What was reported inside it

Time	Report	Where	Remark
Jun 1, 5:12 PM CDT	HAIL 0.88	10 Nw Ozark, AR	0.88 INCH HAIL REPORTED ALONG INTERSTATE 40 IN WESTERN FRANKLIN CO.

Local storm reports filed while the alert was in force, from inside its polygon or its counties.

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

Springfield, MO (KSGF), launched 12:00Z, 9.9 hours before the alert went out and 142 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.

241 PM CDT FRI JUN 1 2007

.DISCUSSION...
CU FIELD BUBBLING AVER SE OK THIS AFTERNOON...WHERE NE OK AND NW
HAVE BEEN STABILIZED AT LEAST FOR NOW BY MORNING CONVECTION. IT
APPEARS GRADIENT SURFACE FLOW HAS BEEN RESTORED TO MOST IF NOT ALL
OF THE AREA PER THE MESONET. SCATTERED STORMS THIS AFTERNOON
POSSIBLE JUST ABOUT ANYWHERE...HOWEVER THE UNTAPPED ENVIRONMENT OF
SE OK APPEARS TO BE A SLIGHTLY FAVORED AREA AT THIS TIME. PRIMARY
FOCUS FOR TONIGHT WILL BE ANOTHER COMPLEX THAT WILL DEVELOP TO THE
NORTH IN THE VICINITY OF THE SURFACE BOUNDARY AND TRACK SOUTHEAST.
ONCE AGAIN...NORTHEAST OKLAHOMA WILL SEE THE BEST CHANCES FOR
THUNDERSTORMS LATER TONIGHT AND TOMORROW MORNING. WHETHER IT IS
THE TRUE FRONT OR AN OUTFLOW BOUNDARY...STORM CHANCES WILL SLIDE
SOUTH ACROSS THE AREA WITH THE BOUNDARY. PLAN ON FOLLOWING CURRENT
TREND IN DECREASING POPS FROM NORTH TO SOUTH SATURDAY AFTERNOON
AND NIGHT...AND JUST TAPER TO SLIGHT CHANCE POPS ACROSS ALL OF THE
AREA FOR SUNDAY. DRIER AIR UNDER NORTHERLY SURFACE FLOW WILL BE
THE RULE FOR THE FIRST PART OF THE WEEK...THEN A WARMING TREND
COMMENCES FOR THE MID AND LATTER PARTS OF THE WORK WEEK.

THIS OUTLOOK IS FOR NORTHWEST AND WEST CENTRAL ARKANSAS AS WELL AS
MUCH OF EASTERN OKLAHOMA.

.DAY ONE...TODAY AND TONIGHT.

SEVERE THUNDERSTORM.
	RISK...LIMITED.
	AREA...EASTERN OKLAHOMA AND NORTHWEST ARKANSAS.
	ONSET...MID AFTERNOON.

FLASH FLOOD.
	RISK...LIMITED.
	AREA...NORTHWEST OF INTERSTATE 44.
	ONSET...MID AFTERNOON.

HEAVY RAIN.
	RISK...LIMITED.
	AREA...NORTHWEST OF INTERSTATE 44.
	ONSET...MID AFTERNOON.

DISCUSSION...
THE MCS THAT PUSHED THROUGH MUCH OF THE AREA BEFORE DISSIPATING
THIS MORNING HAS LEFT A BOUNDARY THAT RUNS FROM JUST SOUTH OF
FORT SMITH TO SOUTH OF MCALESTER. THIS BOUNDARY IS SLOWLY
MOVING NORTH. THE WARMEST TEMPERATURES...HIGHEST DEW POINTS AND THUS
GREATEST INSTABILITY IS SOUTH OF THIS BOUNDARY. HOWEVER THE
BEST CHANCES OF THUNDERSTORM DEVELOPMENT WILL BE ALONG AND
NORTH OF THE BOUNDARY AS TEMPERATURES CLIMB AND THE ATMOSPHERE CONTINUES
TO DESTABILIZE. THE SCATTERED THUNDERSTORMS WILL HAVE SOME POTENTIAL TO
BE SEVERE WITH STRONG OUTFLOW WINDS BEING THE MOST LIKELY THREAT.

SCATTERED SHOWERS AND THUNDERSTORMS WILL CONTINUE THROUGH THE EVENING
AND OVERNIGHT AS A COLD FRONT APPROACHES FROM THE NORTH THERE IS
A RISK OF VERY HEAVY RAIN WITH SOME OF THE THUNDERSTORMS ASSOCIATED
WITH THE APPROACHING FRONT AND AMOUNTS OF 3/4 TO 1 AND 1/2 INCHES
ARE EXPECTED IN THE AREA NORTHWEST OF INTERSTATE 44. SINCE MOST
OF THIS RAIN WOULD FALL IN A SHORT PERIOD OF TIME...THIS COULD CAUSE
LOCALIZED FLOODING DUE TO THE RAIN THAT FELL FROM LAST NIGHT
STORMS.

SPOTTER AND EMERGENCY MANAGEMENT ACTION STATEMENT...
SPOTTER ACTIVATION MAY BE NEEDED LATE THIS AFTERNOON OR TONIGHT.

.DAYS TWO THROUGH SEVEN...SATURDAY THROUGH THURSDAY.
SATURDAY...THUNDERSTORM POTENTIAL.
SUNDAY...THUNDERSTORM POTENTIAL.
MONDAY...NO HAZARDS.
TUESDAY...NO HAZARDS.
WEDNESDAY...NO HAZARDS.
THURSDAY...NO HAZARDS.

EXTENDED DISCUSSION...
SHOWERS AND THUNDERSTORMS WILL REMAIN IN THE FORECAST OVER THE
WEEKEND DUE TO THE MOIST AND UNSTABLE AIR MASS OVER THE AREA
ALONG WITH THE COLD FRONT THAT IS FORECAST TO BECOME NEARLY
STATIONARY ACROSS THE REGION AND SLOWLY WASHING OUT. UPPER
LEVEL SUPPORT REMAINS WEAK AND WILL LIMIT POTENTIAL FOR
ORGANIZED SEVERE WEATHER.
