The local office's own words before this river flood warning went out, as it sent them, from the Iowa Environmental Mesonet's archive of National Weather Service text.

NWS Sioux Falls, SD wrote its last area forecast discussion before this river flood warning went out at May 27, 6:22 PM CDT, 2 hours 52 minutes earlier.

Area forecast discussion, May 27, 6:22 PM CDT, 2 hours 52 minutes before

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE SIOUX FALLS SD
622 PM CDT MON MAY 27 2013

.SHORT TERM...(THIS EVENING THROUGH TUESDAY)
ISSUED AT 341 PM CDT MON MAY 27 2013

SOUPY AIRMASS REMAINS ACROSS THE FORECAST AREA CREATING THE
POTENTIAL FOR ADDITIONAL HEAVY RAINFALL TONIGHT. AS OF 20Z...STORMS
BEGINNING TO DEVELOP IN WESTERN NEBRASKA INTO WESTERN SOUTH DAKOTA
AS SHORT WAVE MOVES INTO THE WESTERN HIGH PLAINS.  IN GENERAL...WAVE
IS EXPECTED TO MOVE FROM WEST TO EAST ACROSS SOUTH DAKOTA.  AT THE
SURFACE...WARM FRONT EXTENDING FROM NEAR VALENTINE NE DOWN TO NEAR
OMAHA.  AS WAVE WORKS EAST...THUNDERSTORMS ARE EXPECTED TO DEVELOP
IN THE VICINITY OF THE FRONT. TOUGH CALL ON CONVECTION TONIGHT WITH
CORFIDI VECTORS SUGGESTING A WEST TO EAST ORIENTATION....KEEPING THE
FOCUS OF THUNDERSTORMS MAINLY SOUTH OF THE FORECAST AREA.  MODELS
SUGGEST THAT A FAIRLY STRONG LOW LEVEL JET IS EXPECTED TO FEED INTO
THE BOUNDARY TONIGHT CREATING A GOOD OVER-RUNNING EVENT.  IF THE
STORMS BEGIN TO TURN MORE NORTHEAST TONIGHT...ATMOSPHERE IS PRIMED
FOR HEAVY RAIN.  PW VALUES RANGE FROM 1.3 TO 1.5 INCHES...WHICH IS
NEAR TWO STANDARD DEVIATIONS ABOVE NORMAL.  FORECAST SOUNDINGS
INDICATE TALL THIN CAPE WITH NEARLY SATURATED SOUNDING THROUGH THE
TROPOSPHERE.  SHEAR PROFILES ARE FAIRLY UNIDIRECTIONAL...SO OUTSIDE
OF SPEED SHEAR LEADING TO A VERY MARGINAL HAIL THREAT...AM MOST
CONCERNED ABOUT HEAVY RAIN AND FLOODING POTENTIAL FOR THE
OVERNIGHT.  HAVE BEEFED UP QPF ESPECIALLY ACROSS NORTHWEST
IOWA...AND MAINTAINED FLASH FLOOD WATCH THROUGH THE OVERNIGHT.

COMPLEX WILL MOVE OUT OF THE FORECAST AREA LEADING TO MAINLY DRY DAY
ACROSS THE AREA ON TUESDAY.  APPEARS TO BE LESS CLOUDS ACROSS THE
AREA ON TUESDAY...AND WITH WARM FRONT SLOWLY INCHING NORTH...AM
EXPECTING WARMER DAY ACROSS THE AREA.

.LONG TERM...(TUESDAY NIGHT THROUGH MONDAY)
ISSUED AT 341 PM CDT MON MAY 27 2013

MAIN UPPER LEVEL TROUGHING LIFTS INTO THE CENTRAL AND EASTERN HIGH
PLAINS ON WEDNESDAY...WITH A SURFACE LOW EXPECTED TO DEEPEN OVER
EASTERN COLORADO. PRECIPITATION REMAINS LIKELY FOR WEDNESDAY AND
WEDNESDAY NIGHT WITH INSTABILITY. SEVERE WEATHER STILL LOOKS LIKE A
POSSIBILITY THROUGHOUT THE FORECAST AREA...HOWEVER THE BIG QUESTION
WILL BE WHETHER THERE WILL BE ENOUGH SUNSHINE TO DESTABILIZE THINGS
AND BREAK THE EXPECTED CAPPING LAYER. COULD POTENTIALLY SEE CAPES OF
2000+ J/KG WITH MODEST SHEAR AND SOLID DYNAMIC SUPPORT. AS HAS BEEN
THE CASE OF LATE...HEAVY RAINFALL AND FLOODING WILL LIKELY CONTINUE
TO BE A LARGE CONCERN.

BY THURSDAY...THE TROUGH SWINGS NORTHWARD INTO THE NORTHERN PLAINS.
SHOWERS AND THUNDERSTORMS POTENTIAL WILL PERSIST THROUGH THE
DAY...HOWEVER WITH LOW AND MID LEVEL FLOW TURNING MORE
SOUTHWESTERLY...MOISTURE BECOMES A BIT MORE LIMITED AND THE
POTENTIAL FOR LOCALLY HEAVY RAINFALL FINALLY BEGINS TO DIMINISH.
WITH THE UPPER LEVEL FEATURE EXPECTED TO WOBBLE OVER THE NORTHERN
PLAINS INTO THE UPPER MISSISSIPPI VALLEY INTO FRIDAY
NIGHT...SCATTERED SHOWERS AND THUNDERSTORMS REMAIN IN THE PICTURE
BEFORE FINALLY DIMINISHING ON SATURDAY. MODELS CONTINUE TO SHOW
UNCERTAINTY LATE WEEK BUT IT DOES LOOK LIKE RIDGING IS EXPECTED TO
RETURN TO THE HIGH PLAINS BY SUNDAY WITH DRY CONDITIONS LIKELY
SATURDAY NIGHT THROUGH AT LEAST MONDAY.

.AVIATION...(FOR THE 00Z TAFS THROUGH 00Z TUESDAY EVENING)

TAF SITES HON/FSD/SUX ON THE EDGE OF MVFR/IFR STRATUS THIS
EVENING. STRATUS SHOULD EXPAND AND ADVECT EAST ACROSS THE REGION
THIS MID TO LATE EVENING. THUNDERSTORM COMPLEXES ARE EXPECTED TO
PUSH THROUGH THE REGION AGAIN TONIGHT MAINLY AFTER 05Z AND ENDING
BEFORE 12Z. SOME STORMS MAY BE STRONG AND REDUCED CONDITIONS TO
IFR AT TIMES. AREAS OF LOW STRATUS AND SOME HAZE/LIGHT FOG WILL
PERSIST THROUGH EARLY MORNING TUESDAY. VFR CONDITIONS ARE THEN
EXPECTED TO PREVAIL BY MID MORNING TUESDAY AND THROUGH THE DAY.

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

.DAY ONE...TODAY AND TONIGHT

THUNDERSTORMS...
ANOTHER ROUND OF SHOWERS AND THUNDERSTORMS IS EXPECTED TO PUSH IN
FROM OUR SOUTHWEST THIS EVENING INTO THE OVERNIGHT. THE HEAVIEST OF
THE ACTIVITY IS EXPECTED TO BE ACROSS NORTHWEST IOWA AND EXTREME
SOUTHEAST SOUTH DAKOTA. HAIL UP TO DIME SIZE AND WINDS GUSTING TO 50
MPH WILL BE THE MAIN THREATS WITH ANY STORMS THAT MOVE THROUGH THAT
REGION TONIGHT. ELSEWHERE...THUNDERSTORMS ARE STILL POSSIBLE...BUT
CURRENT THOUGHTS ARE THAT THESE WILL BE OF A LOWER INTENSITY.

FLOODING...
SEVERAL SMALL CREEKS AND STREAMS ACROSS EXTREME SOUTHEAST SOUTH
DAKOTA AND NORTHWEST IOWA LIKELY REMAIN IN FLOOD EARLY THIS
MORNING. ADDITIONAL HEAVY RAIN MAY OCCUR THIS EVENING INTO THE
OVERNIGHT AS THUNDERSTORMS MOVE BACK INTO THE AREA. THUS
ADDITIONAL FLASH FLOODING OF AREA CREEKS AND STREAMS IS POSSIBLE.

RIVER FLOODING IS ALSO OCCURRING OR FORECAST TO OCCUR ALONG
PORTIONS OF THE JAMES RIVER...VERMILLION RIVER...BIG SIOUX
IVER...FLOYD RIVER...OCHEYEDAN RIVER AND THE LITTLE SIOUX RIVER.
SEE ASSOCIATED FLOOD WARNINGS FOR MORE INFORMATION ON TIMING AND
EXPECTED CREST HEIGHTS.

.DAYS TWO THROUGH SEVEN...TUESDAY THROUGH SUNDAY

ANOTHER ROUND OF THUNDERSTORMS IS POSSIBLE TUESDAY NIGHT.
WIDESPREAD SEVERE WEATHER IS NOT EXPECTED...BUT AN ISOLATED
STRONGER STORM PRODUCING QUARTER SIZE HAIL IS POSSIBLE. FLASH
FLOODING WILL BE A THREAT AS WELL ACROSS SOUTHEAST SOUTH DAKOTA
AND NORTHWEST IOWA WHERE HEAVY RAIN HAS RECENTLY FALLEN.

WIDESPREAD THUNDERSTORMS ARE LIKELY WEDNESDAY AFTERNOON INTO
THE OVERNIGHT. THIS ROUND OF STORMS HAS A BETTER CHANCE OF
PRODUCING SEVERE WEATHER AND FLOODING.

MORE THUNDERSTORMS....A FEW OF WHICH MAY BE SEVERE...ARE LIKELY
THURSDAY AND THURSDAY NIGHT...CONTINUING THE FLOOD THREAT.

.SPOTTER INFORMATION STATEMENT...

SPOTTER ACTIVATION WILL NOT BE NEEDED TODAY AND TONIGHT.
