Did it verify

Verified. The Iowa Environmental Mesonet's Cow matched one storm report to this flash flood warning; the first came 43 minutes after it went out.

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, May 26, 3:02 PM CDT, 5 hours 27 minutes before

AREA FORECAST DISCUSSION...CORRECTED
NATIONAL WEATHER SERVICE MEMPHIS TN
302 PM CDT FRI MAY 26 2006

.DISCUSSION...

ANOTHER HOT AND HUMID AFTERNOON ACROSS THE MID SOUTH WITH
TEMPERATURES BACK INTO THE UPPER 80S TO LOWER 90S ALONG WITH
DEWPOINTS IN THE LOWER 70S. A HEALTHY CU FIELD HAS DEVELOPED IN
RESPONSE TO DAYTIME HEATING AND ISOLATED THUNDERSTORMS WILL BE
POSSIBLE AS DAYTIME HEATING CONTINUES...INSTABILITY BECOMES
MAXIMIZED WITH MLCAPES 3500-4500J/KG...AND A MESOSCALE CONVECTIVE
VORTEX (MCV) MOVING ACROSS NORTHERN ARKANSAS ATTEMPTS TO INITIATE
CONVECTIVE DEVELOPMENT OVER NORTHWEST SECTIONS. THIS WARRENTS SLIGHT
CHANCE POPS AREAWIDE FOR THE REMAINDER OF THIS AFTERNOON AND
EVENING. THE MAGNITUDE OF THE INSTABILITY SHOULD SUPPORT PULSE
SEVERE THUNDERSTORMS THAT MAY PRODUCE DAMAGING WINDS AND LARGE HAIL.
WILL CONTINUE SLIGHT RISK FOR PULSE SEVERE THROUGH THIS EVENING.
PLAN AT THIS POINT TO DROP POPS AFTER 03Z WITH LOSS OF DIURNAL
INSTABILITY AND WEAKENING TRIGGERING MECHANISM LATER TONIGHT.
APPEARS THAT GFS MCS DEVELOPMENT IS WAY OVERDONE AND PREFER NAM DRY
TRENDS FOR LATER TONIGHT.

UPPER LEVEL RIDGE AXIS SHOULD SLIDE EAST ON SATURDAY. INCREASED
SUBSIDENCE WITH UPPER RIDGE COMBINED WITH LACK OF A GOOD FORCING
MECHANISM SHOULD KEEP MOST AREAS DRY. HOT AND HUMID WEATHER WILL
PERSIST AS WE CONTINUE IN A MORE SUMMERLIKE WEATHER PATTERN.
CANNOT COMPLETELY RULE OUT AN ISOLATED THUNDERSTORM DURING PEAK
HEATING AND MAXIMUM INSTABILITY...BUT OVERALL COVERAGE SHOULD BE
LOW ENOUGH TO KEEP OUT OF THE FORECAST.

THE UPPER LEVEL RIDGE WILL CONTINUE TO SLIDE EAST THROUGH THE
REMAINDER OF THE WEEKEND AND BE POSITIONED TO OUR EAST FOR SUNDAY
INTO THE FIRST HALF OF NEXT WEEK. THE MEDIUM RANGE GUIDANCE IS NOW
MORE BULLISH (INCLUDING THE GFS AND ECMWF) WITH BRINGING UP
INCREASED MOISTURE FROM THE GULF OF MEXICO DURING THE SUNDAY
THROUGH WEDNESDAY TIME PERIOD. ALSO WEAK UPPER LEVEL SHORTWAVE
DISTURBANCES WILL TRAVERSE OVER THE AREA THROUGH THIS PERIOD ALONG
THE WESTERN PERIPHERY OF THE RIDGE AND EAST OF A DEVELOPING FULL
LATITUDE WESTERN TROUGH. THIS WILL BRING A RETURN TO DAILY CHANCES
FOR SCATTERED SHOWERS AND THUNDERSTORMS ACROSS THE REGION. THE
BEST CHANCES WILL REMAIN DIURNALLY DRIVEN BUT CANNOT RULE OUT
SLIGHT SHOWER AND THUNDERSTORM CHANCES OVERNIGHT AS WELL WITH WEAK
SHORTWAVES ALOFT. THE INCREASED PRECIPITATION AND CLOUD COVER FOR
SUNDAY THROUGH WEDNESDAY WILL HOLD TEMPERATURES DOWN A BIT FROM
THIS WEEKENDS HIGHS. BUT STILL EXPECTING HIGHS AROUND 90 AND LOWS
IN THE UPPER 60S TO LOWER 70S WITH CONTINUED HIGH HUMIDITY LEVELS.
EVEN WITH INCREASED MOISTURE DURING THIS PERIOD...HAVE DECIDED TO
UNDERCUT MEX POPS...WITH NO STRONG UPPER LEVEL SUPPORT FOR
WIDESPREAD PRECIPITATION. ALSO AS A RESULT OF LESS PRECIP...HAVE
RAISED EXTENDED TEMPERATURES ABOVE MEX GUIDANCE...ESPECIALLY FOR
DAYTIME HIGHS.

BY WEDNESDAY NIGHT...A DAMPENING BUT STRONGER NORTHERN STREAM
SHORTWAVE WILL ATTEMPT TO PUSH A COLD FRONT ACROSS THE AREA
THROUGH THURSDAY NIGHT. FOR NOW HAVE GONE WITH FRONTAL PASSAGE AND
SCATTERED SHOWERS AND THUNDERSTORMS WITH THE FRONT. WILL NEED TO
KEEP AN EYE ON THIS SYSTEM TO MAKE SURE IT MAKES IT THROUGH THE
AREA. FOR NOW HAVE GONE WITH DRY AND SLIGHTLY COOLER WEATHER FOR
NEXT FRIDAY...BUT MAY NEED TO ADJUST THIS FORECAST IF FRONT STALLS
OUT OVER OUR AREA. PLENTY OF TIME THOUGH TO KEEP AN EYE ON THIS
SCENARIO AS IT IS STILL FAR INTO THE EXTENDED PERIOD.

THIS HAZARDOUS WEATHER OUTLOOK IS FOR PORTIONS OF EAST ARKANSAS...
THE MISSOURI BOOTHEEL...NORTH MISSISSIPPI...AND WEST TENNESSEE.

.DAY ONE...THIS AFTERNOON AND TONIGHT

THERE IS A SLIGHT RISK FOR SEVERE THUNDERSTORMS ACROSS THE MID
SOUTH THIS AFTERNOON AND EVENING. AN UPPER LEVEL DISTURBANCE WILL
INTERACT WITH INCREASINGLY UNSTABLE CONDITIONS TO ALLOW FOR THE
DEVELOPMENT OF A FEW SEVERE THUNDERSTORMS. ANY THUNDERSTORMS THAT
DEVELOP WILL HAVE THE POTENTIAL TO PRODUCE DAMAGING WINDS AND
LARGE HAIL.

.DAYS TWO THROUGH SEVEN...SATURDAY THROUGH THURSDAY

SUFFICIENT MOISTURE AND INSTABILITY WILL ALLOW FOR DAILY CHANCES
OF ISOLATED TO SCATTERED AFTERNOON THUNDERSTORMS OVER THE NEXT
SEVERAL DAYS. GIVEN THE DEGREE OF INSTABILITY EXPECTED...A FEW OF
THESE THUNDERSTORMS MAY BE STRONG WITH GUSTY WINDS AND HAIL
POSSIBLE.

.SPOTTER INFORMATION STATEMENT...

ACTIVATION OF STORM SPOTTERS...EMERGENCY MANAGEMENT...AND LAW
ENFORCEMENT OFFICIALS MAY BE NEEDED THIS AFTERNOON AND EVENING.
