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

Shreveport, LA (KBAD), launched 12:00Z, 11.0 hours before the alert went out and 140 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 10, 2:39 PM CDT, 3 hours 19 minutes before

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE LITTLE ROCK AR
239 PM CDT THU JUL 10 2014

.DISCUSSION...

MAIN CONCERNS THIS FORECAST CYCLE ARE CHANCES OF CONVECTION TODAY
THROUGH FRIDAY...THEN THE OVERALL CHANCE LOWERS AS THE UPPER HIGH
PRESSURE RIDGE BUILDS IN MORE OVER THE AREA. TEMPERATURES WILL
GRADUALLY INCREASE REACHING THE 90S OVER THE WEEKEND...AS WELL AS
HEAT INDEX VALUES IN THE 90S.

CURRENT TSTORM COMPLEX SLOWLY MOVING ESE INTO NW AR...WITH THE MAIN
CORE ALONG THE I40 CORRIDOR. HAS PULSED UP AND DOWN A BIT AND MAY
SEE A WARNING OR TWO WITH IT AS IT MOVES ACROSS NORTH CENTRAL AR.
ALSO OTHER SCATTERED CONVECTION WAS DEVELOPING OVER WESTERN AR IN
THE HEATING OF THE DAY...BUT WILL BE MORE ISOLATED. EXPECT AFTER
SUNSET FOR CONVECTION THE GRADUALLY WEAKEN AND DISSIPATE. THE
FRONT HAS BECOME MORE WASHED OUT AND NEARLY STATIONARY...WITH SOME
ANALYSIS OVER NORTH CENTRAL AR...WITH DEW POINT TEMPS IN THE 60S
NORTH OF THE BOUNDARY WHILE IN THE 70S SOUTH. TEMPS WERE BEING
HELD DOWN THIS AFTERNOON IN CLOUDS AND CONVECTION AREAS...WHILE IN
THE 80S ELSEWHERE. 12Z KLZK SOUNDING HAD A MOIST LOWER SURFACE TO
8K FEET LAYER..WITH PRECIP WATER VALUE OF 1.13 INCHES...WHILE
ABOVE 8K FEET QUITE DRY. THIS SHOULD LIMIT CONVECTION A BIT BUT
NOT ENOUGH TO STOP IT. DID UPDATE FORECAST A BIT EARLIER TO FINE
TUNE ON GOING POPS...ESPECIALLY OVER THE NORTH CENTRAL. THE UPPER
NW FLOW IS EXPECTED TO TAKE THE CURRENT CONVECTION MORE ESE.

&&

.SHORT TERM...TONIGHT THROUGH SUNDAY NIGHT

WILL START THE FORECAST WITH LIKELY POPS ASSOCIATED WITH THE WEAK
MCS MOVING ACROSS AR...WHILE CHANCE TO SLIGHT CHANCE OVER THE REST
OF THE STATE. AFTER SUNSET...CONVECTION SHOULD GRADUALLY WIND
DOWN...WHILE THE REMNANTS OF THE MCS COULD LINGER UNTIL IT MOVES
OUT OF AR. THEN DRY OVERNIGHT WITH SOME PATCHY FOG IN THOSE AREA
THAT HAD RAIN WITH MILD LOWS IN THE 70S. ON FRIDAY...500MB HEIGHTS
ARE FORECAST TO BUILD INTO THE REGION FROM THE WEST AS THE UPPER
HIGH PRESSURE RIDGE BUILDS IN OVER AR. THIS WILL BEGIN PUTTING A
CAP ON THE CONVECTION POTENTIAL ON FRIDAY AND OVER THE WEEKEND.
TEMPERATURES WILL ALSO BEGIN WARMING AND REACHING THE 90S OVER THE
WEEKEND...WITH SOME HEAT INDEX VALUES APPROACHING 100 DEGREES.

&&

.LONG TERM...MONDAY THROUGH THURSDAY

NORTHWEST FLOW WILL BE OVER ARKANSAS THROUGH THE PERIOD. HIGH
PRESSURE ALOFT WILL BE OVER THE WESTERN U.S. AND AN AREA OF LOW
PRESSURE WILL BE OVER THE GREAT LAKES. THE UPPER TROUGH WILL DIG
INTO ARKANSAS WEDNESDAY AND THURSDAY...BRINGING COOLER WEATHER.

A COLD FRONT WILL BRING A CHANCE OF SHOWERS AND THUNDERSTORMS LATE
MONDAY AFTERNOON THROUGH EARLY WEDNESDAY. MODELS INDICATE THE FRONT
MOVING SOUTH OUT OF THE STATE WEDNESDAY MORNING. HIGH PRESSURE WILL
BUILD IN BEHIND THE FRONT WITH COOLER AIR. TEMPERATURES WILL BE NEAR
NORMAL MONDAY...BUT BELOW NORMAL TEMPERATURES ARE EXPECTED TUESDAY
THROUGH THURSDAY.

500 AM CDT THU JUL 10 2014

THIS HAZARDOUS WEATHER OUTLOOK IS FOR A LARGE PART OF ARKANSAS.

.DAY ONE...TODAY AND TONIGHT

A STATIONARY FRONTAL BOUNDARY...NEAR THE LOUISIANA BORDER...WILL
CONTINUE TO PROVIDE A FOCUS FOR SCATTERED SHOWERS AND THUNDERSTORMS
TODAY AND TONIGHT. WHILE A FEW STRONG STORMS ARE POSSIBLE...THE
CHANCES OF ORGANIZED SEVERE WEATHER WILL BE LOW.

MEANWHILE...A COMPLEX OF THUNDERSTORMS ACROSS KANSAS IS EXPECTED TO
CONTINUE WORKING SOUTHEASTWARD AS THE MORNING PROGRESSES. SOME OF
THE ACTIVITY IS EXPECTED TO AFFECT PARTS OF NORTHWEST ARKANSAS BY
EARLY AFTERNOON...AND EVENTUALLY INTO CENTRAL SECTIONS OF THE STATE
AS THE AFTERNOON PROGRESSES.

.DAYS TWO THROUGH SEVEN...FRIDAY THROUGH WEDNESDAY

THE AFOREMENTIONED FRONT WILL GRADUALLY LIFT BACK NORTHWARD ACROSS
ARKANSAS FRIDAY AND FRIDAY NIGHT. ANY STORMS THAT DO DEVELOP ALONG
THE RETREATING FRONT ON FRIDAY WILL BE SPOTTY.

A RIDGE OF HIGH PRESSURE WILL BUILD OVER THE AREA FROM THE SOUTHWEST
OVER THE WEEKEND. TEMPERATURES WILL BE ABOVE NORMAL...WITH
AFTERNOON HEAT INDEX VALUES AROUND 100 DEGREES IN ALL BUT THE OZARK
MOUNTAINS OF THE NORTHWEST.

IT APPEARS THE HEAT WILL BE TEMPORARY. HIGH PRESSURE WILL WEAKEN
EARLY NEXT WEEK...AND THAT WILL ALLOW ANOTHER COLD FRONT TO DROP
SOUTHWARD THROUGH THE NATURAL STATE. COOLER CONDITIONS ARE EXPECTED
BEHIND THE FRONT.

.SPOTTER INFORMATION STATEMENT...

SPOTTER ACTIVATION IS NOT EXPECTED.
