.DAY ONE...TODAY AND TONIGHT

THUNDERSTORMS...
OCCASIONAL SHOWERS AND ISOLATED THUNDERSTORMS WILL CONTINUE TO
MOVE NORTHWARD THIS AFTERNOON...MOST PREVALENT FOR AREAS ALONG
THE I 29 CORRIDOR AND POINTS EASTWARD. BECAUSE OF THE RAIN AND
CLOUD COVER...CONDITIONS HAVE STABILIZED FOR THESE AREAS. BUT IF
HEATING CAN TAKE PLACE BY THE MID AFTERNOON HOURS...A SEVERE
WEATHER THREAT WILL CERTAINLY EXIST MAINLY ALONG AND EAST OF A
SIOUX CITY IOWA TO MARSHALL MINNESOTA LINE. CONDITIONALLY IF THIS
HAPPENS...A LINE OF STORMS WILL LIKELY QUICKLY FORM...THEN MOVE
EASTWARD DURING THE EVENING HOURS. THE PRIMARY THREAT WILL
THEREFORE BE LARGE HAIL OF UP TO A HALF DOLLAR SIZE AND WINDS OF
60 TO 70 MPH IN THE SEVERE CELLS...MAINLY IN THE 4 PM TO 8 PM
TIME FRAME.

FLOODING...
AREAS OF HEAVY RAINFALL LATE THIS AFTERNOON AND EARLY THIS
EVENING COULD LEAD TO A SPOTTY FLASH FLOODING THREAT FOR
NORTHWEST IOWA AND PORTIONS OF SOUTHWEST MINNESOTA NEAR AND EAST

TUESDAY. HOWEVER...THE ENVIRONMENT ON TUESDAY APPEARS TO BE
FAVORABLE FOR DEVELOPMENT OF QUICK TORNADIC SPIN UPS DURING THE
DEVELOPING PHASE OF SHOWERS AND THUNDERSTORMS ALONG AND EAST OF
INTERSTATE 29. THE MOST LIKELY TIME FOR ANY TORNADIC DEVELOPMENT
WILL BE FROM NOON TO 4 PM AS A AREA OF SHOWERS AND THUNDERSTORMS
IS EXPECTED TO BECOME MORE PREVALENT.

AFTER THE EARLY DAY STORMS...MUCH OF THE DAY IS EXPECTED TO
REMAIN QUIET...UNTIL A SMALL CHANCE FOR THUNDERSTORMS WEST OF THE
JAMES VALLEY STARTS LATE THIS AFTERNOON. THE CHANCE FOR
THUNDERSTORMS WILL INCREASE DURING THE EVENING FROM THE JAMES

THREAT BY MID AFTERNOON AND THROUGH THE EVENING HOURS ON
SUNDAY...THERE IS A MUCH GREATER PROBABILITY FOR LOCATIONS EAST
OF THE JAMES RIVER...AND ESPECIALLY FOR AREAS EAST OF YANKTON TO
SIOUX FALLS LINE. LARGE HAIL UP TO 2 INCHES IN DIAMETER...ALONG
WITH A SMALL THREAT FOR AN ISOLATED TORNADO WILL EXIST FROM THE
LOWER MISSOURI VALLEY THROUGH NORTHWEST IOWA. DAMAGING WINDS OF
60 TO 80 MPH WILL ALSO INCREASE IN LIKELIHOOD BY THE EVENING
HOURS AS STORMS SPREAD EAST THROUGH NORTHWEST IOWA. A LOWER END
LARGE HAIL AND WIND THREAT WILL EXIST NORTH OF INTERSTATE 90.
