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

Fort Worth, TX (KFWD), launched 12:00Z, 1.1 hours before the alert went out and 166 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.

What forecasters said that day

The local office's own words before this severe thunderstorm warning went out, as it sent them, from the Iowa Environmental Mesonet's archive of National Weather Service text.

NWS Fort Worth, TX wrote its last area forecast discussion before this severe thunderstorm warning went out at Jun 14, 6:35 AM CDT, 1 hour 31 minutes earlier.

Area forecast discussion, Jun 14, 6:35 AM CDT, 1 hour 31 minutes before

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE FORT WORTH TX
635 AM CDT THU JUN 14 2012

.AVIATION...
CONVECTION SHOULD REMAIN EAST OF TAF SITES TODAY AS LINGERING
BOUNDARY HEADS OFF TO THE NORTHEAST. THUS CHANCE OF CONVECTION
OCCURRING AT TAF SITES IS TOO LOW TO MENTION.

VFR IS EXPECTED AT METROPLEX TAF SITES THROUGH THIS EVENING. MVFR
STRATUS AT 015 IS LOCATED TO THE SOUTH THIS MORNING AND SHOULD
STAY SOUTHEAST OF TAF SITES...BUT MAY BRIEFLY IMPACT GKY/DAL.
SOUTH WINDS 10-15KT WILL PREVAIL. A ROUND OF MVFR STRATUS IS
EXPECTED LATE TONIGHT AROUND 10Z.

FOR WACO...STRATUS SHOULD CONTINUE THROUGH 15Z OR SO BEFORE
LIFTING. VFR WITH SOUTH WINDS AT 10-15KT WILL PREVAIL THROUGH
THIS EVENING...BUT EXPECT STRATUS AGAIN LATE TONIGHT AROUND 10Z.

&&

.PREV DISCUSSION... /ISSUED 305 AM CDT THU JUN 14 2012/
ATMOSPHERE REFUSES TO STABILIZE...AS MODELS HAVE TRIED TO
FORECAST FOR A COUPLE OF DAYS NOW. GUIDANCE NOW HOLDS SOME
INSTABILITY AND LOW PRECIP CHANCES IN THEIR OUTPUT THROUGH
THURSDAY NIGHT AND THAT IS WHAT I AM FORECASTING.

FOR THIS MORNING...A WEAK BOUNDARY OR FRONT REMAINS DRAPED ACROSS
NORTH TEXAS...RUNNING GENERALLY FROM PALESTINE TO EASTLAND. A FEW
STORMS HAVE FIRED IN NORTHWEST COUNTIES...BUT SEEM TO BE
WEAKENING. AN AREA OF CONVECTION IN THE EAST...CENTERED BETWEEN
ATHENS AND FAIRFIELD...HAS BECOME LARGER IN THE LAST FEW HOURS.
NO ORGANIZED SEVERE WEATHER IS EXPECTED...BUT SEVERE WARNINGS
WERE ISSUED EARLIER TONIGHT FOR STORMS FARTHER SOUTHEAST NEAR
CROCKETT. I HAVE ADDED SLIGHT CHANCE POPS FOR TODAY NORTHEAST OF
A LINE FROM GRAHAM TO LEONA...AND CONTINUED POPS IN THE
NORTHEASTERN HALF OF NORTH TEXAS THROUGH MIDNIGHT.

RIDGING IS STILL PROGGED TO MOVE ACROSS THE AREA FRIDAY THROUGH
MONDAY...BUT BY TUESDAY AN INVERTED TROF...EXTENDING NORTH FROM A
TROPICAL DISTURBANCE IN THE GULF...WILL WEAKEN THE RIDGE AND MAY
PROVIDE SOME CONVECTIVE POTENTIAL. I HAVE ADDED LOW POPS
WEDNESDAY IN THE EAST AS A RESULT.

WITH SOUTH FLOW EXPECTED ALL WEEK...I AM STILL FORECASTING
SEASONABLY WARM TEMPERATURES...LOWS IN THE 70S AND HIGHS IN THE
UPPER 80S/LOW 90S. SINCE THE RIDGE IS NOT PROGGED TO BE AS STRONG
AS THE USUAL MID-SUMMER //DEATH RIDGE//...THIS SHOULD LIMIT THE
INVERSION STRENGTH AND THUS THE POTENTIAL FOR VERY HIGH AFTERNOON
TEMPERATURES.
