857 AM CDT SAT JUL 4 2009

...FLASH FLOOD WARNING FOR REMAINS IN EFFECT FOR SOUTHERN HOWARD AND
NORTHERN COOPER COUNTIES UNTIL NOON CDT...

AT 853 AM CDT...NATIONAL WEATHER SERVICE DOPPLER RADAR ALONG WITH 
TRAINED WEATHER SPOTTERS REPORTED IN EXCESS OF 3.5 INCHES OF RAIN 
HAD FALLEN ACROSS THE WARNING AREA SINCE 4 AM.  THIS HEAVY RAIN HAS 
LED TO EXTREMELY RAPID RISES ON AREA STREAMS...CREEKS AND RIVERS IN 
THE AREA.  ADDITIONAL SHOWERS AND THUNDERSTORMS ARE POSSIBLE THROUGH 
THE MORNING HOURS...HOWEVER ACCUMULATIONS ARE EXPECTED TO REMAIN 
LESS THAN ONE QUARTER INCH.

SOME LOCATIONS THAT WILL EXPERIENCE FLOODING INCLUDE...BOONVILLE...
NEW FRANKLIN AND PILOT GROVE.

PRECAUTIONARY/PREPAREDNESS ACTIONS...

DO NOT DRIVE YOUR VEHICLE INTO AREAS WHERE THE WATER COVERS THE
ROADWAY. THE WATER DEPTH MAY BE TOO GREAT TO ALLOW YOUR CAR TO CROSS
SAFELY.

IN HILLY TERRAIN...THERE ARE HUNDREDS OF LOW WATER CROSSINGS WHICH
ARE POTENTIALLY DANGEROUS IN HEAVY RAIN. DO NOT ATTEMPT TO TRAVEL
ACROSS FLOODED ROADS. FIND ALTERNATE ROUTES. IT ONLY TAKES A FEW
INCHES OF SWIFTLY FLOWING WATER TO CARRY VEHICLES AWAY.

REPORT FLOODING TO THE NEAREST LAW ENFORCEMENT AGENCY SO THAT THEY
MAY TAKE APPROPRIATE ACTION TO CLOSE FLOODED ROADWAYS. THEY WILL
RELAY YOUR REPORT TO THE NATIONAL WEATHER SERVICE IN PLEASANT HILL.

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE KANSAS CITY/PLEASANT HILL MO
345 AM CDT SAT JUL 4 2009

.DISCUSSION...

MAIN FORECAST CHALLENGE FOCUSES ON THE VERY NEAR TERM WITH A FRONT
MOVING THROUGH THE FORECAST...PRECIPITATION CHANCES CONTINUING AND
TEMPERATURES IN THE WAKE OF THE FRONT.

INDEPENDENCE DAY:
A LINE OF STORMS THAT FORMED EARLIER IN THE NIGHT WAS SLOWLY
DRIFTING SOUTHWARD. THIS CONVECTION WILL LIKELY SHIFT THE FOCUS FOR
THIS AFTERNOONS STORMS A BIT FURTHER SOUTH. UNTIL THEN THE CURRENT
LINE SHOULD PERSIST THROUGH THE LATE MORNING HOURS OR INTO THE EARLY
AFTERNOON WHILE CONTINUING ITS SLOW SOUTHWARD PROPAGATION. THIS
SEEMED TO BE FOCUSED ON AN AREA OF ISENTROPIC LIFT FROM AROUND 306K
TO 310K. MODELS SHOW THIS AREA OF LIFT PERSISTING THROUGH ABOUT 18Z
BEFORE DIMINISHING. SO THE ONGOING PRECIPITATION AREA SHOULD DO
ABOUT THE SAME. THE NEXT QUESTION IS WHERE THE EFFECTIVE BOUNDARY
WILL BE THIS AFTERNOON. MODELS SHOW THAT BY THIS AFTERNOON THE
BOUNDARY WILL BE ACROSS SOUTHERN SECTIONS OF THE FORECAST AREA. THIS
AREA MAY BE A BIT FURTHER SOUTH DUE TO OUTFLOW FROM OVERNIGHT
CONVECTION BUT THE PLACEMENT ACTUALLY SEEMS REASONABLE. WITH THAT IN
MIND...ARRANGED HIGHEST PRECIP CHANCES FOR THE AFTERNOON HOURS FROM
ROUGHLY PAOLA THROUGH SEDALIA INTO NORTH CENTRAL MO. THIS WILL ALSO
LIMIT SEVERE CHANCES TO OUR SOUTHERN ROW OF COUNTIES AND WITH WINDS
VEERED OUT IN THAT AREA FEEL THAT OVER SEVERE CHANCES ARE FAIRLY
LIMITED. EXPECT THE METRO TO BE DRY BY THE AFTERNOON AND WITH A
NORTH WIND BEHIND THE FRONT IT ACTUALLY LOOKS FAIRLY PLEASANT FOR
INDEPENDENCE DAY ACTIVITIES.

SUNDAY THROUGH MONDAY:
NORTHWEST FLOW IS EXPECTED TO REDEVELOP FOR THE REMAINDER OF THE
HOLIDAY WEEKEND AND INTO THE BEGINNING OF THE WORK WEEK. WITH SURFACE
HIGH PRESSURE DOMINATING THE REGION SUNDAY EXPECT DRY CONDITIONS
WITH BELOW NORMAL TEMPERATURES. AS THE HIGH SHIFTS EASTWARD IT SETS
UP A WEAK BOUNDARY IN THE SOUTHERLY RETURN FLOW MONDAY AFTERNOON. AT
THE SAME TIME BOTH THE NAM AND THE GFS BRING A WEAK WAVE THROUGH THE
NORTHWEST FLOW. WITH WEAK CONVERGENCE ON THE BOUNDARY AND WHAT LOOKS
LIKE AN UNCAPPED/NEARLY UNCAPPED AIRMASS A FEW AFTERNOON STORMS ARE
POSSIBLE. THIS AREA WOULD LIKELY BE CONFINED TO THE NORTHERN
PORTIONS OF MISSOURI AND FOR NOW WILL ONLY MENTION SLIGHT CHANCE
POPS.

TUESDAY THROUGH FRIDAY:
WARMER CONDITIONS ARE EXPECTED AS AN UPPER RIDGE SHOULD BUILD OVER
THE SOUTHWESTERN STATES. AFTERNOON HIGHS SHOULD RETURN TO ABOVE
NORMAL VALUES BY MIDWEEK WITH MIDDLE 90S EXPECTED BY THE LATER HALF
OF THE WORK WEEK. AT THIS TIME WILL KEEP THE EXTENDED FORECAST DRY
AS SHORTWAVE AND JET ENERGY STAY TO THE NORTH OF THE AREA. THERE ARE
SOME INDICATIONS THIS MAY BREAK DOWN BY THE END OF THE WEEK BUT WILL
LET FUTURE SHIFTS ADDRESS THIS.

.AVIATION...
FOR THE 06Z TAFS...MODELS HAVE HAD A TOUGH TIME GETTING HANDLE ON
SITUATION. EXTRAPOLATING ONGOING CONVECTION ACROSS CENTRAL KANSAS
AND INTO THE KANSAS CITY AREA...WOULD EXPECT THIS TO CONTINUE FOR
THE NEXT FEW HOURS...ALTHOUGH THERE MAY BE A TREND TO SINK A BIT
FURTHER SOUTH WITH TIME AS PRESSURE FALLS WOULD INDICATE SURFACE
WAVE CURRENTLY IN SOUTH CENTRAL KANSAS WILL MOVE EAST AND MAY
ACTUALLY PASS JUST SOUTH OF THE KANSAS CITY TAF SITES. WILL STILL GO
WITH THE IDEA OF A BRIEF WINDOW OF SOUTHWEST WINDS IN THE MORNING AT
THE KANSAS CITY TAF SITES WITH THE MODELS STILL WANTING TO TRACK THE
SURFACE LOW THROUGH THE REGION...BUT MAY HAVE TO REVISE THAT IDEA
WITH SUBSEQUENT AMENDMENTS IF PRESSURE FALL PATH PROVES TO BE
CORRECT.  WITH A SERIES OF WAVES MOVING ACROSS KANSAS ASSOCIATED
WITH THE ONGOING CONVECTION...MAY SEE A COUPLE OF ROUNDS OF HEAVY
RAIN AT THE TAF SITES.  THINKING DOWNTOWN WILL LIKELY BE MORE IN THE
PATH OF THESE REPEATED STORMS...SO WILL KEEP TEMPO GROUP GOING THE
LONGER AT THAT SITE. FURTHER OUT...THE MAIN QUESTION BECOMES IF WE
WILL KEEP MVFR CIGS THROUGH THE DAY. FOR NOW WILL GO WITH THAT IDEA
GIVEN WHAT IS OCCURRING BEHIND THE FRONT.  HOWEVER WILL NOT BE AS
PESSIMISTIC AS THE NAM WOULD SUGGEST...WITH IFR CIGS MOVING IN LATER
SATURDAY EVENING...BUT SOMETHING TO BE WATCHED.
