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 Jun 16, 2:30 PM CST, 3 hours 44 minutes earlier.
AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE TOPEKA KS 330 PM CDT WED JUN 16 2004 .DISCUSSION... IT IS A COMPLICATED FORECAST FOR THE NEXT SEVERAL DAYS. THIS AFTERNOON A LINE OF THUNDERSTORMS HAS DEVELOPED OVER NORTHERN MISSOURI IN THE AXIS OF HIGHEST INSTABILITY AHEAD OF A COMPACT CONVECTIVELY INDUCED SHORTWAVE TRACKING THROUGH IOWA. A TRAILING COLD FRONT EXTENDING FROM CENTRAL IOWA THROUGH SOUTHEAST NEBRASKA INTO WESTERN KANSAS HAS INITIATED STORMS NEAR BEATRICE, NEBRASKA WITHIN THE LAST HOUR. I BELIEVE THAT SUBSIDENCE BEHIND THE VORTICITY MAX IN IOWA WILL LIMIT CONVECTION SOMEWHAT THIS AFTERNOON, BUT IVE INSERTED A 50 PERCENT CHANCE OF STORMS ALONG THE NEBRASKA BORDER FOR THE PEAK HEATING HOURS. THIS FRONT WILL SLOWLY DROP SOUTH THIS EVENING. WITH LITTLE DEEP LAYER SHEAR, THESE STORMS SHOULD BE DIURNALLY DRIVEN AND COLLAPSE BY MID EVENING. WITH THE SLOW MOVEMENT OF THESE STORMS LOCALLY EXCESSIVE RAIN IS POSSIBLE EARLY THIS EVENING NORTH OF INTERSTATE 70. LOOKING FURTHER WEST SOUTHEASTERLY UPSLOPE FLOW INTO WESTERN KANSAS AND EASTERN COLORADO WILL LIKELY GENERATE A LARGE CLUSTER OF STORMS THIS EVENING. THE ETA AND GFS SUGGEST THE DEVELOPMENT OF A LOW LEVEL JET THAT SHOULD KEEP STORMS GOING THROUGH THE NIGHT AS THIS ANTICIPATED COMPLEX MOVES INTO CENTRAL KANSAS. HEAVY RAIN WILL ALSO BE A CONCERN WITH THIS COMPLEX GIVEN THE SLOW MOVEMENT AND RICH MOISTURE AVAILABLE FOR EFFICIENT PRECIPITATION GENERATION. THEREFORE I HAVE EXPANDED THE FLOOD WATCH TO INCLUDE THE ENTIRE FORECAST AREA THROUGH NOON TOMORROW. I HAVE THE LEAST CONFIDENCE THAT FLASH FLOOD GUIDANCE WILL BE REACHED EAST OF EMPORIA TONIGHT, BUT REMNANTS OF TONIGHTS MCS MAY PERPETUATE INTO EASTERN KANSAS TOMORROW MORNING. A SIMILAR SETUP IS ON TAP FOR TOMORROW NIGHT. BOTH THE ETA AND GFS ADVERTISE A WEAK SURFACE LOW OVER SOUTHERN KANSAS AND THE DEVELOPMENT OF A LOW LEVEL JET TOMORROW NIGHT. TOMORROW EVENINGS MCS COULD INITIATE A BIT FURTHER SOUTH AND EAST THAN TONIGHTS, BUT WELL HAVE TO MONITOR THE MESOSCALE EVOLUTION OF TONIGHTS SYSTEM TO SEE WHERE OUTFLOW BOUNDARIES SET UP TOMORROW.
