...A FLASH FLOOD WARNING REMAINS IN EFFECT UNTIL 700 PM CDT FOR
BENTON...CAMDEN...CEDAR...DADE...DALLAS...HICKORY...MILLER...
MORGAN...POLK AND ST. CLAIR COUNTIES...

AT 353 PM CDT...THE PUBLIC REPORTED THAT EXCESSIVE RAINFALL WAS 
PRODUCING FLASH FLOODING ACROSS THE WARNED AREA. SEVERAL ROADS IN 
BENTON COUNTY WERE BEGINNING TO FLOOD DUE TO THE EXCESSIVE RAINFALL 
TODAY. ALTHOUGH RAINFALL AMOUNTS OF ONE HALF TO LOCALLY 1.50 INCHES 
HAS FALLEN SINCE THIS MORNING...SATURATED SOIL CONDITIONS AND RUNOFF 
HAS ALLOWED FOR FLASH FLOODING TO DEVELOP. 

SEVERAL WAVES OF MODERATE TO HEAVY RAINFALL WILL CONTINUE ACROSS THE 
WARNED AREA THROUGH THIS EVENING. THIS WILL AGGRAVATE THE ALREADY 
SATURATED SOILS AND CAUSE ADDITIONAL FLASH FLOODING IN THE WARNED 
AREA. RAINFALL RATES WILL AVERAGE BETWEEN ONE AND THREE TENTHS OF AN 
INCH PER HOUR...WITH LOCALLY ONE INCH PER HOUR NEAR THUNDERSTORMS. 

UNTIL THE MAIN WEATHER SYSTEM ACROSS WESTERN OKLAHOMA MOVES EAST OF 
THE REGION...PERIODS OF THUNDERSTORMS WILL CONTINUE TO DEVELOP. 

RUNOFF FROM THIS EXCESSIVE RAINFALL IS CAUSING FLASH FLOODING. SOME
LOCATIONS THAT MAY EXPERIENCE FLASH FLOODING INCLUDE...BOLIVAR...
BUFFALO...CAMDENTON...EL DORADO SPRINGS...ELDON...GREENFIELD...
HERMITAGE...OSAGE BEACH...STOCKTON...VERSAILLES...WARSAW...COLE
CAMP...EVERTON...FAIR PLAY AND HUMANSVILLE.

FLOODING IS OCCURRING OR IS IMMINENT. MOST FLOOD RELATED DEATHS OCCUR
IN AUTOMOBILES. DO NOT ATTEMPT TO CROSS WATER COVERED 
BRIDGES...DIPS...OR LOW WATER CROSSINGS.

TO REPORT FLOODING...HAVE THE NEAREST LAW ENFORCEMENT AGENCY RELAY
YOUR REPORT TO THE NATIONAL WEATHER SERVICE FORECAST OFFICE IN
SPRINGFIELD.

AREA FORECAST DISCUSSION

1244 PM CDT WED MAY 7 2008

...UPDATE TO AVIATION...

.UPDATE...

A MASS OF MODERATE TO HEAVY RAIN WITH EMBEDDED THUNDERSTORMS
CONTINUES TO PUSH NORTHEAST ACROSS THE CWA. STRONGER THUNDERSTORMS
ARE BEING FED BY ELEVATED CAPE ON THE ORDER OF 1400 TO 1600 J/KG
WITH A PARCEL INITIATING INVOF 850 HPA. HAVE ISSUED ISOLATED
SEVERE THUNDERSTORM WARNINGS...WITH A COUPLE SIG WX ALERTS AS WELL
FOR REPORTS OF DIME SIZE HAIL AND RADAR DETECTED VELOCITIES AROUND
50 KNOTS. THE DIME HAIL FELL FROM A CORE OF ABOUT 55 DBZ TO 25K
FT. CURRENT RADAR RAINFALL ESTIMATES ARE SLIGHTLY OVERESTIMATED
WITH THE TRUE RAINFALL AT APPROXIMATELY 80 PERCENT OF THE RADAR
ESTIMATE. REPORTS TO 1.60 INCHES HAVE BEEN RECEIVED OVER BARTON
COUNTY AS OF 11 AM...INCLUDING 1.20 INCHES IN 45 MINUTES IN LAMAR.

THIS INITIAL PRECIPITATION BLOB WILL CONTINUE NORTHEAST. A SLIGHT
DECREASE IN PRECIP COVERAGE AND INTENSITY WILL BE EVIDENT IN ITS
WAKE...CURRENTLY SHOWING UP OVER NORTHEAST OKLAHOMA...DUE TO UPPER
LEVEL CONVERGENCE BEHIND THE INITIAL SHORT WAVE ENERGY. SECONDARY
SHORT WAVE TROUGH IS HOT ON ITS HEALS...PRODUCING WIDESPREAD
MODERATE TO HEAVY RAIN WITH EMBEDDED THUNDERSTORMS OVER THE
NORTHEASTERN TWO THIRDS OF OKLAHOMA. THIS ACTIVITY IS NOT EXPECTED
TO CHANGE MUCH AS IT WORKS INTO THE SGF CWA. THE POTENTIAL FOR AN
ISOLATED SEVERE STORM WILL LIKELY PERSIST AS MUCAPES MAINTAIN
THEMSELVES IN THE 1000 J/KG RANGE DESPITE A SLIGHT DECREASE IN
MIDLEVEL LAPSE RATES.

QUESTIONS ARISE AFTER THIS SECOND BIT OF ENERGY PUSHES THROUGH. THERE
IS CURRENTLY A SHARP EDGE TO THE REAR OF THE PRECIPITATION SHIELD
WITH SURFACE TEMPERATURES WARMING SLIGHTLY IN ADVANCE OF THE
SURFACE LOW PRESSURE CENTER. IT IS LIKELY THAT THIS TREND WILL
CONTINUE TO THE NORTHEAST AS THE SURFACE LOW EJECTS...PERHAPS
MAKING IT POSSIBLE TO ERODE SURFACE BASED INHIBITION OVER THE
SOUTHERN CWA DURING THE LATE AFTERNOON AND EARLY EVENING HOURS.
WITH A MARKED INCREASE IN 0-1 AND 0-6 KM SHEAR DURING THIS
PERIOD...THERE IS STILL A CHANCE FOR SUPERCELL FORMATION...AND
HAVE KEPT THE POSSIBILITIES FOR ISOLATED TORNADOES IN THE FORECAST
OVER SOUTHERN ZONES FOR THIS REASON.

.DISCUSSION...

A COMPLEX WEATHER SCENARIO CONTINUES TO EVOLVE EARLY WEDNESDAY.
THE REMNANTS OF A CONVECTIVE COMPLEX THAT DEVELOPED OVER KANSAS WAS
SPREADING INTO PORTIONS OF CENTRAL AND SOUTHERN MISSOURI EARLY
THIS MORNING. REGIONAL RADAR AND SATELLITE SHOW OTHER LARGE
CONVECTIVE CLUSTERS ACROSS THE PLAINS THAT HAD DEVELOPED IN
RESPONSE TO A BROAD LOW LEVEL JET AHEAD OF AN UPPER LOW TRACKING
OUT OF THE DESERT SOUTHWEST.

THIS POTENT SYSTEM WILL MIGRATE NORTHEASTWARD ACROSS THE SOUTHERN
PLAINS TODAY. INCREASING UPPER DIFFLUENCE WILL OVERSPREAD THE
REGION DURING THE DAY AND INTERACT WITH A STRENGTHENING LOW LEVEL
JET TO PROVIDE AMPLE LIFT FOR WIDESPREAD CONVECTION. EXPECT TO SEE
CLUSTERS OF CONVECTION DEVELOP FROM THE SOUTHERN PLAINS INTO THE
MISSOURI VALLEY THROUGH THE DAY...AND INITIALLY BECOME FOCUSED ALONG
A DEVELOPING FRONTAL ZONE AS SEEN IN THE PROGGED 925-850 MB WIND
FIELDS. THE AXIS OF MAXIMIZED MASS CONVERGENCE WILL EXTEND FROM
THE APPROACHING UPPER LOW INTO SOUTHEAST AND CENTRAL MISSOURI BY
THIS AFTERNOON. MODEL SOUNDINGS SUGGEST VERY EFFICIENT RAINFALL
PRODUCTION WITH NEARLY SATURATED AIRMASS THROUGH 400 MB AND
PRECIPITABLE WATER VALUES AROUND 1.5 INCHES. THE RISK OF FLASH
FLOODING WILL INCREASE DURING THE DAY PARTICULARLY FROM SOUTHEAST
KANSAS INTO THE LAKE OF THE OZARKS REGION AS REPEATED ROUNDS OF
CONVECTION ARE LIKELY TO DEVELOP.

A SURFACE LOW WILL DEVELOP OVER THE SOUTHERN PLAINS TODAY AND
TRACK INTO THE OZARKS TONIGHT WITH THE UPPER LOW. EXPECT A BAND OF
STRONG TO SEVERE CONVECTION TO DEVELOP ALONG THE ATTENDANT COLD
FRONT/DRY LINE AND SPREAD EAST INTO SOUTHERN MISSOURI LATE THIS
AFTERNOON AND EVENING. INSTABILITY WILL BE HAMPERED SOMEWHAT BY
CLOUD COVER AND ONGOING CONVECTION BUT SHEAR PROFILES WILL BECOME
MORE FAVORABLE WITH THE APPROACH OF THE UPPER LOW. MODEL SOUNDINGS
SUGGEST DAMAGING WINDS WILL BE THE PRIMARY THREAT WITHIN A LINEAR
COMPLEX THAT WILL SWEEP EAST ACROSS THE OZARK THIS EVENING.
ISOLATED TORNADOES CANNOT BE RULED OUT GIVEN THE ENHANCED LOW
LEVEL HELICITIES DUE TO BACKING LOW LEVEL WINDS AHEAD OF THE
APPROACHING SURFACE LOW AND LOW CONDENSATION LEVELS.

MEANWHILE AN AXIS OF MODERATE TO HEAVY RAINFALL IS PROGGED TO SET
UP WITHIN DEFORMATION ZONE ON THE NORTHERN SIDE OF THE UPPER LOW
TRACK. MODELS CONTINUE TO BRING THIS AXIS OF HEAVY RAINFALL ACROSS
SOUTHEAST KANSAS AND CENTRAL MISSOURI. HAVE FOLLOWED CLOSE TO HPC
AND MODEL GUIDANCE WHICH IS DEPICTING 3 TO 4 INCHES OF RAIN IN
THIS AREA. RAINFALL AMOUNT OF 1 TO 2 INCHES WILL BE MORE COMMON
FARTHER SOUTH. WHILE LOCALIZED FLOODING WILL BE POSSIBLE ANYWHERE
ACROSS THE MISSOURI OZARKS AND SOUTHEAST KANSAS...THE GREATEST
RISK OF SIGNIFICANT FLASH FLOODING WILL AFFECT AREAS GENERALLY
NORTH OF A NEOSHO TO ROLLA LINE WHERE A FLASH FLOOD WATCH REMAINS
IN EFFECT. SERIOUS FLASH FLOODING AS WELL AS RIVER FLOODING WILL
LIKELY DEVELOP IF THE FORECAST RAINFALL AMOUNTS MATERIALIZE.

SHOWERS WILL PERSIST INTO THURSDAY MORNING AS THE UPPER LOW PULLS
AWAY. A ZONAL FLOW PATTERN WILL SET UP IN THE WAKE OF THE EXITING
LOW AND BRING ANOTHER MINOR SHORTWAVE INTO THE PLAINS THURSDAY
NIGHT. MODELS CONTINUE TO DEPICT A CONVECTIVE COMPLEX THAT WILL
DEVELOP OVER KANSAS AND MOVE INTO SOUTHWEST FRIDAY EARLY FRIDAY.

ANOTHER MORE POTENT SHORTWAVE AND ASSOCIATED FRONT WILL SWEEP
ACROSS THE REGION SATURDAY BRINGING YET ANOTHER CHANCE OF
CONVECTION.

.AVIATION...

FOR THE 18Z TAFS...HAVE KEPT IFR TO LIFT CEILINGS GOING THROUGH
MOST OF FORECAST FOR BOTH SPRINGFIELD AND JOPLIN AS AIRMASS
REMAINS HIGHLY SATURATED AHEAD OF ADVANCING UPPER LOW CURRENTLY
OVER WEST TEXAS. WILL KEEP TEMPO GROUPS GOING THROUGH MID TO LATE
EVENING AS ANOTHER CLUSTER OF STORMS DEVELOPING OVER CENTRAL AND
NORTHEAST OKLAHOMA MOVES NORTHEAST TOWARD THE AIRPORTS. THEREAFTER
WILL CARRY VICINITY THUNDER AND LET LATER SHIFTS GET MORE SPECIFIC
WITH STORM TIMING OVERNIGHT.

1209 PM CDT WED MAY 7 2008

THIS HAZARDOUS WEATHER OUTLOOK IS FOR PORTIONS OF THE MISSOURI
OZARKS AND EXTREME SOUTHEAST KANSAS.

.DAY ONE...THIS AFTERNOON AND TONIGHT.

  WEATHER HAZARDS EXPECTED:

  NUMEROUS THUNDERSTORMS CAPABLE OF PRODUCING VERY HEAVY
  RAINFALL...WIND GUSTS TO 50 MPH AND SMALL HAIL.

  A FEW SEVERE THUNDERSTORMS CAPABLE OF PRODUCING DAMAGING WINDS
  IN EXCESS OF 60 MPH...HAIL TO THE SIZE OF HALF DOLLARS...AND
  POSSIBLY ISOLATED TORNADOES.

  TORRENTIAL RAINFALL AMOUNTS OF 2 TO 4 INCHES AND FLASH
  FLOODING.

  AREAS AFFECTED AND TIMING:

  THUNDERSTORMS WILL INCREASE THROUGH THE DAY ACROSS THE OUTLOOK
  AREA. THE GREATEST RISK OF SEVERE STORMS WILL OCCUR ACROSS
  SOUTHERN MISSOURI...OR SOUTH OF A LINE FROM LAMAR TO ROLLA.

  DISCUSSION:

 NUMEROUS THUNDERSTORMS WILL CONTINUE TO DEVELOP AND MOVE OVER THE
 SAME AREAS TODAY AS A STRONG STORM SYSTEM TRACKS OUT OF THE
 SOUTHERN PLAINS. A FEW SEVERE THUNDERSTORMS MAY BE EMBEDDED
 WITHIN THE WIDESPREAD ACTIVITY. WIND GUSTS TO 60 MPH AND HAIL TO
 THE SIZE OF QUARTERS WILL BE THE MAIN THREATS WITH THESE
 THUNDERSTORMS.

 THE POTENTIAL OF STRONG TO SEVERE STORMS WILL INCREASE LATE THIS
 AFTERNOON INTO THE EVENING HOURS AS WIND SHEAR INCREASES IN
 ADVANCE OF THE APPROACHING STORM SYSTEM...AND SURFACE LOW
 PRESSURE TRACKS INTO FAR SOUTHWESTERN MISSOURI. A LINE OF STRONG
 TO SEVERE STORMS WILL LIKELY MOVE OUT OF OKLAHOMA AND INTO
 SOUTHERN MISSOURI LATER THIS AFTERNOON AND EVENING. LOCALIZED
 DAMAGING WINDS TO 60 MPH AND HAIL TO THE SIZE OF HALF DOLLARS
 WILL BE THE PRIMARY THREATS WITH THESE STORMS. HOWEVER...AN
 ISOLATED TORNADO CANNOT BE RULED OUT...PARTICULARLY IF
 TEMPERATURES CAN WARM INTO THE 70S IN ADVANCE OF THIS
 THUNDERSTORM ACTIVITY.

 IN ADDITION...HEAVY RAINFALL WILL BECOME A SIGNIFICANT HAZARD
 WITH WIDESPREAD AMOUNTS OF 2 TO 4 INCHES LIKELY. LOCALIZED
 AMOUNTS TO 5 INCHES WILL BE POSSIBLE...ESPECIALLY ALONG AND NORTH
 OF INTERSTATE 44. FLASH FLOODING AND RIVER FLOODING WILL BE
 LIKELY ACROSS MUCH OF EXTREME SOUTHEAST KANSAS AND THE MISSOURI
 OZARKS THIS AFTERNOON AND TONIGHT.

.DAYS TWO THROUGH SEVEN...THURSDAY THROUGH TUESDAY.

 FLOODING OF SMALL STREAMS...LOW WATER CROSSINGS...AND RIVERS MAY
 BE ONGOING THURSDAY.

 THUNDERSTORMS WILL BE POSSIBLE LATE THURSDAY NIGHT THROUGH SUNDAY. A
 FEW OF THESE STORMS MAY BECOME SEVERE.

.SPOTTER INFORMATION STATEMENT...

 SPOTTER ACTIVATION MAY BE NEEDED LATER THIS AFTERNOON AND
 EVENING ACROSS FAR SOUTHERN MISSOURI.
