What forecasters said that day

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

NWS Des Moines, IA wrote its last area forecast discussion before this flash flood warning went out at Jun 5, 2:45 AM CDT, 0 minutes earlier.

Area forecast discussion, Jun 5, 2:45 AM CDT, 0 minutes before

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE DES MOINES IA
245 AM CDT SAT JUN 5 2010

.DISCUSSION...
PRIMARY CONCERN REMAINS DURING THE SHORT TERM THROUGH THIS MORNING.
VERY EFFICIENT RAIN PRODUCING THUNDERSTORMS HAVE BEEN MOVING OVER
THE SOUTHWEST COUNTY WARNING AREA OVERNIGHT. LAMONI HAD 2.80 INCHES
OF RAIN IN LESS THAN AN HOUR AND SUSPECT A FEW LOCATIONS OVER
SOUTHERN RINGGOLD SURPASSED THAT HOURLY TOTAL. PRECIPITABLE WATER
VALUES ARE NOW OVER 2 INCHES IN THIS REGION. STRONG 850 THETA-E
ADVECTION NOW ONGOING AND 850 MB DEWPOINTS ARE NOW NEAR 18C. THIS
REGION IS EXPECTED TO LIFT AS THE LOW LEVEL JET 50 KT CONTINUES TO
INTENSIFY AND LIFT NORTH BETWEEN 06-12Z. WARM CLOUD DEPTHS TO NEAR
15 KFT WILL AID IN EFFICIENT RAIN PRODUCING STORMS THUS FLASH
FLOODING AND RIVER FLOODING REMAIN A CONCERN.

SEVERE THREAT EXISTS YET TONIGHT AS NEAR SFC BASED STORMS CONTINUE
AND CONDITIONS ARE BECOMING INCREASING FAVORABLE FOR A BRIEF TORNADO
WITH EFFECTIVE SRH VALUES NOW OF 300-400 M2/S2 WITH A NEAR SFC
INFLOW BASE AND LOWERING LCL VALUES BELOW 1000 M. LARGE HAIL AND
DAMAGING WINDS ALSO POSSIBLE. SPC HAS ISSUED A MODERATE RISK FOR THE
FAR SOUTHEAST FOR THIS AFTERNOON AND EVENING. STILL A LOT OF
UNCERTAINTY WHERE THE SFC BOUNDARY WILL BE THIS AFTERNOON AND HOW
MUCH RECOVERY OCCURS. GIVEN STRENGTH OF THE LLJ...THE BOUNDARY
SHOULD BE ABLE TO LIFT NORTH INTO CENTRAL IOWA AND OVERCOME ONGOING
STORMS AND ASSOCIATED COLD POOLS TO THE SOUTH. THIS SHOULD ALLOW THE
SOUTH TO BECOME QUITE UNSTABLE BY THIS AFTERNOON WITH A GOOD CHANCE
OF SUPERCELLS DEVELOPING AND A SIGNIFICANT SEVERE WEATHER RISK.

HIGH PRESSURE RIDGE WILL MOVE INTO THE CENTRAL AND WEST TONIGHT AND
SUNDAY. THERE IS THE POTENTIAL FOR A FEW NORTHWEST FLOW STORMS TO
CLIP THE NORTHEAST SUNDAY. THE HIGH PRESSURE WILL SHIFT EAST SUNDAY
NIGHT THEN ANOTHER CHANCE FOR STORMS BY MONDAY.

NO CHANGES BEYOND MONDAY DUE TO TIME CONSTRAINTS TONIGHT DUE TO
ONGOING WEATHER.

&&

.AVIATION...
05/06Z...NEXT ROUND OF THUNDERSTORMS BEGINNING TO DEVELOP ACROSS THE
SOUTHERN CWA...WITH SOME ADDITIONAL DEVELOPMENT MOVING INTO WESTERN
IOWA. ACTIVITY TO SPREAD ACROSS ENTIRE CWA THROUGHOUT THE OVERNIGHT
HOURS. INSTABILITY NOT AS GREAT ACROSS THE NORTHERN CWA...SO REMOVED
THUNDER MENTION FROM KFOD AND KMCW. KFOD AND KALO WILL BE ON THE
NORTHERN EXTEND OF THE LIGHTNING...SO WILL HAVE TO MONITOR FOR
POSSIBLE CHANGES. OTHERWISE EXPECTED TO SEE SOME STRONG STORMS MOVE
THROUGH KDSM AND KOTM THROUGH THE FIRST 6 TO 12 HOURS OF THE TAF
PERIOD WITH HEAVY RAINFALL POSSIBLE AS WELL. LINGERING THUNDERSTORM
CHANCES EXPECTED INTO SATURDAY/EARLY SATURDAY EVENING BEFORE HIGH
PRESSURE BUILDS INTO THE AREA SATURDAY NIGHT.
