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.

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 North Platte, NE wrote its last area forecast discussion before this severe thunderstorm warning went out at Jul 8, 2:45 PM MDT, 2 hours 41 minutes earlier.

Area forecast discussion, Jul 8, 2:45 PM MDT, 2 hours 41 minutes before

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE NORTH PLATTE NE
345 PM CDT FRI JUL 8 2011

.SYNOPSIS...
A SURFACE HIGH OVER IOWA THIS MORNING MOVED EAST TODAY AND ALLOWED A
SURFACE TROUGH TO ENTER WESTERN PORTION OF THE STATE. ABUNDANT
MOISTURE AND WEAK INSTABILITY LAY OVER MUCH OF THE REGION THIS
MORNING. WEAK CONVECTION MOVED ACROSS KANSAS AND SOUTHERN NEBRASKA
BUT RESULTED ONLY IN CLOUD COVER AND A FEW SHOWERS. A SLIGHTLY
STRONGER SHORT WAVE NOW OVER COLORADO WILL MOVE INTO WESTERN
NEBRASKA LATER TONIGHT AND BRING. THUNDERSTORMS...SOME SEVERE...ARE
OCCURRING NOW ACROSS THE FRONT RANGE AND THAT CONVECTION WILL
SPREADS INTO NEBRASKA THIS AFTERNOON WELL AHEAD OF THE SHORT WAVE.

THE OVERALL WEATHER PATTERN INTO NEXT WEEK CENTERS ON A THERMAL
RIDGE ACROSS THE CENTRAL PLAINS.  THIS AXIS THEN SHIFTS EAST AND
ALLOWS A SLIGHT SOUTHWEST FLOW OVERHEAD.  SOUTHWEST FLOW WILL THEN
BRING IN HIGH IN PRECIPITABLE WATER AIR OVER THE STATE. ALL MODELS
AGREE WITH THIS PATTERN.  AS A PERCENTAGE OF NORMAL THE AIR MASS
COMING OUT OF THE SOUTHWEST WILL AVERAGE 125% OF NORMAL AND MORE AND
THIS WILL CREATE POTENTIAL FLOODING CONCERNS OVER THE NEXT WEEK FROM
ANY THUNDERSTORMS WHICH DO DEVELOP.  THE WEATHER FORECAST CALLS FOR
AN ACTIVE PATTERN WITH THE CHANCE OF THUNDERSTORMS NEARLY EACH DAY
AND NIGHT THOUGH IT WILL BE IMPOSSIBLE TO PINPOINT WHICH SPECIFIC
AREA IS MOST LIKELY TO RECEIVE THE RAINFALL OUTSIDE OF 12-24
HOURS.

&&

.SHORT TERM...TONIGHT THROUGH 00Z SATURDAY

ONGOING CONVECTION OVER THE WESTERN PANHANDLE INTO CENTRAL COLORADO
WILL MOVE EAST THIS EVENING. INSTABILITY ACROSS THE AREA WILL BE
HIGHEST THE PANHANDLE AND INTO WESTERN NEBRASKA BUT WILL WANE GOING
EAST. MAIN FORCING WITH UPPER LEVEL SHORTWAVE TROUGH WAS AND WILL BE
FOCUSED OVER NORTH DAKOTA AS IS THE MOISTURE TRANSPORT SO BELIEVE
AS DAYTIME HEATING DIMINISHES AND STORMS MOVE INTO MORE STABLE
AIR AND WILL DIMINISH. MAY GET A FEW STORMS IN THE FORECAST AREA...
BUT NOT EXPECTING WIDESPREAD ACTIVITY THIS EVENING. AS FOR SEVERE
CHANCES...DEEP LAYER SHEAR IN THE FORECAST AREA IS MARGINAL RIGHT
AWAY BUT DOES INCREASE TO AROUND 40 TO 45KTS BY 06Z. WILL KEEP AN
EYE ON THINGS FOR STRONG STORMS IN THE WESTERN PARTS OF THE FORECAST
AREA TONIGHT.

A SURFACE BOUNDARY WITH DRIER AIR AND WESTERLY WINDS ON THE BACKSIDE
WILL BE LOCATED ROUGHLY FROM SOUTHWEST INTO NORTH CENTRAL NEBRASKA
ON SATURDAY MORNING AND WILL STAY IN THE GENERAL VICINITY THROUGH
THE DAY. THIS BOUNDARY WILL SERVE AS FOCUS FOR THE DEVELOPMENT OF
SOME SCATTERED THUNDERSTORMS IN THE AFTERNOON. LIFTED INDEX VALUES
OF MINUS 8 ARE FORECAST AND NAM INDICATING AMOUNTS OF AROUND 2500
J/KG ML CAPE EAST OF THE BOUNDARY BUT NOT A GOOD FORCING SIGNAL WITH
ONLY VERY WEAK WAVES OF ENERGY MOVING THROUGH THE UPPER LEVEL FLOW.
CONVECTION WILL FIRE WITH HELP OF DAYTIME HEATING ALONG THE
BOUNDARY IN THE AFTERNOON...AND WITH THE LITTLE FORCING SHOULD BE
MORE SCATTERED THAN WIDESPREAD COVERAGE AND HAVE GRIDS INDICATING
THAT. WHERE THERE ARE STORMS COULD GET SOME STRONGER TO POSSIBLY
SEVERE STORMS AS DEEP LAYER SHEAR WOULD BE STRONG ENOUGH FOR
ORGANIZED CONVECTION. TEMPERATURES ARE ALSO SOMETHING TO LOOK AT.
SOME GUIDANCE SHOWS MID 90S ACROSS THE AREA AND DO THINK IT WILL BE
A WARM DAY BUT THAT MAY BE PUSHING IT A BIT. TO CONTEND WITH MAY BE
SOME CLOUD COVER WITH BOUNDARY IN THE VICINITY. TO THE WEST OF THE
BOUNDARY THE AIR WILL BE DRIER SO EXPECTING HIGHER MIXING AND WITH
850MB TEMPERATURES WARMING TO 28-29C BY 00Z SUNDAY SHOULD BE ABLE TO
REACH LOW 90S IN THOSE LOCATIONS.

SUNDAY...THE FRONT LAY JUST SOUTH AND EAST OF THE AREA BUT MIX BACK
ACROSS THE CWA DURING THE DAY. SEVERE THUNDERSTORMS ARE AGAIN
POSSIBLE ON SUNDAY BY 0Z. CAPES AGAIN REACH AROUND 2500 J/KG BUT WE
ARE ALSO TROUBLED BY HIGH FREEZING LEVELS/WET BULB ZEROS 16184 FEET
/ 14457 FEET.  STORM MOTION WILL BE EAST AT 16 KNOTS BUT WITH K
INDEX VALUES OVER 40 AND PRECIPITABLE WATER VALUES AGAIN OVER 1.50
INCHES AND PERCENT NORMALS GREATER THAN 130.

&&

.AVIATION

MAIN AVIATION CONCERNS THROUGH 18Z SATURDAY DEAL WITH WINDS ALONG
WITH CHANCES FOR CONVECTION THIS EVENING AND OVERNIGHT. BREEZY
SOUTHERLY WINDS WILL SUBSIDE THIS EVENING AS MIXING DECREASES AND A
GRADUAL SHIFT TO THE SOUTHWEST THEN TO THE WEST BY THE END OF THE
PERIOD AS A FRONT OFF TO THE WEST SLOWLY MOVES INTO THE AREA.

THUNDERSTORMS ARE POSSIBLE...THOUGH NOT PROBABLE AT BOTH KVTN AND
KLBF TONIGHT. CONVECTION IS ONGOING TO THE WEST ACROSS THE WESTERN
NEBRASKA PANHANDLE THIS AFTERNOON...BUT THE ENVIRONMENT BECOMES MORE
UNFAVORABLE FOR THUNDERSTORMS GOING TO THE EAST INTO CENTRAL
NEBRASKA. ALSO...THE BULK OF THE FORCING SIGNALS STAY TO THE NORTH
OF THE FORECAST AREA SO AS DAYTIME HEATING GOES AWAY...THERE
SHOULDN/T BE MUCH TO FUEL THE ONGOING STORMS AND DON/T EXPECT THE
ACTIVITY TO MAKE IT TOO FAR EAST. SO ALTHOUGH MAY GET SOME STORMS IN
THE REGION...NOT EXPECTING WIDESPREAD THUNDERSTORM ACTIVITY AND
DIDN/T HAVE THE CONFIDENCE TO ADD BEYONE CB INTO THE FORECAST. INTO
THE DAY ON SATURDAY...THE FRONT WILL BE IN THE VICINITY OF THE LOCAL
AREA. THERE WILL AGAIN BE CHANCES FOR CONVECTION...BUT BELIEVE
THINGS WILL HOLD OFF UNTIL AFTERNOON TO DEVELOP ALONG THE FRONT.
