$$What forecasters said that day
The local office's own words before this severe thunderstorm warning went out, 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 this severe thunderstorm warning went out at May 12, 3:46 AM CDT, 10 hours 58 minutes earlier.
Area forecast discussion, May 12, 3:46 AM CDT, 10 hours 58 minutes before
AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE TOPEKA KS 346 AM CDT THU MAY 12 2005 .DISCUSSION... HAVE FOCUSED ON THE SHORT TERM WITH THE MAIN CONCERN BEING THE FRONTAL POSITION AND PRECIP AMOUNTS. MODELS ARE SHOWING A BETTER CONSENSUS IN THE POSITION AND TIMING OF THE FRONTAL BOUNDARY THIS MORNING...WHICH IS SLOWING MOVING EAST ACROSS WESTERN KS AT 08Z. THIS BOUNDARY IS EXPECTED TO STALL ACROSS CENTRAL KS TODAY AND MOVE VERY LITTLE THROUGH TONIGHT. ADDITIONALLY AN UPPER LEVEL JET MAX WILL MOVE ACROSS WESTERN KS AS A SHORTWAVE EJECTS FROM THE BASE OF THE CLOSED LOW. THIS WILL PLACE THE FORECAST AREA UNDER THE RIGHT ENTRANCE REGION OF THIS JET STREAK AIDING IN UPPER LEVEL DIFFLUENCE AND VERTICAL MOTION. WITH THE LOW LEVEL JET SUSTAINING MOISTURE CONVERGENCE ALONG THIS BOUNDARY TONIGHT AND PWS POOLING AROUND 1.5 INCHES...HEAVY RAINS ARE POSSIBLE THIS EVENING. AGREE WITH HPC/S EXCESSIVE RAINFALL DISCUSSION AND HAVE DECIDED TO ISSUE A FLOOD WATCH BEGINNING THIS AFTERNOON AND CONTINUING OVERNIGHT. THE MAIN CONCERN IS FOR CONVECTION TO TRAIN OVER THE SAME AREAS WERE RAINFALL AMOUNTS COULD EXCEED 2 INCHES. HAVE FOLLOWED PRETTY CLOSELY WITH HPC/S QPF FORECAST WHICH HAS AN AXIS OF RAINFALL ACROSS THE CENTER OF THE FORECAST AREA OF 2 TO 3.25 INCHES BY FRIDAY EVENING. AS FOR SEVERE WEATHER...MODELS INDICATE THAT IF WE ARE ABLE TO WARM UP THERE SHOULD BE ENOUGH INSTABILITY AND DEEP LAYER SHEAR FOR SOME STORMS TO PRODUCE LARGE HAIL. THINK THAT THE BEST AREA FOR THE INSTABILITY TO BE REALIZED SHOULD BE ACROSS EAST CENTRAL KS. THERE SHOULD BE MORE SUNSHINE OVER EAST CENTRAL KS TODAY. HOWEVER THINK THE BOUNDARY SHOULD STAY MAINLY WEST OF THE AREA. THE TORNADO THREAT DOES NOT LOOK AS HIGH FOR TODAY. SURFACE WINDS ARE NOT EXPECTED TO BE AS BACKED AS THEY WERE ACROSS THE NORTHERN COUNTIES YESTERDAY. THAT DOES NOT MEAN THAT LOCAL STORM SCALE FEATURES MAY ENHANCE LOW LEVEL WINDS. TEMPERATURES FROM THE PREVIOUS FORECAST SEEM PRETTY REASONABLE. DID ADJUST TEMPS DOWN FOR FRIDAY AND SATURDAY. ON FRIDAY THINK CLOUDY SKIES AND RAINFALL WILL PREVENT HIGHS FROM WARMING UP TO MUCH AND HELD HIGHS IN THE MID 60S FOR MOST AREAS. ADDITIONALLY CAA SHOULD BE ON THE INCREASE DURING THE DAY AS THE FRONT MOVES SOUTH. WITH THINGS CLEARING OUT FRIDAY NIGHT AND SURFACE RIDGING OVER THE AREA SATURDAY...LOWERED MIN TEMPS INTO THE MID 40S. DID NOT MAKE ANY CHANGES TO THE FORECAST BEYOND SATURDAY. && .TOP WATCHES/WARNINGS/ADVISORIES... FLOOD WATCH FOR ALL COUNTIES THIS AFTERNOON AND TONIGHT. WOLTERS
