/DRIZZLE
DURING THE EARLY MORNING HOURS SUNDAY. IF DRIZZLE OR RAIN DOES NOT
FALL...THESE AREA WILL LIKELY SEE DENSE FOG IN THE MORNING.

THE UPPER LEVEL RIDGES WILL REMAIN IN THEIR RESPECTED AREAS WHILE
THE TROUGH WEAKENS OVER THE REGION. THE SURFACE BOUNDARY SHOULD
DRIFT FARTHER SOUTH IN TO THE CAROLINAS SUNDAY. WITH AFTERNOON
HEATING AND TROUGHINESS ALOFT...ISOLATED SHOWERS AND THUNDERSTORMS
ARE POSSIBLE...MAINLY SOUTH.

THE WEDGE WILL ERODE BY THE AFTERNOON. TEMPERATURES SHOULD REBOUND
QUICKLY AND LEVEL OFF NEAR NORMAL.

&&

.SHORT TERM /SUNDAY NIGHT THROUGH TUESDAY NIGHT/...
AS OF 200 PM EDT SATURDAY...

WILL USE A MODEL BLEND OF THE 00Z ECMWF/12Z GFS/09Z SREF THIS
PERIOD. THE MAIN ISSUE WILL BE SHORTWAVES FLOWING IN THE NW FLOW
ALOFT AND HOW STRONG ANY MCS UPSTREAM GETS AND HOW FAR EAST IT CAN
MAKE IT. THE ECMWF IS ADVERTISING A QUICKER MOVEMENT TO ONE WAVE
COMING ACROSS THE NRN TIER OF THE CWA MON MORNING EARLY THEN OUT TO
THE COAST IN THE AFTN...WHILE THE GFS IS SLOWER/WEAKER. WILL KEEP
POPS IN THE CHANCE RANGE WITH HIGHEST OVER THE NW AND SW...WITH
MODEST THETA-E RIDGING IN THE MTNS AND ANOTHER WEAKER SHORTWAVE
SHOWING UP IN THE AFTN.

AREA TO STAY INT HE WARM SECTOR THIS PERIOD WITH FRONTAL BOUNDARY
LINGERING MORE OVER THE SRN GREAT LAKES INTO MID ATLANTIC...BUT WILL
STILL SEE STORMS OFF AND ON THROUGH TUE NIGHT. MODELS SEEM TO BE IN
BETTER AGREEMENT INTO TUESDAY WITH PRECIP BUT DIFFERENCES EXIST ON
THE INDIVIDUAL VORTS. THE NAM/ECMWF SHOWING THE MAIN TRACK TUE FROM
THE SRN GREAT LAKES 12Z TUE TO NRN VA/MID ATLANTIC...WHILE WEAKER
SHORTWAVE SHIFTS ACROSS THE TN VALLEY. THE GFS ON THE OTHER HAND
BRINGS THE NRN WAVE IN QUICKER AND OUT TO SEA BY 18Z TUE WITH NEXT
TWO WAVES LINED UP FROM INDIANA TO ERN KY BY THE END OF THE DAY. FOR
NOW IT STILL LOOKS LIKE THE POPS CAN BE KEPT IN THE CHANCE
RANGE...BUT THINK THE NRN AND WRN CWA COULD SEE A BETTER THREAT BY
TUESDAY AFTN.

TEMPS THIS PERIOD WERE KEPT JUST A DEGREE OR TWO COOLER THINKING
MORE CLOUD COVER AND CONVECTION MAY KEEP TEMPS DOWN...HOWEVER
TUESDAY SHOULD BE HOT AS THE WRLY FLOW WILL BE STRONGER AND IF THE
SUN STAYS OUT LONGER...THE PIEDMONT COULD SOAR TOWARD THE CENTURY
MARK...BUT COULD ALSO SEE A LITTLE LOWER DEWPOINTS. FOR NOW STICKING
WITH MID 90S EAST TO MID TO UPPER 80S WEST.

&&

.LONG TERM /WEDNESDAY THROUGH SATURDAY/...
AS OF 1222 PM EDT SATURDAY...

LOOKS LIKE WE WILL BE STUCK IN A HUMID SOMEWHAT STORMY BUT TYPICAL
LATE JULY PATTERN WITH THE RIDGE STAYING RIGHT ON THE SWRN DOORSTEP
OF OUR REGION...WITH THE BLACKSBURG FORECAST AREA REMAINING ON THE
SRN FRINGE OF THE TROUGH OVER THE NORTHEAST.

WILL BE GOING WITH DAILY THREAT OF SHRA/TSRA BUT WILL SEE ENHANCED
PROBABILITIES AS A SERIES OF SHORTWAVES GRAZE BY...BUT TIMING AT
THIS POINT IS UP IN THE AIR...WITH FRONTAL BOUNDARY SWINGING TOWARD
US IN THE WED-THU TIME FRAME THEN LIFTING NORTH AGAIN BY THE WEEKEND.

LOWS AT NIGHT WILL STAY IN THE 60S IN THE MTNS WITH LOWER 70S EAST
WITH HIGHS IN THE MID-UPPER 80S MTNS TO LOWER TO MID 90S EAST. OF
COURSE ANY CONVECTION AND OR BLOWOFF OF STORMS WILL LIMIT SOME
HEATING FROM TIME TO TIME DURING THE DAY.

&&

.AVIATION /19Z SATURDAY THROUGH THURSDAY/...
AS OF 1257 AM EDT SATURDAY...

THE FRONT SINKS SOUTH TONIGHT. BEHIND THE FRONT...COOL EASTERLY FLOW
BEING OVERRUN BY MOIST WESTERLY FLOW ALOFT. WITH AN INCREASE IN
ISENTROPIC LIFT...LOWER OF THE CLOUD DECK BELOW MVFR WITH AREAS OF
DRIZZLE IS HIGHLY LIKELY ESPECIALLY NORTH OF HWY 460
(LYH-ROA-BCB-LWB). THESE CLOUDS MAY NOT LIFT UNTIL MID MORNING
SUNDAY. BLF LOOKS TO KEEP A MOIST WEST WIND OVERNIGHT. UPSLOPE
ENHANCEMENT AT BLF WILL KEEP LIFR CEILINGS DEEP INTO SUNDAY MORNING.

ONCE CLOUDS BURN OFF...AN UPPER LEVEL TROUGH AND AFTERNOON HEATING
MAY GENERATE AN ISOLATED SHOWER OR THUNDERSTORMS SUNDAY AFTERNOON.
FOG MAY BE PROBLEMATIC ACROSS THE MOUNTAIN VALLEYS SUNDAY NIGHT INTO
MONDAY MORNING.

NW FLOW ALOFT LOOKS TO PERSIST MONDAY INTO WEDNESDAY...POSSIBLY
RESULTING IN OF SHRA/TSRA THRU THE PERIOD. OTHERWISE EXPECTING
VFR OUTSIDE OF ANY PERIODS OF THUNDERSTORMS...AND CONTINUED LATE
NIGHT FOG THROUGH MID WEEK.
