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.

Area forecast discussion, Jun 21, 11:28 AM CDT, 12 minutes before

AREA FORECAST DISCUSSION FOR SOUTHEAST SD/SOUTHWEST MN/NORTHWEST IA
NATIONAL WEATHER SERVICE SIOUX FALLS SD
1128 AM CDT TUE JUN 21 2011

.DISCUSSION...
WATER VAPOR LOOP PRESENTLY SHOWING THE UPPER LEVEL LOW SWIRLING OVER
OUR AREA. THE HEAVIER RAIN CONTINUES TO OCCUR THROUGH CENTRAL SOUTH
DAKOTA IN ASSOCIATION WITH MIDLEVEL TROWAL/INVERTED SURFACE
TROUGH...WITH MORE SCATTERED TYPE SHOWERS BACK TO THE EAST.
ANTICIPATE THE MORE STEADY RAIN TO SLOWLY TRANSITION EASTWARD
THROUGH THE DAY AND INTO THIS EVENING AS THE SYSTEM TRACKS INTO THE
UPPER MIDWEST. ELECTED TO GO AHEAD AND CANCEL THE FLASH FLOOD WATCH
WITH ONLY VERY ISOLATED THUNDERSTORMS EXPECTED IN AN ONLY WEAKLY
UNSTABLE REGIME...AND ADDITIONAL DAYTIME RAINFALL AMOUNTS
ANTICIPATED TO REMAIN LESS THAN HALF AN INCH. ALSO...WITH THE OTHER
NUMEROUS HYDROLOGICAL WARNINGS ALREADY ISSUED...A WATCH MAY BE
CONFUSING TO USERS AND LESS PERTINENT. UPDATES OUT.  /JM

&&

.PREV DISCUSSION...
POTENT UPPER LOW PRESSURE SYSTEM HAS DRIFTED EASTWARD ALONG THE
KANSAS AND NEBRASKA BORDER THIS MORNING.  LARGE SWATH OF SHOWERS AND
THUNDERSTORMS WHICH DROPPED 2 INCHES OR MORE OF RAINFALL ACROSS MUCH
OF THE FORECAST AREA HAS MOVED OUTSIDE OF OUR BORDERS.  SECONDARY
BAND OF SHOWERS ROTATING AROUND THE LOW CENTER HAS BEGUN TO SPREAD
NORTH-NORTHEASTWARD INTO OUR SOUTHERN BORDER. MODELS SUGGEST THAT
THE INVERTED TROUGH ASSOCIATED WITH THIS LOW WILL CONTINUE TO PUSH
SLOW MOVING BANDS OF SHOWERS ACROSS THE FORECAST AREA THROUGH THIS
AFTERNOON...WITH THE LOW CENTER DRIFTING NORTHWARD OVER THE EASTERN
COUNTY WARNING AREA BEFORE TURNING MORE EASTERLY INTO THE UPPER
MISSISSIPPI VALLEY BY WEDNESDAY AFTERNOON.

DEEP MOISTURE POOL SUGGESTS THAT LOCALLY HEAVY RAINFALL WILL
CONTINUE TO BE A THREAT TODAY...ESPECIALLY ACROSS THE NORTHERN
HALF...WHICH WILL SEE THE MOST PROLONGED RAINFALL AS THE INVERTED
TROUGH AXIS SHIFTS NORTHWARD TODAY.  FLASH FLOOD WATCH REMAINS IN
EFFECT THROUGH THIS EVENING FOR SOUTHEAST SD...NORTHWEST MN AND
EXTREME NW IA. GIVEN THE LARGE AMOUNT OF RAIN THAT FELL LAST
EVENING/THIS MORNING...THE GROUND REMAINS QUITE SATURATED. AREAL
FLOOD WARNING REMAINS ACROSS THE FAR WESTERN CWA WHERE AS MUCH AS 8
INCHES OF RAINFALL HAS CAUSED AREA STREAMS AND RIVERS TO SPIKE UP
SIGNIFICANTLY.  EXPECT ADDITIONAL RAINFALL THIS AFTERNOON TO KEEP
THESE RIVERS AND STREAMS ELEVATED...SO WILL LIKELY SEE THIS WARNING
EXTENDED LATER THIS MORNING.

WET WEATHER CONTINUES INTO WEDNESDAY...HOWEVER RAINFALL RATES ARE
EXPECTED TO WANE TONIGHT AND WEDNESDAY WITH THE LOW CENTER MOVING
OVERHEAD AND THE BEST FORCING MOVING NORTH OF OUR CWA. THE WESTERN
CWA SHOULD BEGIN DRYING OUT ON WEDNESDAY WITH A VERY GRADUAL
DECREASE IN PRECIPITATION CHANCES FROM WEST TO EAST WEDNESDAY NIGHT
AND THURSDAY. BELOW NORMAL TEMPERATURES WILL PERSIST IN THE
NORTHWEST FLOW BEHIND THE LOW. DRY WEATHER FINALLY ENCOMPASSES THE
CWA ON THURSDAY AS RIDGING BEGINS BUILDING OVER THE HIGH PLAINS.
MODELS DO SUGGEST THAT A WEAK WAVE RIDING OVER THE RIDGE COULD BRING
SOME UNSETTLED WEATHER INTO THE MID MISSOURI VALLEY LATE WEEK.
CONTINUED WITH SOME LOW CHANCE POPS LATE WEEK.  TEMPERATURES WILL
OVERALL REMAIN BELOW NORMAL.

&&

.AVIATION...
A STRONG AREA OF LOW PRESSURE OVER EASTERN NEBRASKA WILL LIFT NORTH
TODAY INTO WESTERN MINNESOTA.  AS IT DOES SO...LOW CLOUDS AROUND
1000 FEET AGL AND SCATTERED SHOWERS WILL SHIFT FROM WEST TO EAST
ACROSS THE REGION. SHOWERS WILL BE MOST WIDESPREAD ALONG THE JAMES
RIVER TODAY...SHIFTING EAST TOWARDS THE I-29 CORRIDOR TOWARDS 00Z
WED.  EASTERLY WINDS WILL TRANSITION TO NORTHERLY AS THE THE
INVERTED TROUGH ACROSS CENTRAL SOUTH DAKOTA SLOWLY SHIFTS EAST.

&&

.FSD WATCHES/WARNINGS/ADVISORIES...
IA...NONE.
MN...NONE.
NE...NONE.
SD...NONE.
