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 (KSHV), launched 12:00Z, 9.6 hours before the alert went out and 153 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.

240 PM CDT WED JUN 3 2009

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

.DAY ONE...THIS AFTERNOON AND TONIGHT

A COLD FRONT WAS LOCATED ALONG A LINE FROM FORT SMITH TO SEARCY TO
SOUTH OF JONESBORO. THE FRONT WILL CONTINUE TO MOVE SLOWLY TO THE
SOUTH THIS AFTERNOON AND EVENING PRODUCING SHOWERS AND THUNDERSTORMS
ACROSS THE STATE.

CLEARING OCCURRED ACROSS MUCH OF THE SOUTHEAST HALF OF THE STATE
THIS MORNING. DAYTIME HEATING WAS HELPING TRIGGER STORMS THIS
AFTERNOON AND EVENING.

SOME OF THE STORMS HAVE AND MAY CONTINUE TO BECOME SEVERE. DAMAGING
WINDS AND PENNY SIZE HAIL OR LARGER ARE THE MAIN CONCERNS.

THERE IS ALSO ABUNDANT MOISTURE IN PLACE...WHICH WILL MAKE
DEVELOPING STORMS MORE EFFICIENT RAINMAKERS. GIVEN A SLOW STORM
MOVEMENT...HEAVY DOWNPOURS MAY LINGER IN SOME AREAS...AND THIS COULD
CAUSE LOCALIZED FLASH FLOODING.

.DAYS TWO THROUGH SEVEN...THURSDAY THROUGH TUESDAY

A CHANCE OF RAIN WILL CONTINUE THURSDAY MORNING...BEFORE THE FRONT
EXITS THE REGION TO THE SOUTH AND EAST. DRY AND COOLER WEATHER IS
EXPECTED ON FRIDAY. A WARMUP WILL OCCUR THIS WEEKEND AS A RIDGE OF
HIGH PRESSURE BUILDS OVER ARKANSAS. A COLD FRONT WILL TRY TO HEAD
TOWARD THE AREA EARLY NEXT WEEK...BUT WILL ENCOUNTER THE RIDGE AND
WILL SLOW DOWN.

ONLY SMALL CHANCES FOR SHOWERS AND THUNDERSTORMS ARE IN THE FORECAST
MONDAY AND TUESDAY...MAINLY IN NORTHERN SECTIONS OF THE STATE
NEAREST THE FRONT.

.SPOTTER INFORMATION STATEMENT...

SPOTTER ACTIVATION MAY IS NOT ANTICIPATED THIS AFTERNOON AND
EVENING...WITH SEVERE STORMS REMAINING ISOLATED.
