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.

Area forecast discussion, Jun 13, 1:08 PM CDT, 4 hours 54 minutes before

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE AMARILLO TX
108 PM CDT FRI JUN 13 2003

BASED ON GOES-WEST RAPID SCAN VIS SAT IMAGERY AND REGIONAL SFC OBS
INCLUDING THE OK/TX/WTX PNHDL SCHOOL NET/MESONETS...NUMEROUS OUTFLOW
BOUNDARIES ARE IN PLACE ACROSS THE REGION AND ARE THE PRIMARY
MECHANISM FOR THE AMPLE MOISTURE OVER THE PNHDLS AND ERN NM.  AS OF
17Z A DL HAD DEVELOPED AND WAS LOCATED IN THE PERMIAN BASIN AND
EXTENDED SOUTH. SOUTHEAST BOUNDARY LAYER FLOW WILL CONTINUE TO ADVECT
MOISTURE INTO THE PNHDLS THROUGH TONIGHT AS A SERIES OF WEAK S-W
TROUGHS MOVE OVER THE REGION. DEEP MOIST CONVECTION THAT DEVELOPS
THIS AFTERNOON AND EVENING SHOULD CONTINUE THROUGH MUCH OF THE NIGHT
ESPECIALLY OVER THE SE PORTION OF THE CWA. HODOGRAPHS DERIVED FROM
REGIONAL PROFILER DATA INDICATE THE GREATER 0-6 KM SHEARS AND HODO
LENGTHS EXIST SOUTH OF THE CWA. HAIL APPEARS TO BE THE MAIN THREAT
FROM THE STRONGEST ACTIVITY TONIGHT IN THE AMA CWA. I EXPANDED THE
LIKELY POPS TO INCLUDE THE ENTIRE CWA FOR TONIGHT.

LOW CLOUDS/CONVECTIVE DEBRIS WILL BE SLOW TO MIX OUT TOMORROW BUT
HIGH TEMPS SHOULD REACH INTO THE 80S. WARM TEMPS AND AMPLE MOISTURE
COMBINED WITH A WEAK UPR LVL LOW WILL ALLOW FOR MORE DEEP MOIST
CONVECTION TO DEVELOP IN THE AFTERNOON/EVENING BUT COVERAGE APPEARS
TO BE MORE LIMITED COMPARED TO TODAY/TONIGHT...30 POPS FOR NOW. THE
UPR LVL LOW WILL MEANDER TO OUR EAST KEEPING THE REGION UNSETTLED
AGAIN ON SUNDAY.

FOR NEXT WEEK...UPR LVL L-W RIDGING BUILDS OVER THE WRN U.S. PLACING
THE CWA UNDER THE ERN RIM OF THE RIDGE AND HENCE UNDER NORTHERLY
MID/UPR LVL FLOW. SEVERAL WEAK DISTURBANCES COMBINED WITH AFTERNOON
HEATING NECESSITATE LOW POPS EACH DAY THROUGH WED. KEPT THR AND FRI
DRY FOR NOW.
