...FLASH FLOOD WARNING CONTINUES FOR SOUTHWESTERN LAWRENCE AND 
NORTHEASTERN NEWTON COUNTIES UNTIL 730 PM CDT...

AT 234 PM CDT...NATIONAL WEATHER SERVICE DOPPLER RADAR CONTINUED TO 
SHOW THUNDERSTORMS WITH VERY HEAVY RAINFALL ACROSS FAR NORTHEAST 
NEWTON COUNTY. DOPPLER RADAR ESTIMATES INDICATE THAT THESE 
THUNDERSTORMS ARE PRODUCING RAINFALL RATES OF 2 TO 3 INCHES PER 
HOUR...AND THIS IS FALLING ON TOP OF THE 2 INCHES THAT ALREADY FELL. 
LOCATIONS JUST SOUTH AND SOUTHWEST OF WENTWORTH HAVE LIKELY PICKED 
UP THREE AND A HALF TO 5 INCHES OF RAIN BETWEEN 1230 PM AND 230 PM. 

THIS IS A VERY DANGEROUS FLOODING SITUATION. FLASH FLOODING IS 
OCCURRING OR IMMINENT OVER NORTHEAST NEWTON COUNTY WITH ROADS LIKELY 
BECOMING IMPASSABLE. THE HEAVIEST RAIN HAS FALLEN OVER HIGHWAYS 
JJ...J...AND HIGHWAY W. 

TORRENTIAL RAINFALL OF THIS MAGNITUDE CAN LEAD TO VERY RAPID RISES 
ON CREEKS AND SMALL STREAMS WHICH COULD WASH AWAY ROADWAYS OR 
BRIDGES. DO NOT UNDERESTIMATE THE POWER OF FLOOD WATERS. ONLY A FEW 
INCHES OF RAPIDLY FLOWING WATER CAN QUICKLY CARRY AWAY YOUR VEHICLE.

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE SPRINGFIELD MO
1048 AM CDT SAT SEP 3 2005

.UPDATE...

MADE A COUPLE OF VERY MINOR TWEAK TO GOING GRIDS. FIRST...TEMPS
RUNNING A BIT AHEAD OF THIS TIME YESTERDAY AND OUR MORNING SOUNDING
DOES SHOW TEMPS 1-2C WARMER THAN 24 HOURS AGO FROM 950-850MB. NUDGED
TEMPS UPWARD SOME TO AT LEAST YESTERDAYS LEVELS AND A DEGREE OR TWO
WARMER THAN YESTERDAY IN SPOTS.

SECOND TWEAK WAS TO DELAY ONSET OF ISOLATED CONVECTION UNTIL THIS
AFTERNOON AND EXPAND THE AREA TO INCLUDE WEST CENTRAL MISSOURI. 12Z
SOUNDING SHOWS SOME FAIRLY STEEP LAPSE RATES FROM JUST ABOVE THE
BOUNDARY LAYER UP TO NEARLY 500 MB. MODIFYING THE SOUNDING FOR
AFTERNOON HEATING/MIXING YIELDS MLCAPES BETWEEN 1000-1500 J/KG WITH
NO INHIBITION. 15Z SURFACE STREAMLINE ANALYSIS DOES SHOW A
CONVERGENCE AXIS SETTING UP ROUGHLY ALONG THE KS/MO BORDER WHICH
COULD SERVE AS A FOCUSING MECHANISM FOR CONVECTION THIS AFTERNOON.
ALSO DIFFERENTIAL HEATING BETWEEN THE HIGHER TERRAIN OF THE PLATEAU
AND LOWER ELEVATIONS COULD LEAD TO SOME LOCALIZED CONVERGENCE AND
ISOLATED CONVECTION DEVELOPING OVER THE WESTERN PORTIONS OF THE
PLATEAU.

IZZI

.AVIATION...

FOR THE 18Z TAFS...VFR CONDITIONS WILL GENERALLY BE THE RULE OVER
THE NEXT 24 HOURS. THERE IS AN OUTSIDE CHANCE THAT AN ISOLATED STORM
COULD AFFECT EITHER TERMINAL THIS AFTERNOON...BUT THE CHANCES ARE
FAR TOO LOW TO WARRANT INCLUSION IN THE TAFS. WILL AMEND IF STORMS
APPEAR IMMINENT.

IZZI

.PREV DISCUSSION...

PRIMARY FORECAST CHALLENGE IS CHANCE FOR CONVECTION THIS AFTERNOON.
WATER VAPOR IMAGERY AND PROFILERS SHOW SHORTWAVE OVER WESTERN KANSAS
EARLY THIS MORNING...WITH GRANADA PROFILER CONFIRMING A WELL DEFINED
MID LEVEL SHORTWAVE PASSAGE AT ABOUT 01Z. NAM INITIALIZED THIS
FEATURE WELL...AND SHOWS IT MOVING VERY SLOWLY EASTWARD TODAY. NAM
DOES BREAK OUT SOME LIGHT CONVECTIVE PRECIP OVER FAR SW MO THIS
AFTERNOON AHEAD OF THIS SHORTWAVE. LOOKING AT ETABUFR SOUNDINGS...
WITH SURFACE TEMPS IN THE UPPER 80S AND DEWPOINTS IN THE MID
60S...MLCAPES PUSH 1000 J/KG WITH VIRTUALLY NO CAP. THINK THAT GOING
SLIGHT CHANCE POPS OVER FAR SRN COUNTIES LOOKS GOOD. WITH A
RELATIVELY WIDE DEWPOINT DEPRESSION IN THE LOWEST 200 MB THIS
AFTERNOON...THINK THAT ISOLATED SEVERE WIND GUSTS ARE ALSO
POSSIBLE. WINDEX GIVES A MAXIMUM POTENTIAL GUST OF 69 KNOTS...SO
WILL PUT IN HWO EVEN THOUGH COVERAGE OF CONVECTION WILL BE 20
PERCENT AT BEST.

REMAINDER OF THE FORECAST LOOKS BENIGN...WITH SUBTROPICAL RIDGE
BUILDING INTO THE AREA ON SUNDAY...AND RIDGE AXIS REMAINING NEAR OR
DIRECTLY OVER THE REGION THROUGH MUCH OF THE UPCOMING WORK WEEK. A
VIGOROUS SHORTWAVE DOES DIG INTO THE NRN HIGH PLAINS TOWARDS
FRIDAY...BUT SHOULD SLIDE WELL TO OUR NORTH.
