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 tornado 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, 9.5 hours before the alert went out and 86 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 12, 3:43 PM EDT, 1 hour 47 minutes before

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE BLACKSBURG VA
343 PM EDT SUN JUL 12 2009

.SYNOPSIS...
A COLD FRONT WILL CROSS THE FORECAST AREA LATE THIS AFTERNOON...THEN
STALL JUST TO OUR SOUTH TONIGHT. A WEAK AREA OF HIGH PRESSURE WILL
MOVE ACROSS THE OHIO VALLEY MONDAY...CROSSING THE CENTRAL
APPALACHIANS TUESDAY. THE STALLED FRONT TO OUR SOUTHWEST WILL
RETURN AS A WARM FRONT WEDNESDAY...FOLLOWED BY ANOTHER COLD FRONT
THAT WILL CROSS THE OHIO VALLEY WEDNESDAY AND INTO OUR FORECAST
AREA BY THURSDAY.

&&

.NEAR TERM /THROUGH MONDAY/...
THE COLD FRONT WILL SLIDE INTO NORTH CAROLINA OVERNIGHT WHILE THE
THETA-E BOUNDARY IS DRAPED OVER THE AREA. WITH SOME CLEARING
OVERNIGHT AND SATURATED LOW LEVELS...FOG IS LIKELY ACROSS THE AREA
ESPECIALLY IN MOUNTAIN VALLEYS. CONVECTION THIS EVENING WILL BE
WANING AFTER SUNSET AND BASED ON RNK LOCAL WRF...SHOULD END OR EXIT
THE AREA AROUND 03Z. ON MONDAY...THETA-E AXIS SPLITS THE AREA AND
WITH AFTERNOON HEATING...SCATTERED SHOWERS AND THUNDERSTORMS ARE
POSSIBLE ACROSS THE SOUTHERN TIER OF CWA (BLF-ROA-DAN). TO THE
NORTH...DRIER AIR WILL KEEP THESE COUNTIES DRY. WILL ADD ISOLATED
SHOWERS TO THE NORTH FOR GOOD MEASURE AND IN CASE THETA-E BOUNDARY
DOES RETREAT TO THE NORTH WITH THE DEVELOPMENT OF A WEAK SURFACE
REFLECTION EAST OF THE BLUE RIDGE.

MUGGY CONDITIONS ARE EXPECTED TONIGHT WITH READINGS IN THE 60S.
TEMPERATURES MONDAY WILL BE SIMILAR TO TODAY BUT LESS STICKY WITH
DRIER AIR COMING IN FROM THE NORTH.

NOTE...THE ZFP WILL STILL CARRY AFTERNOON WORDING SINCE MOST OF THE
CONVECTION WILL BE THIS AFTERNOON AND EVENING.

&&

.SHORT TERM /MONDAY NIGHT THROUGH WEDNESDAY/...
HIGH PRESSURE AND A DRIER AIRMASS BUILD IN FOR MONDAY NIGHT AND
TUESDAY. WILL KEEP THE FORECAST DRY FOR TUESDAY. WENT CLOSE TO BIAS
CORRECTED MOS GRIDS FOR HIGH TEMPERATURES TUESDAY SINCE GUIDANCE HAS
OVERALL BEEN TOO WARM WITH HIGHS...ESPECIALLY BEHIND A FRONT. THE
HIGH MOVES FAR ENOUGH EAST BY WEDNESDAY AND A WEAK WARM FRONT COMES
THROUGH...PUTTING THE FORECAST AREA BACK IN THE WARM SECTOR. THERE
SHOULD BE ENOUGH INSTABILITY AND MOISTURE BY WEDNESDAY AFTERNOON FOR
ISOLATED TO SCATTERED THUNDERSTORMS.

&&

.LONG TERM /WEDNESDAY NIGHT THROUGH SUNDAY/...

DIGGING IN THE NORTHEAST ON THE ECMWF AND FOLLOWS ROUGHLY ALONG
WITH HPC GUIDANCE.

&&

.AVIATION /20Z SUNDAY THROUGH FRIDAY/...
FRONTAL BOUNDARY WILL BE IN THE NORTHERN PORTION OF RNK CWA THIS
AFTERNOON AND WITH THE ADDITION OF A LEE TROUGH AND AFTERNOON
HEATING...SCATTERED CONVECTION IS A GOOD BET. MORNING LOW CLOUDS
HAVE LIFTED TO VFR LEVELS ACROSS THE WEST BUT MAY LOWER TO MVFR IF
HIT WITH PASSING SHOWERS.

SCATTERED SHOWERS AND THUNDERSTORMS ARE ANTICIPATED FOR THE
AFTERNOON AND EARLY EVENING. WITH COVERAGE SCATTERED ABOUT...WILL
ONLY HAVE VICINITY CODING IN THE TAFS. IF A SHOWER OR THUNDERSTORMS
LOOKS TO HIT ANY TAF SITES...WILL AMEND.

CLEARING BEHIND THE FRONT WILL BRING OPPORTUNITY FOR RADIATION FOG
TONIGHT...ESPECIALLY IN THE MOUNTAIN VALLEYS. A WESTERLY UPSLOPE
WIND WILL ALSO PERSIST WEST OF THE MOUNTAINS...SO FEEL MVFR TO IFR
CONDITIONS WILL REDEVELOP AT KBLF/KLWB AGAIN TONIGHT.
