What happened

The episode as NWS DMX wrote it up.

Heavy rainfall during the month of June caused considerable crop losses across the state. Crop damage was done through a combination of inundation flooding and losses due to crops not being able to be planted or rotting in the ground. It is not possible to get a clear breakdown of the percent of damage that can be attributed to each cause. The damage here is not related to the river flooding. Those flooding events are addressed in other flooding entries. Many of the southern Iowa counties were unable to plant crops at all through June, while areas of the central and north lost the crops that were planted through drowning or washouts. Estimates from the state and county extension offices indicated that about 10% of the crop was lost across the state. The amount of loss in the DMX CWA was around $1 billion to the corn and soybean crop. By the end of the month, Iowa Governor Culver declared 32 counties state disaster areas. They were Black Hawk, Buena Vista, Butler, Cherokee, Clay, Davis, Decatur, Emmet, Franklin, Hamilton, Hancock, Howard, Humboldt, Jasper, Jefferson, Kossuth, Lee, Lyon, Mahaska, Madison, Marion, Monroe, O'Brien, Osceola, Palo Alto, Polk, Ringgold, Sioux, Shelby, Taylor, Union, Van Buren, Wapello, Warren, Webster, Wright. An application for about 35 counties was made for a Presidential Disaster Declaration.

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE DES MOINES IA
1255 PM CDT SAT JUN 12 2010

...UPDATED FOR 18Z AVIATION DISCUSSION...

.SHORT TERM /TODAY/...
FOR THE THIRD MORNING IN A ROW...A LARGE CONVECTIVE SYSTEM WILL MOVE
FROM NEBRASKA IN IOWA PRODUCING VERY HEAVY RAINFALL.  IN
ADDITION...A QUASI STATIONARY BOUNDARY NEAR THE HIGHWAY 34 CORRIDOR
WILL BE A FOCUS FOR CONVECTION DURING THE MORNING.  SHEAR IS
RELATIVELY WEAK ACRS THE STATE WITH 500MB WINDS OF 5 TO 10 KTS...SO
SEVERE WEATHER APPEARS RELATIVELY MINIMAL.  HOWEVER...AMPLE MOISTURE
IS IN PLACE ALONG WITH DEEP WARM CLOUD LAYERS AND WARM PCPN
PROCESSES LEADING TO EFFICIENT RAIN PRODUCERS.  ONGOING FFA WILL BE
KEPT IN TACT AS LARGE CONVECTIVE COMPLEX MOVES INTO THE STATE.
GRIDS HAVE LIKELY TO CATEGORICAL POPS THROUGH THE MORNING FOR THIS
ONGOING CONVECTION WITH SCATTERED WORDING THIS AFTERNOON AS
EVOLUTION OF THE SYSTEM AND SUBSEQUENT CONVECTION REMAINS MURKY.
TEMPS ALSO PROBLEMATIC GIVEN CLOUDS AND RAINFALL DURING THE DAY SO
WL STICK CLOSE TO GUIDANCE.

.LONG TERM /TONIGHT THROUGH FRIDAY/...
MODELS OF LITTLE HELP FOR THE NEXT FEW DAYS AS MESOSCALE DOMINATES
CURRENT WX REGIME. SUBJECTIVE SFC ANALYSIS AT 06Z SHOWS BOUNDARY
FROM NEAR KOMA TO JUST SOUTH OF KDSM TO NEAR KDBQ. WEAK SFC LOWS
CONTINUE TO TRACK ALONG IT. VERY WARM AND HUMID ALONG THE BOUNDARY
AND MUCH COOLER AND DRIER NORTH. A SECONDARY COOL FRONT LIES ALONG
THE MN DAKOTAS BORDER AND NOW CATCHING UP WITH THE TROUGH THAT LIES
ACROSS THE PLAINS NOW.  UPPER LEVEL PATTERN SUGGESTS THAT THREAT FOR
MODERATE TO HEAVY RAINFALL WILL CONTINUE IN PART THROUGH MID TO END
OF WEEK...WITH DETAILS OF HOW MESOSCALE MODULATES THE FLOW A DAILY
GRIND FOR NOW.  H700 SHOWS 3 DISTINCT WAVES WHICH WILL AFFECT THE
REGION AGAIN TNT THROUGH MONDAY. MODELS DO HINT AT COOLER AND DRIER
AIR MASS TO ARRIVE ON TUESDAY FOR ABOUT 24 TO 30 HOURS BEFORE
ANOTHER WAVE PULLS SOUTHERN AIR MASS AND POTENTIAL MCS BACK ACROSS
THE AREA AGAIN FOR WED NIGHT AND THURSDAY. WITH SUBTROPICAL HIGH
ANCHORED OVER THE SOUTHEAST FOR MUCH OF THE WEEK...LITTLE CHANGE IN
PRECIP POTENTIAL EXPECTED. GEM IS A BIT MORE AGGRESSIVE WITH TAKING
THE LATE WEEK SYSTEM FARTHER NORTH. IN THE SHORTER TERM...WITH H850
MOISTURE LEVELS OF +20C DEWPOINTS FROM CENTRAL KS SOUTH TO WESTERN
TX AND LARGE AREA OF +15C DEW POINTS COVERING MOST OF THE EAST US...
A LOT OF WET WX TO COME. GENERAL FEELING IS THAT ONCE THIS DUAL MCS
WORKS ITS WAY EAST BY TONIGHT...THE SFC BOUNDARY WILL GRADUALLY
SHIFT SOUTH FOR SUNDAY AND INTO MONDAY...KEEPING HIGHER POPS ACROSS
THE SOUTH AT THAT TIME.  ANOTHER WAVE APPROACHES ON MONDAY NIGHT AND
EARLY TUESDAY AND HAVE BUMPED POP UP ONCE AGAIN. TEMPS WARM THE NEXT
2 DAYS AND THEN HAVE LOWERED HIGHS A BIT MOVING FORWARD.

&&

.AVIATION...
12/18...MORNING CONVECTION HAD PUSHED EAST BY 18Z...LEAVING MOST
SITES IN VFR CONDITIONS. EXPECT KMCW TO BOUNCE IN AND OUT OF IFR
CONDITIONS THROUGH AT LEAST 20Z AS LOW CLOUDS FORM ALONG A WEAK
BOUNDARY NEAR THE SITE. SIMILARLY...KOTM WILL SEE OCCASIONAL MVFR
CONDITIONS THROUGH 20Z AS LOWER CEILINGS STREAM IN FROM ONGOING
CONVECTION IN MISSOURI. EXPECT DEVELOPMENT OF ANOTHER MCS FOR THE
OVERNIGHT HOURS. SYSTEM SHOULD REMAIN MOSTLY TO THE SOUTH...THROUGH
KANSAS AND MISSOURI. HOWEVER...RAIN AND LOW CEILINGS ARE PROBABLE AT
ALL SITES...ESPECIALLY AFTER 06Z. THEREFORE...HAVE BROUGHT
VISIBILITIES DOWN FOR A SHORT TIME IN EARLY MORNING HOURS. TIMING
AND INTENSITY WILL NEED TO BE REEVALUATED WITH LATER UPDATES.

THIS HAZARDOUS WEATHER OUTLOOK IS FOR PORTIONS OF CENTRAL IOWA.

.DAY ONE...THIS AFTERNOON AND TONIGHT

SCATTERED THUNDERSTORM DEVELOPMENT IS POSSIBLE ACROSS THE AREA IN
THE AFTERNOON. THESE STORMS ARE NOT EXPECTED TO BECOME
SEVERE. A LARGER AREA OF THUNDERSTORMS AND HEAVY RAIN IS EXPECTED
TO MOVE IN TO THE REGION LATE TONIGHT. DAMAGING WINDS AND SMALL
HAIL ALONG WITH LOCALLY HEAVY RAINFALL AMOUNTS ARE THE MAIN THREATS.

.DAYS TWO THROUGH SEVEN...SUNDAY THROUGH FRIDAY

THUNDERSTORMS AND HEAVY RAIN ARE LIKELY EARLY SUNDAY. THE THREAT
OF SEVERE WEATHER IS LOW...HOWEVER LOCALLY HEAVY RAINFALL COULD
LEAD TO FLOODING.

THUNDERSTORM CHANCES CONTINUE INTERMITTENTLY THROUGHOUT THE
WEEKEND AND INTO NEXT WEEK. THERE THREAT OF SEVERE WEATHER APPEARS
FAIRLY MINIMAL AT THIS TIME FOR THE WEEKEND...AND IT IS TOO EARLY
TO DETERMINE THE CHANCE OF SEVERE WEATHER FOR NEXT WEEK. HEAVY
RAINFALL MAY ALSO OCCUR FROM TIME TO TIME THROUGH THE WEEK. AREA
RIVERS AND STREAMS WILL BE ON THE RISE DUE TO THE PERIODS OF
RAINFALL EXPECTED THIS WEEK.

.SPOTTER INFORMATION STATEMENT...

SPOTTER ACTIVATION IS NOT LIKELY TODAY...BUT RAINFALL REPORTS
