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. && .TOP WATCHES/WARNINGS/ADVISORIES...NONE. && DC/PF
