THIS HAZARDOUS WEATHER OUTLOOK IS FOR SOUTHEAST SOUTH DAKOTA...
SOUTHWEST MINNESOTA...NORTHWEST IOWA...AND NORTHEAST NEBRASKA.

.DAY ONE...TODAY AND TONIGHT

THUNDERSTORMS...
THUNDERSTORMS WILL DEVELOP EARLY THIS EVENING ACROSS THE
MISSOURI RIVER CORRIDOR. AN ISOLATED STORM WILL BE CAPABLE OF
LARGE HAIL TO HALF DOLLAR SIZE AND DAMAGING WINDS TO 60 MPH THIS
EVENING THROUGH SHORTLY AFTER MIDNIGHT AS THEY DRIFT TO THE EAST
AND NORTHEAST...MAINLY SOUTH OF A CHAMBERLAIN TO CANTON TO STORM
LAKE LINE.  ANOTHER LARGE COMPLEX OF THUNDERSTORMS IS LIKELY TO
ORGANIZE WEST OF THE AREA DURING THE EVENING...AND BUILD
SOUTHEAST THROUGH EASTERN SOUTH DAKOTA AND SOUTHWEST MINNESOTA BY
LATE NIGHT. THE SEVERE WEATHER THREAT WITH THESE STORMS APPEARS
TO BE SMALL...BUT WIND GUSTS OF 40 TO 50 MPH AND HAIL UP TO THE
SIZE OF QUARTERS WILL BE POSSIBLE WITH STORMS.	SOME AREAS OF
HEAVY RAINFALL WILL BE POSSIBLE WITH THE POTENTIAL TO CAUSE
PONDING IN POOR DRAINAGE AREAS.

.DAYS TWO THROUGH SEVEN...SUNDAY THROUGH FRIDAY

ADDITIONAL THUNDERSTORMS ARE POSSIBLE AGAIN LATE SUNDAY AFTERNOON
AND SUNDAY NIGHT...CREATING THE POTENTIAL FOR HEAVY RAIN AND
FLASH FLOODING. MAINLY SOUTH OF INTERSTATE 90. A FEW STORMS MAY
ALSO BE SEVERE WITH LARGE HAIL AND DAMAGING WINDS.  ANOTHER ROUND
OF THUNDERSTORMS IS EXPECTED BY MEMORIAL DAY LATE AFTERNOON AND
EVENING...AND AGAIN WILL BRING A THREAT FOR A SEVERE STORM.

THE UNSETTLED PATTERN WILL CONTINUE THROUGH MUCH OF THE UPCOMING
WEEK WITH PERIODIC CHANCES FOR THUNDERSTORMS THROUGH FRIDAY. IT
IS LIKELY THAT SEVERE STORMS WILL OCCUR AT TIMES AROUND THE
AREA...FOCUSING MAINLY DURING LATE DAY AND EVENING HOURS. THE
RISK FOR FLASH FLOODING WILL BE MODERATE TO HIGH...GIVEN THE
POTENTIAL FOR SEVERAL ROUNDS OF RAINFALL. HOWEVER...FOR EACH OF
THE FLOODING AND SEVERE WEATHER THREATS...IT IS DIFFICULT TO
LOCATE WHERE THE GREATEST RISK IS AT THIS TIME.

.SPOTTER INFORMATION STATEMENT...

SPOTTER ACTIVATION WILL BE POSSIBLE AFTER 7 PM CDT THROUGH THE 
MISSOURI RIVER CORRIDOR.
