The local office's own words before the first event, as it sent them, from the Iowa Environmental Mesonet's archive of National Weather Service text.
NWS Topeka, KS wrote its last area forecast discussion before the first event at Aug 31, 2:46 PM CST, 2 hours 33 minutes earlier.
AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE TOPEKA KS 346 PM CDT TUE AUG 31 2010 .DISCUSSION... TONIGHT THROUGH THURSDAY AFTERNOON... WATER VAPOR IMAGERY INDICATES A BROAD UPPER LEVEL LOW OVER THE WESTERN CONUS. FETCH OF DEEPER MOISTURE MAKING ITS WAY NORTHWARD THROUGH THE SOUTHERN PLAINS. DEWPOINTS THROUGHOUT THE AREA HAVE CREPT INTO THE LOWER TO MID 70S. AS THE DEEPER MOISTURE MAKES ITS WAY INTO NORTHEASTERN KANSAS PRECIPITABLE WATER VALUES WILL REACH NEAR 2 INCHES. PRECIPITATION CHANCES WILL BE RELEGATED TO THE LATE EVENING TO OVERNIGHT HOURS AS A COLD FRONT CURRENTLY LOCATED ON A LINE FROM OMAHA TO SMITH CENTER TO HAYS WILL PUSH SOUTHWARD INTO NORTH CENTRAL KANSAS. STRONG CONVERGENCE ALONG THE FRONT IN CONJUNCTION WITH MU CAPES AROUND 1500 TO 2000 J/KG WILL ALLOW FOR THUNDERSTORM FORMATION ALONG AND WEST OF A FALLS CITY TO MANHATTAN TO SALINA LINE. MOISTENING IN THE MID LEVELS INDICATED BY AN INVERTED V SOUNDING AND LOW LEVEL WIND SHEAR VALUES AROUND 20 TO 25 KTS INDICATE THE POTENTIAL FOR DOWNDRAFT WINDS WITH THE STRONGEST STORMS OVERNIGHT. DEEP LAYER SHEAR OF AROUND 20 TO 30 KNOTS WILL BE SUFFICIENT FOR SUSTAINED STRONG TO SEVERE STORMS...BUT IS NOT SUFFICIENT TO WARRANT CONCERN FOR LARGE HAIL. THE PRIMARY THREAT FOR OVERNIGHT CONVECTIVE ACTIVITY WILL BE HEAVY RAIN...WITH ISOLATED FLOODING POTENTIAL AND BRIEF GUSTY WINDS. BOUNDARY THEN WASHES OUT AND BECOMES QUASI-STATIONARY THROUGHOUT WEDNESDAY. CONFIDENCE FOR CONVECTIVE POTENTIAL IS RATHER LOW...HOWEVER WITH THE BOUNDARY LINGERING IN THE AREA CONVECTION IS POSSIBLE ALONG THE STRONGER AREAS OF CONVERGENCE. ONCE AGAIN SEVERE POTENTIAL SHOULD BE RELEGATED TO THE AFTERNOON HOURS AFTER THE SURFACE HAS HAD AMPLE TIME TO HEAT. MODELS CURRENTLY SUGGEST THE BOUNDARY WILL SET UP ALONG OR JUST NORTH OF INTERSTATE 70...SO CONVECTIVE DEVELOPMENT SHOULD BE CONFINED TO AREAS NORTH OF INTERSTATE 70. SHEAR PARAMETERS CONTINUE TO LOOK AMPLE FOR SUSTAINED STRONG/SEVERE AFTERNOON STORMS. PRECIPITABLE WATER DOES NOT LOOK QUITE AS IMPRESSIVE...HOWEVER TRAINING CELLS COULD BRING ANOTHER ROUND OF FLASH FLOODING POSSIBILITIES. FOR THURSDAY AND SURFACE BOUNDARY WILL PUSH THROUGH THE AREA...BRINGING ONE FINAL ROUND OF THUNDERSTORMS...MAINLY ALONG AND SOUTH OF INTERSTATE 70. THE STRONGEST STORMS SHOULD FORM ALONG AND SOUTH OF THE BOUNDARY AS DAYTIME HEATING WILL BE NEEDED TO GET ENOUGH INSTABILITY FOR STRONG STORMS. EXPECT THESE STRONG STORMS TO FORM ALONG AND SOUTH/SOUTHEAST OF INTERSTATE 35. COOLER TEMPERATURES ARE EXPECTED BEHIND THE SURGE OF COOL AIR. JL FOR THURSDAY NIGHT AND FRIDAY...FRONT AND ASSOCIATED CONVECTION SHOULD BE LEAVING EC KS THURSDAY EVENING AND HAVE LEFT SLIGHT CHC POPS IN THAT AREA UNTIL MIDNIGHT. AFTER THAT...SUBSIDENCE BEHIND DEPARTING TROUGH SHOULD CLEAR SKIES OUT AND DRY OUT THE BOUNDARY LAYER...LEADING TO A PLEASANT DAY ON FRIDAY WITH HIGHS IN THE UPPER 70S TO LOWER 80S AND DEWPOINTS IN THE 50S. SATURDAY AND THROUGH MONDAY NIGHT...MADE LITTLE CHANGE TO PREVIOUS FORECAST. LARGE H5 RIDGE TO DOMINATE MUCH OF THE SOUTHERN HALF OF THE NATION THROUGH THE LABOR DAY WEEKEND. SFC HIGH TO PUSH RAPIDLY EAST SATURDAY AFTERNOON ALLOWING WAA TO RETURN ALONG WITH A GRADUAL INCREASE IN TEMPERATURES THROUGH THE WEEKEND. LEFT HIGHS IN THE MID TO UPPER 80S...AND LOWS IN THE UPPER 50S ON SATURDAY THEN INCREASING INTO THE 60S BY SUNDAY EVENING. TUESDAY...SHRTWV TROUGH MOVING ACROSS THE NORTHERN U.S. WILL PUSH H5 RIDGE TO THE EAST...WHILE A SFC LOW DEVELOPS OVER THE DAKOTAS MONDAY MORNING. 00Z ECMWF AND 6 AND 12Z GFS VARY SIGNIFICANTLY ON THE THE POSITION OF A FRONTAL BOUNDARY ASSOCIATED WITH THE CLOSED LOW. GFS HAS BEEN CONSISTENT WITH TWO RUNS IN REGARDS TO MOVING THE FRONT THROUGH NORTHEAST KANSAS AND GENERATING PRECIP. ECMWF KEEPS FRONT TO THE NORTH AS SECONDARY SFC LOW DEVELOPS OVER WESTERN KANSAS. INTRODUCED SLIGHT POPS INTO EXTREME EASTERN KANSAS FOR TUESDAY...BUT WILL HAVE TO WAIT FOR MORE CONSISTENT SOLUTIONS TO BUMP UP ANY PRECIP WORDING. BYRNE && .AVIATION... SHOWERS AND THUNDERSTORMS EXPECTED TO FORM NEAR THE TERMINALS LATER THIS AFTERNOON. AFTERNOON SHOWERS SHOULD REMAIN MOSTLY ISOLATED OR SCATTERED...SO CB GROUP SHOULD COVER THREAT FOR THIS AFTERNOON. BEST CHANCE FOR SHOWERS AND THUNDERSTORMS OVERNIGHT WILL BE AT KMHK AS THE SURFACE BOUNDARY SLIPS SOUTHWARD. CONVECTION CHANCES FURTHER EAST ARE MORE UNCERTAIN...SO KEPT KTOP AND KFOE VCTS FOR NOW. BOUNDARY WILL RETREAT WEDNESDAY MORNING BUT SCATTERED CONVECTION WILL BE POSSIBLE THROUGH THE REMAINDER OF THE TAF PERIOD. JL && .TOP WATCHES/WARNINGS/ADVISORIES...NONE. && 99/99
