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 Springfield, MO wrote its last area forecast discussion before this flash flood warning went out at Sep 15, 3:10 AM CDT, 2 hours 45 minutes earlier.

Area forecast discussion, Sep 15, 3:10 AM CDT, 2 hours 45 minutes before

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE SPRINGFIELD MO
310 AM CDT THU SEP 15 2005

.DISCUSSION...
FIRST WAVE OF CONVECTION MAKING ITS WAY THROUGH THE FORECAST
AREA...AND HAVE MADE SOME ADJUSTMENTS FOR THIS IN THE SHORT TERM
GRIDS. CONVECTION IS ELEVATED...AND IS MOVING AT A NICE CLIP AS
LEAD SHORTWAVE MOVES ENE THROUGH THE AREA AHEAD OF THE STRONGER
SHORTWAVE NOW OVER WESTERN KS. FIRST AREA OF RAIN MAY CLEAR A GOOD
CHUNK OF THE CWA BEFORE 1200 GMT.

NEXT AREA OF RAIN ASSOCIATED WITH STRONG SHORTWAVE OVER WESTERN KS
WILL MOVE THROUGH THE AREA TODAY...EXITING THE AREA LATE THIS
AFTERNOON AND THIS EVENING. HAVE CATEGORICAL RAIN CHANCES IN
MOST...IF NOT ALL AREAS...TAPERING THE RAIN OFF FROM SW-NE THIS
AFTERNOON AND EARLY TONIGHT.

HEAVY RAIN AND POSSIBLE FLOODING THE MOST OBVIOUS CONCERN IN THE
NEAR TERM. STRONGLY DIFFLUENT FLOW ALOFT IN THE RIGHT ENTRANCE
REGION OF THE UPPER JET IS COUPLED WITH DEEP MOISTURE (PROGGED
PRECIPITABLE WATER VALUES OF 1.8-1.9). LOOKS AS THOUGH HEAVIEST RAIN
WILL OCCUR THIS MORNING ALONG AND AHEAD OF THE 850MB LOW TRACK ON
THE MO OZARK PLATEAU WHERE ISENTROPIC LIFT WILL BE MAXIMIZED. POINT
SOUNDINGS STILL INDICATE SOME MODEST ELEVATED INSTABILITY...BUT THAT
DECREASES WITH TIME THIS MORNING. PREVIOUS THINKING HAS BEEN THAT
WITH RECENT GENERALLY DRY CONDITIONS OVER THE REGION...NOT TO GO
WITH A FLOOD WATCH...HOWEVER...STARTING TO RETHINK THIS FOR TODAY.
AT THE VERY LEAST WILL MENTION HEAVY RAIN IN THE ZONE FORECAST AND
HAZARDOUS WEATHER OUTLOOK.

MAY TAKE A WHILE FOR LOW CLOUDS TO CLEAR IN THE WAKE OF THE UPPER
SYSTEM TONIGHT. CLEARING SHOULD OCCUR OVER WESTERN PORTIONS OF THE
CWA TONIGHT AS HIGH PRESSURE BUILDS INTO THE REGION AHEAD OF 500MB
FLAT RIDGE. HAVE PUT FOG IN THE FORECAST FOR THE WESTERN
MO/SOUTHEAST KS. WILL ALSO MENTION SOME THE CHANCE OF SHALLOW
RADIATION FOG AGAIN FRIDAY NIGHT WITH SURFACE HIGH OVER EASTERN MO.

ADJUSTED TEMPERATURES DOWN FROM PREVIOUS FORECAST FOR THE NEXT
COUPLE OF DAYS...BUT WARM WEATHER WILL RETURN OVER THE UPCOMING
WEEKEND AS FLAT UPPER LEVEL RIDGE BUILDS INTO THE AREA AND LOW LEVEL
WARM ADVECTION KICKS IN. ZONAL FLOW WILL REMAIN IN PLACE OVER THE
REGION INTO EARLY NEXT WEEK. BOTH THE NAM AND AND THE GFS DEVELOP A
LEE SIDE LOW OVER THE CENTRAL HIGH PLAINS OVER THE WEEKEND WITH
DECENT ISENTROPIC UPGLIDE MOVING INTO THE AREA LATE SATURDAY AND
SUNDAY WITH THE APPROACH OF THE NEXT SURFACE FRONT. LOW LEVEL
MOISTURE NOT OVERLY ABUNDANT LATE SATURDAY...BUT WILL CONTINUE TO GO
WITH LOW RAIN CHANCES FOR THE NORTHERN CWA LATE IN THE UPCOMING
WEEKEND. DSA

&&

.AVIATION...
06Z TAFS...SHORT TERM CONCERNS DEAL WITH ONGOING CONVECTION ACROSS
WESTERN MISSOURI AND SOUTHEAST KANSAS. CEILINGS AND VISIBILITIES
WILL BE IFR AT TIMES...ESPECIALLY THE NEXT FEW HOURS AS THE COMPLEX
MOVES EASTWARD. ADDITIONAL DEVELOPMENT ACROSS CENTRAL OKLAHOMA AND
CENTRAL KANSAS WILL BEGIN TO AFFECT PORTIONS OF THE OZARKS AND
SOUTHEAST KANSAS THIS MORNING. HAVE KEPT MVFR/IFR CONDITIONS
THROUGHOUT THE DAY DUE TO THE PERSISTENT LOW LCL AND LIFT ACROSS THE
REGION. LATER SHIFTS WILL NEED TO RE-EVALUATE FOG POTENTIAL
OVERNIGHT.
