The episode as NWS TOP wrote it up.
A winter storm system brought a round of freezing rain and drizzle to locations mainly north of Interstate 35 early the morning of December 1st. Around one quarter of an inch of ice accumulated in portions of north central Kansas, before near surface temperatures rose above freezing after sunrise.

NWS Topeka, KS wrote its last area forecast discussion before the first event at Nov 30, 8:55 PM CST, 4 hours 5 minutes earlier.
AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE TOPEKA KS 855 PM CST FRI NOV 30 2007 .DISCUSSION... CONCERN WITH POTENTIAL ICE STORM CONTINUES TO BE SFC TEMPS. EXCEPT FOR FAR SOUTHERN PORTIONS OF THE FORECAST AREA...TEMPS HAVE FALLEN BELOW FREEZING WITH DRY AIR /DEWPOINTS IN THE SINGLE DIGITS/ CONTINUING TO ADVECT IN FROM THE EAST. WITH AN AC DECK MOVING IN NOW...DO NOT ANTICIPATE TEMPS WILL DROP OFF AS THEY HAVE PREVIOUS NIGHTS...AND SHOULD STAY RELATIVELY STEADY OR FALL ONLY A COUPLE DEGREES THROUGH THE REST OF THE NIGHT. WITH THE DRY AIR ADVECTION...HAVE PUSHED BACK THE ONSET OF PRECIP ACROSS THE FORECAST AREA UNTIL AFTER MIDNIGHT. THINK THE PRECIP WILL ACTUALLY BEGIN FALLING AROUND 09Z AS MOISTURE ADVECTION AND LIFT GET STRONG ENOUGH TO OVERCOME THE DRY AIR AT THE SFC. 00Z SOUNDINGS FROM THE NAM AND RUC SHOW THE MOST LIKELY AREA FOR SIGNIFICANT ICE ACCUMULATIONS TO BE ACROSS THE NORTH WERE SFC TEMPS WILL BE BELOW FREEZING LONGER. STRONG MOISTURE ADVECTION FROM THE SOUTH AROUND 12Z WILL FORCE TEMPS TO SLOWLY CLIMB THROUGH THE MID MORNING HOURS. WITH LESS TIME FOR FZRA ALONG AND SOUTH OF I-70...ANTICIPATE ACCUMULATIONS TO BE BELOW A QUARTER OF AN INCH WITH TEMPS WARMING ABOVE FREEZING ALONG THE I-70 CORRIDOR BETWEEN 13 AND 15Z. WITH THIS IN MIND...CURRENT HAZARDS SEEM TO BE IN PRETTY GOOD SHAPE AND WILL NOT MAKE ANY ADJUSTMENTS TO THE ADVISORY OR WARNING. THE ONE THING TO LOOK OUT FOR WOULD BE IF PRECIP STARTED MUCH BEFORE 09Z. THEN THE WINDOW FOR FZRA WOULD BE A LITTLE LARGER AND ACCUMULATIONS COULD BE HIGHER FURTHER SOUTH. && WOLTERS .PREV DISCUSSION /336 PM CST/... MAIN CONCERN FOR THIS FORECAST CENTERS ON THE IMPENDING STORM SYSTEM TONIGHT THROUGH SATURDAY. WATER VAPOR SATELLITE SHOWS UPPER LOW OFF THE CA COAST BEING ABSORBED BY THE DIGGING TROUGH IN THE EASTERN PACIFIC. SUB TROPICAL MOISTURE WAS STREAMING NORTHEAST AHEAD OF THIS SYSTEM ACROSS THE FOUR CORNERS AND SOUTHWEST TEXAS. A COLD FRONT MOVED THROUGH THIS MORNING AND WAS LOCATED OVER OKLAHOMA THIS AFTERNOON. TEMPERATURES WERE RUNNING COOLER THAN GUIDANCE THIS AFTERNOON AROUND 4 DEGREES OR SO. DEW POINTS IN THE SINGLE DIGITS WERE ACROSS MUCH OF KANSAS...MISSOURI AND NEBRASKA. MAIN CONCERN FOR THIS EVENING WITH PATCHES OF CIRRUS THROUGH MID EVENING COULD SEE TEMPERATURES DROP INTO THE MIDDLE 20S NORTH OF INTERSTATE 70 AND BELOW FREEZING SOUTHEAST OF INTERSTATE 35. MODELS HAVE BEEN RUNNING TOO WARM AND ARE VIGOROUS IN SCOURING OUT THE LOW LEVEL COLD AIR. 18Z NAM HAS COME IN A BIT COOLER THAN THE 12Z RUN...THE GFS CONTINUES TO BE TOO WARM IN THE LOW LEVELS. GOOD ISENTROPIC LIFT/WARM AIR ADVECTION PATTERN SETS UP THIS EVENING AS THE LOW LEVEL JET INCREASES TO NEAR 50 KTS BY 06Z AND CONTINUES THROUGH THE NIGHT WITH 50 TO 60 KTS AT 850 MB. WITH THE SUBTROPICAL MOISTURE PLUME TO THE SOUTH CONDENSATION PRESSURE DEFICITS SHRINK RELATIVELY QUICKLY THIS EVENING REACHING SATURATION NEAR OR SHORTLY AFTER MIDNIGHT. SURFACE WINDS WILL INCREASE TO AROUND 20 KTS WITH HIGHER GUSTS CREATING A HAZARDOUS SITUATION. THIS PATTERN WILL CONTINUE THROUGH THE MID TO LATE MORNING HOURS ESPECIALLY NEAR THE NEBRASKA BORDER SO HAVE EXTENDED THE ICE STORM WARNING TO END AT NOON. TEMPERATURES WILL BE SLOW TO RECOVER NEAR THE BORDER. INCREASED THE AMOUNT OF ICING NEAR THE BORDER TO BE BETWEEN A QUARTER AND A HALF INCH. FURTHER SOUTH IN THE ADVISORY AREA LOOKING AT AMOUNTS AROUND TWO TENTHS OF AN INCH OR LESS. THE RETURN OF WARM AIR AT THE SURFACE BEHIND THE WARM FRONT WILL BE KEY TO THE ICE AMOUNTS SOUTH OF HIGHWAY 56. CURRENTLY THINKING AMOUNTS THERE WILL BE AROUND A TENTH OF AN INCH OR SO. TEMPERATURES STILL LOOK LIKE THEY WILL RISE BEHIND THE WARM FRONT TO WELL ABOVE FREEZING AND MELT THE ICE ALONG WITH A GOOD SOAKING RAIN. INCREASED QPF SATURDAY MORNING ALONG THE LINES OF HPC WITH SOME TWEAKS. THE MOISTURE EXITS THE AREA DURING THE AFTERNOON HOURS WITH THE BEST LIFT ACROSS THE FAR NORTHEAST COUNTIES INTO CENTRAL IOWA. SOME LIGHT RAIN IS STILL POSSIBLE SATURDAY NIGHT INTO EARLY SUNDAY AHEAD OF AN APPROACHING MID LEVEL TROUGH AND SURFACE COLD FRONT. THE UPPER TROUGH MOVES EAST OF THE CWA AROUND MID DAY SUNDAY ENDING PRECIPITATION. LOW LEVEL THICKNESS WOULD SUGGEST THAT SOME SNOW MAY MIX WITH THE RAIN LATE SATURDAY NIGHT AND SUNDAY MORNING BEFORE ENDING. HIGHS ON SUNDAY WILL BE ONLY IN THE 30S TO LOWER 40S. NORTHWEST FLOW SHOULD RULE MUCH OF NEXT WEEK WHICH MAKES TEMPERATURE FORECASTS TRICKY. APPEARS WARM AIR ADVECTION WILL BRING TEMPS UP ABOVE NORMAL FOR TUESDAY AND LIKELY WEDNESDAY WITH COOLER AIR ENTERING PERHAPS LATE WEDNESDAY FOR A COOLER END OF THE FORECAST. HAVE INCREASED TEMPS EARLY AND DECREASED THEM LATE WITH THIS IN MIND...BUT CAN ENVISION ACTUAL TEMPS MORE EXTREME THAN CURRENTLY FORECAST. PRECIPITATION CHANCES APPEAR RATHER LOW IN THIS REGIME WITH SOME LIGHT ACCUMULATIONS POSSIBLE WITH A SHORTWAVE AROUND WEDNESDAY NIGHT BUT WILL KEEP THINGS DRY FOR THE TIME BEING. THERE ARE INDICATIONS OF A CHANGE IN THE UPPER FLOW PATTERN AROUND FRIDAY WHICH MAY BRING MORE SIGNIFICANT PRECIPITATION CHANCES THEN...BUT AGAIN CONFIDENCE IS TOO LOW TO JUMP ON ANYTHING. && .AVIATION... CONDITIONS TO RAPIDLY WORSEN OVERNIGHT. APPEARS PRECIP WILL BEGIN IN THE 6Z-9Z TIME FRAME WITH CEILINGS DROPPING TO AT LEAST IFR DURING PEAK INTENSITY TIME...LIKELY FROM 9Z TO 15Z. TEMPS EXPECTED TO BE BELOW FREEZING NEAR THE GROUND BUT NOT FAR ABOVE SO FZRA IS EXPECTED. SOME IMPROVEMENT IS LIKELY BY LATE IN THE 18Z CYCLE. && .TOP WATCHES/WARNINGS/ADVISORIES... ICE STORM WARNING IN EFFECT FROM 06Z SATURDAY THROUGH 18Z SATURDAY PORTIONS OF NORTH CENTRAL AND NORTHEAST KANSAS...KSZ008>012-020>024. FREEZING RAIN ADVISORY IN EFFECT FROM ALONG THE INTERSTATE 70 CORRIDOR TO NEAR INTERSTATE 35 FROM 06Z SATURDAY THROUGH 15Z SATURDAY...KSZ034>040-054>056. &&
