AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE TOPEKA KS
424 PM CDT SUN AUG 13 2006

.DISCUSSION...

TONIGHT...AT FORECAST TIME A COLD FRONT WAS DRAPED FROM NORTHWESTERN
IOWA SOUTH THROUGH NORTH CENTRAL KS.  A PREFRONTAL TROUGH POSSIBLE
OUTFLOW BOUNDARY HYBRID WAS LOCATED ALONG A SENECA TO ABILENE
LINE...AND WAS SERVING AS THE FOCAL POINT FOR THUNDERSTORM
DEVELOPMENT AROUND 20Z.  CLEARING AHEAD OF THE FRONT BROUGHT
TEMPERATURES INTO THE UPPER 90S GENERALLY ALONG AND SOUTH OF
INTERSTATE 70 THIS AFTERNOON...BRINGING DEW POINT DEPRESSIONS UP
INTO THE 30 TO 35 DEGREE RANGE.  THIS WOULD ALLOW FOR A DECENT
AMOUNT OF EVAPORATIVE COOLING BELOW THE CLOUD BASE WHICH WOULD
ENHANCE THUNDERSTORM DOWNDRAFTS INTO POSSIBLY DAMAGING SURFACE
WINDS.  SPC HOURLY ANALYSIS INDICATED PRECIPITABLE WATER VALUES OF 2
INCHES ACROSS THE NORTHERN PORTION OF THE CWA.  THESE VALUES HAVE
BEEN SLOWLY INCREASING DURING THE DAY AS SUBTROPICAL MOISTURE POOLS
ALONG THE FRONTAL BOUNDARY.  FORECAST SOUNDINGS INDICATE DEEP
MOISTURE THROUGHOUT THE TROPOSPHERE WILL LEAD TO HIGH PRECIPITATION
EFFICIENCIES ACROSS THE AREA...ADDING TO THE LIKELIHOOD OF HEAVY
RAINFALL ACROSS NORTHEASTERN KS.  WITH 3 HOUR FLASH FLOOD GUIDANCE
VALUES IN THE 3 TO 4 INCH RANGE...WIDESPREAD FLOODING IS
UNLIKELY...HOWEVER LOCALIZED FLOODING WILL REMAIN POSSIBLE IF
STRONGER CELLS TRAIN OVER A PARTICULAR LOCATION.  RAINFALL RATES OF
UP TO 2 INCHES PER HOUR ARE POSSIBLE WITH STRONGER CELLS.  RAINFALL
TOTALS OF AN INCH OR GREATER WILL LIKELY BE COMMON ACROSS THE CWA.

TOMORROW...MODELS HAVE INDICATED STRONG SUBSIDENCE BEHIND THE
FRONTAL BOUNDARY DURING THE DAY TOMORROW.  THIS SHOULD BRING AN END
TO PRECIPITATION FASTER THAN PREVIOUSLY INDICATED BY THE MODELS.
OBSERVATIONS IN NORTHWESTERN NEBRASKA INDICATED DEWPOINTS IN THE
LOWER 50S BEHIND THE FRONT.  MOISTURE WILL LIKELY BE SLIGHTLY HIGHER
WITH MORE RAINFALL AROUND THE OUR AREA...HOWEVER PERSISTENT
STRATIFORM RAIN BEHIND THE FRONT SEEMS UNLIKELY AT THIS POINT.
BROUGHT POPS OUT OF MOST OF THE AREA AFTER 18Z MONDAY...KEEPING ONLY
A SLIGHT CHANCE OF THUNDERSTORMS SOUTH OF INTERSTATE 35 FOR ANY
LINGERING CONVECTION.  DRIER AND COOLER AIR WILL HOLD OVER THE AREA
MONDAY...WITH MOSTLY CLOUDY SKIES DUE TO A PERSISTENT LAYER
ALTOSTRATUS ALOFT.  KEPT HIGHS IN THE MID 80S WITH COLD AIR
ADVECTION AND MOSTLY CLOUDY SKIES.

FOR MONDAY NIGHT INTO TUESDAY...IN THE WAKE OF THE SHORT WAVE
ACTIVITY...MODELS PUSHING SURFACE HIGH ACROSS THE AREA.  DEPENDING
ON PRECIPITATION COVERAGE TONIGHT...WITH DECREASING CLOUDS
NORTH MAY SEE SOME PATCHY FOG DEVELOP BY LATE NIGHT GENERALLY
FOR AREAS NORTH OF THE INTERSTATE...EXPECTING SOME INCREASE IN CLOUD
COVER OVER THE SOUTHERN PORTION OF CWA AGAIN BY LATE NIGHT WITH LOWS
MONDAY NIGHT FROM AROUND 60 NORTH TO MIDDLE 60S FAR SOUTH.  H850 MB
TEMPERATURES WARM A TAD WITH SOUTHEAST WINDS...WILL GO WITH HIGHS
MAINLY IN THE MORE SEASONAL UPPER 80S.

TUESDAY NIGHT INTO WEDNESDAY...CONTINUED WITH THE PREVIOUS THINKING
OF RETURN FLOW...WARM ADVECTION...ISENTROPIC LIFT ON THE BACK SIDE
OF THE RETREATING SURFACE HIGH.  ALOFT...MODELS NOW HINTING OF SOME
UPPER SUPPORT AS WELL WITH A SHORT WAVE COMING OUT OF THE
SOUTHWEST...HOWEVER GFS FOCUSING FURTHER SOUTH OF CWA AND NAM
GENERALLY ALONG AND NORTH OF I70.  GIVEN THE MODEL DISPARITY WENT
WITH SLIGHT CHANCES BUT DID CONTINUE INTO THE AFTERNOON HOURS OVER
ALL BUT THE SOUTHEAST CORNER COUNTIES GIVEN HINT OF UPPER SUPPORT.
HIGHS WEDNESDAY IN THE UPPER 80S TO LOWER 90S...IF CLOUD COVER LESS
THAN EXPECTED THEN WARMER READINGS WILL BE MORE IN STORE.

DILEMMA WITH WARM ADVECTION AND SHORTWAVE DIFFERENCES CONTINUE
WEDNESDAY NIGHT INTO THURSDAY NIGHT AND FOR NOW HAVE CONFINE POPS TO
AREAS GENERALLY NORTH OF I70 AND FOR THE OVERNIGHT HOURS.

GFS LOOKS A LITTLE OVERDONE ON ITS FRIDAY INTO FRIDAY NIGHT QPF
WHILE IT BUILDS HEIGHTS ALOFT.  ADDED SOME SLIGHT CHANCE POPS FOR
THE NORTHERN COUNTIES FRIDAY NIGHT AND SATURDAY WHERE THE ECMWF
HINTS OF SOME UPPER SUPPORT THERE AND FURTHER NORTH.  REST OF
FORECAST DRY AT THIS TIME.  HIGHS GENERALLY IN THE LOWER 90S NORTH
TO MIDDLE 90S SOUTH.
