The episode as NWS DMX wrote it up.
Water continued to flow at above normal levels through the Des Moines River system. In addition, another round of heavy rainfall moved through Iowa, especially the water soaked southern half. Flooding took place on several streams across the south. The flooding was minor with damage limited to agricultural areas for the most part.

DOUBLE MCS/S MOVING THRU SD AND NEB ARE SHIFTING SWD THIS MRNG AS COMPLEX OVR SRN NEBRASKA TAKES OVER ON THE NOSE OF THE LLJ AND MOISTURE INFLOW. EXPECT TO SEE THIS CONTINUE TO DEVELOP EWD ALONG THE SHEAR AXIS PRESENT FROM SRN NEBRASKA INTO NRN MO AS LLJ VEERS TWD SNRS. STRONGEST STORMS LIKELY TO REMAIN SOUTH OF THE CWA...BUT EXPECT TO SEE A LARGE AREA OF MOD TO OCNLY HEAVY RAFL THIS MRNG OVR THE SWWN THIRD TO HALF OF THE CWA. WILL CONT THE MNTN OF LOCALLY +RA FOR THIS AREA AS WELL. TSRA WILL WEAKEN LATER THIS MRNG AND AFFECT MAINLY THE SERN ZNS. WOULD SEE SCT DVLPT ABOUT ANYWHERE THIS AFTN...BUT NOT LOOKING FOR AN ORGANIZED SYSTEM. TEMPS ARE TRICKY WITH THE CLOUDS AND RAIN. LOWERED MAX TEMPS...ESPECIALLY ACRS THE SOUTH...DUE TO CLOUDS AND LIKELIHOOD THAT MOST OF THE DAY WILL HAVE AT LAST SCT-BKN AREA OF TSRA OVR IT. .LONG TERM /TONIGHT THROUGH FRIDAY/... BEGINNING OF PERIOD VERY TRICKY WITH LIKELY DEVELOPMENT OF YET ANOTHER MCS ACROSS CENTRAL NE...WITH TRACK EASTWARD DIFFICULT TO DETERMINE. COULD SEE MCS INTO CENTRAL IOWA BEFORE PULLING SOUTH. HOWEVER...FEEL MOST LIKELY SCENARIO WILL SEE MCS TRACK NEAR LLJ WHICH WILL BE FURTHER SOUTH INTO KS/MO. HAVE INCLUDED CHANCE POPS THROUGHOUT OVERNIGHT...WITH LIKELY ALONG SOUTH. WITH ADDITIONAL MOISTURE IN OVERNIGHT...WILL LIKELY SEE FOG ACROSS THE REGION...WITH DENSE FOG POSSIBLE IN SPOTS. LATE SUNDAY A FRONT ASSOCIATED WITH LOW PRESSURE IN SOUTHERN KS WILL LIFT NORTHWARD ACROSS IOWA. THIS WILL LIKELY BE FOCUS FOR STORM DEVELOPMENT. COULD SEE SOME STRONG TO SEVERE STORMS OVERNIGHT...WITH STRONG SHEAR AND CAPES OVER 1000 J/KG...HOWEVER APPEARS MOST LIKELY THREAT WILL BE HEAVY RAIN. SYSTEM WILL PULL AWAY BY LATE MONDAY. COULD AGAIN SEE POTENTIAL FOR STRONG STORMS LATE MONDAY...HOWEVER...MODELS ARE BECOMING MORE PROGRESSIVE WITH FRONT...TRYING TO SWEEP IT CLEAR OF IOWA WITH SEVERE POTENTIAL FOCUSED ALONG BOUNDARY. WILL HAVE TO KEEP A CLOSE EYE ON THIS SYSTEM. HIGH PRESSURE WILL THEN BUILD IN BENEATH UPPER LEVEL RIDGE FOR MOST OF REMAINDER OF THE PERIOD. ANOTHER QUICK SHOT FOR SOME PRECIPITATION WEDNESDAY WITH APPROACHING WAA. AS RIDGE BUILD...THIS WILL LEAD TO HOT AND MUGGY CONDITIONS FOR THE WEEKEND WITH H850 TEMPS APPROACHING 30 BY END OF WEEK. && .AVIATION...25/18Z MCS MOVED THROUGH EARLY THIS MORNING ACROSS SOUTHERN IOWA AND IS NOW WELL SOUTHEAST ACROSS MISSOURI AND ILLINOIS. AREAS OF IFR CEILINGS JUST NORTH OF THE CONVECTIVE COMPLEX SHOULD DISSIPATE EARLY THIS AFTERNOON LEAVING AREAS OF CU AND MID/HIGH CLOUDS. WARM FRONT SHOULD REMAIN SOUTH OF IOWA TONIGHT. EASTERLY BOUNDARY LAYER UP TO 925 MB SHOULD PREVAIL NORTH OF THE BOUNDARY. MODEL SOUNDINGS FROM BOTH 12Z NAM/GFS INDICATE SATURATED CONDITIONS IN THIS LAYER. FAVORED AREA NORTH OF BOUNDARY FOR FOG/STRATUS. FOR NOW...FORECASTED FOG...BUT NOT DENSE...AND STRATUS DURING THE OVERNIGHT HOURS. && .HYDROLOGY... POTENTIAL FOR HEAVY RAINFALL IS A CONCERN OVER THE NEXT FEW DAYS. INITIAL COMPLEX TODAY MAY BRING LOCALLY HEAVY RAFL TO THE SRN AND SWRN PART OF THE STATE. FFG VALUES HAVE INCREASED OVR THE SOUTH THIS WEEK WITH MOST AREAS IN THE 1.5 INCH RANGE FOR 1 HR AND AROUND 2 INCHES OR MORE FOR 3 HOUR SUGGEST POTENTIAL FOR FLASH FLOODING IS LOW...BUR RISES IN AREAS STREAMS IS QUITE LKLY. HIGH PWAT VALUES...APPROACHING 2 INCHES ALNG THE MO BORDER NEED TO BE MONITORED. NEXT ROUND ON MON LOOKS LIKE IT WILL BE OVR THE NERN ZONES...WHERE FLASH FLOODING POTENTIAL IS LOWER.
