What happened

The episode as NWS EAX wrote it up.

A very strong upper level storm system tracked from southern Oklahoma into southeast Missouri November 30th through December 1st. Moisture from the Gulf of Mexico streamed into the region over a cold air mass. Accumulating snow was noted south of Kansas City to Kirksville line. Areas north of that line had only trace amounts or no snow at all. Along and south of that line heavy snows were observed. 3 to 6 inches of snow was found from around Kansas city extending northeast to Kirksville. A band of 6 to 10 inches of snow prevailed from Lee's Summit and Pleasant Hill northeast through Higginsville and Macon. 10 to 16 inches of snow was common from Butler to Harrisonville, extending northeast through Clinton, Warrensburg, Sedalia, Boonville, and Moberly. Butler and Clinton both came in with new daily snowfall records at 18 inches. Moberly also set a one day snowfall record of 15 inches. Travel was extremely dangerous and Interstate 70 had to be closed for a time. The snows ended early on December 1st.

AREA FORECAST DISCUSSION

515 PM CST THU NOV 30 2006

.DISCUSSION...

...HEAVY SNOW WARNING FOR MUCH OF THE FORECAST AREA FROM KANSAS
CITY NORTHEAST TO KIRKSVILLE AND POINTS SOUTH THROUGH 6 AM FRIDAY...

MAIN FORECAST CONCERN IS THE WINTER STORM FOR THE OVERNIGHT HOURS.
THE UPPER LEVEL LOW IS NOW MOVED INTO SOUTH CENTRAL OKLAHOMA. WATER
VAPOR IMAGERY SHOWS AN EXTENSIVE SHIELD OF MOISTURE IN THE
NORTHEASTERN QUADRANT OF THE UPPER LEVEL STORM. THIS IS BACKED UP
WITH REGIONAL RADAR IMAGES THAT SHOW A FAIR AMOUNT OF MOISTURE
SURGING NORTH FROM ARKANSAS INTO SOUTHERN MISSOURI. NORTHEAST OF THE
UPPER LEVEL LOW...ACROSS EAST CENTRAL KANSAS AND WEST CENTRAL
MISSOURI...INFRARED IMAGERY SHOWS A FAIR AMOUNT OF ENHANCEMENT ALOFT
IN A DIFFLUENT AREA WELL NORTH NORTHEAST OF THE UPPER LEVEL LOW. IN
THIS AREA A NICE BAND OF MODERATE TO HEAVY SNOW HAS BEGUN TO
FALL...AFFECTING LOCATIONS FROM KANSAS CITY SOUTH ALONG THE STATE
LINE. HAVE UPPED THE SNOW FALL TOTALS FROM KANSAS CITY SOUTH TO
REFLECT THIS TREND.

12Z MODEL RUNS CONTINUED TO KEEP NEARLY THE SAME TRACK AND TREND AS
PREVIOUS RUNS...LIFTING THE UPPER LEVEL LOW THROUGH SOUTH CENTRAL
MISSOURI DURING THE OVERNIGHT HOURS. THE 18Z MODELS HAVE ARE NOT
SHIFTING MUCH EITHER. THE NAM HAS ALSO MAINTAINED ITS SLIGHTLY
SLOWER TREND IN THE EASTWARD PROGRESS OF THE UPPER LEVEL LOW. MODEL
PREFERENCE IS TOWARDS THE NAM...BUT ONLY SLIGHTLY AS THE 18Z SNOW
ACCUMULATIONS ARE A LITTLE LOW ACROSS THE NORTHERN SIDE FROM KANSAS
CITY TO KIRKSVILLE. SOUTHEAST SIDE OF THE FORECAST AREA...FROM
BUTLER TO MOBERLY...IS STILL LOOKING GOOD TO RECEIVE OVER A FOOT OF
SNOW. CROSS SECTIONS INDICATE PERIODS OF CONVECTIVE ACTIVITY CAN NOT
BE RULED OUT AS INSTABILITY WILL BE PRESENT AT AND ABOVE OUR BEST
FRONTOGENESIS REGIONS. BASICALLY...ALL THE INGREDIENTS FOR HEAVY
SNOW ARE IN PLACE ACROSS THE SOUTHEAST HALF OF THE FORECAST AREA.
HOWEVER...A STEEP GRADIENT IN THE SNOW ACCUMULATION IS STILL
EXPECTED IN AN AREA FROM LEAVENWORTH TO OLATHE NORTHEAST THROUGH
KIRKSVILLE AND MACON. IN SHORT...OUR HEAVY SNOW WARNING AND WINTER
STORM WARNING LOOK GOOD...WITH ONLY MINOR ADJUSTMENTS TO SNOW TOTALS
BEING MADE.

SNOW IS STILL ON TRACK TO MOVE OUT OF MUCH OF THE FORECAST AREA BY 6
AM FRIDAY...THOUGH A FEW NON-ACCUMULATING SNOW SHOWERS MIGHT LINGER
THROUGH MID-MORNING IN NORTHEAST MISSOURI.

CUTTER

EXTENDED DISCUSSION...

NOT MUCH CHANGE MADE TO THE EXTENDED FORECAST WITH ONGOING WINTER
STORM. MAIN CONCERN WILL AGAIN BE TEMPERATURES THROUGH THE WEEKEND
AND INTO THE BEGINNING OF NEXT WEEK. THE TRACK OF THE UPPER SYSTEM
DURING THE NEXT 24 HOURS AND RESULTING SNOW SWATH WILL ULTIMATELY
HAVE A BIG IMPACT ON GOING TEMPS THEREAFTER. LOCATIONS WITHIN THIS
SNOW SWATH WILL LIKELY STRUGGLE TO REACH THE 30 DEGREE MARK FOR
AFTERNOON HIGHS WITH OVERNIGHT LOWS POSSIBLY DIPPING INTO THE SINGLE
DIGITS. IN ADDITION...AREAWIDE TEMPS WILL HOVER AROUND OR JUST
ABOVE THE FREEZING MARK ALLOWING THE SNOW PACK TO STICK AROUND FOR
SEVERAL DAYS. THEREFORE...GENERALLY WENT BELOW GUIDANCE NUMBERS
THROUGH THE WEEKEND WITH BEST GUESS TO SNOW PACK SWATH AND
SUBSEQUENT IMPACTS.

SECONDARY SHORT WAVE PUSHES ACROSS THE MIDWEST REGION LATE IN THE
WEEKEND BRINGING ANOTHER SURGE OF ARCTIC AIR FOR THE BEGINNING OF
THE WEEK. NOT MUCH MOISTURE ASSOCIATED WITH THIS SYSTEM SO
MAINTAINED A DRY FORECAST. NORTHWEST FLOW ALOFT PREVAILS INTO
MIDWEEK WITH ONLY MINOR RIPPLES IN THE FLOW BRINGING INTERMITTENT
HIGH CLOUDINESS. MODELS THEN BRING THE NEXT SHORT WAVE THROUGH THE
REGION FOR MIDWEEK WITH ANOTHER ROUND OF COLDER AIR FILTERING SOUTH.
WITH INCREASING MODEL DISCREPANCY AND LITTLE AVAILABLE MOISTURE
ACROSS THE REGION...WILL CONTINUE WITH THE DRY FORECAST THROUGH THE
REMAINDER OF THE FORECAST PERIOD.

DEROCHE

.PREV DISCUSSION...

/1236 PM CST THU NOV 30 2006/
QUICK ADJUSTMENT TO THE AFTERNOON FORECAST FOR TEMPERATURES. OUR DRY
NORTH WINDS ARE DOING AN EXCEPTIONALLY GOOD JOB OF KEEPING
TEMPERATURES QUIT COLD. HAVE LOWERED AFTERNOON HIGHS TO REFLECT
FALLING TEMPERATURES IN CENTRAL MISSOURI...AND TO FLATLINED
TEMPERATURES ACROSS THE REST OF THE FORECAST AREA.

AS FOR OUR PRECIPITATION...NOT MUCH HAS CHANGED. LATE MORNING RADAR
IMAGES AND SURFACE REPORTS INDICATED A SMALL AREA OF FREEZING RAIN
AND SLEET WAS TRYING TO WORM ITS WAY NORTH ACROSS THE FAR
SOUTHWESTERN CORNER OF THE FORECAST AREA. HOWEVER...BY NOON RADAR
SIGNATURE INDICATED THAT THE CONVECTIVE ELEMENT HAD GLACIATED AND
WAS DISSIPATING. FLAKES ARE STARTING TO FALL ACROSS EAST CENTRAL
KANSAS AND WEST CENTRAL MISSOURI ON SOUTH...BUT HEAVY SNOW
ACCUMULATION IS STILL NOT ANTICIPATED UNTIL THE EVENING HOURS.

CUTTER

/442 AM CST THU NOV 30 2006/
A RECORD BREAKING WINTER STORM IS LIKELY ACROSS PARTS OF THE CWA
TODAY AND TONIGHT. AN ILL DEFINED UPPER LOW WAS LOCATED IN CENTRAL
NEW MEXICO WITH A STRONG SHORTWAVE IN SOUTHERN NEW MEXICO. AT THE
SURFACE...THE SHALLOW ARCTIC AIR MASS HAS PRESSED SOUTH INTO NORTHERN
ARKANSAS AND NORTHERN TEXAS WITH THE BOUNDARY BECOMING STATIONARY IN
SOUTHWESTERN ARKANSAS. THIS APPEARS TO BE THE LOCATION OF THE FUTURE
SURFACE LOW DEVELOPMENT ADVERTISED BY THE NAM/GFS. A SHALLOW VERY DRY
AND COLD AIR MASS HAS SURGED THROUGH THE CWA. HOWEVER...COPIOUS
MOISTURE WILL SURGE NORTH ABOVE THE SHALLOW SURFACE AIR
MASS...PROVIDING SUFFICIENT MOISTURE FOR A HEAVY PRECIPITATION EVENT.

THE MOST CRITICAL FACTOR WILL BE THE EXACT TRACK OF THE UPPER STORM
SYSTEM THE NEXT 24 HOURS. THE GFS/NAM ARE SIMILAR IN TRACKING THE
UPPER LEVEL LOW IN SOUTHERN MISSOURI TONIGHT...PUTTING THE
SOUTHEASTERN ONE HALF OF THE CWA IN FAVORABLE ZONE FOR HEAVY
SNOWFALL. THE INTENSITY OF THE MODELS LOOK REASONABLE AS STRONG
CYCLOGENESIS FROM H8 TO H7 AS THE UPPER STORM SYSTEM APPROACHES
STRONG BAROCLINICITY.

CANNOT ARGUE WITH THE CURRENT TRACK SUGGESTED BY THE MODELS BUT ANY
DEVIATION OF THE TRACK WILL HAVE A SIGNIFICANT IMPACT ON SNOW
AMOUNTS. THE ONLY DISCREPANCY BETWEEN THE GFS AND NAM IS THE SPEED OF
THE GFS. THE GFS LOOKS A LITTLE QUICK TONIGHT IN THE MOVEMENT ACROSS
MISSOURI GIVEN THE STORM IS STILL RATHER BURIED IN THE SOUTHERN
BRANCH.

OTHERWISE...TOUGH TO FIND ANY FORCING FUNCTION MISSING WITH THIS
EVENT. NAM DEPICTS A DEEP MID LEVEL TROWAL DEVELOPING TONIGHT...FROM
JUST NORTH OF MKC TO IRK. VERY STRONG H7-H3 LAYER DIVERGENCE-Q ALSO
NOTED TONIGHT SOUTH OF A MKC-IRK LINE WITH MODERATE TO STRONG
ISENTROPIC LIFT ALSO PRESENT...ESPECIALLY FOR THE EAST CENTRAL
PORTION OF THE CWA. MID LEVEL FRONTOGENETICAL FORCING IS ALSO RATHER
STRONG...ALTHOUGH INSTABILITY ABOVE THE FRONTOGENETICAL LAYERS ARE
RATHER STABLE. REGARDLESS...STRONG UVV IN THE DENDRITIC
LAYER...ALONG WITH THE STRONG FORCING...WILL YIELD HEAVY SNOW
AMOUNTS. MODEL QPF DOES NOT LOOK TOO UNREASONABLE. SNOWFALL AMOUNTS
MAY BE A LITTLE HEAVIER THAN CURRENTLY FORECASTED IN SOME AREAS AS
MESOSCALE FORCING ALONG WITH HIGHER THAN NORMAL SNOWFALL RATIOS ARE
LIKELY. THE HEAVIEST SNOWFALL IS PROJECTED TO BE IN THE EAST CENTRAL
PORTION OF THE CWA.

SNOW TO END BY DAYBREAK. GIVEN PROJECTED SNOW COVER...HAVE WENT LOWER
THAN GUIDANCE.

THERE WILL BE A VERY STRONG GRADIENT OF SNOWFALL AMOUNTS ON THE
NORTHERN PERIPHERY OF THIS STORM. AS A RESULT...ANY SMALL DEVIATION
IN STORM TRACK WILL AFFECT SNOWFALL ACCUMULATIONS SIGNIFICANTLY.

.DAYS TWO THROUGH SEVEN...FRIDAY THROUGH WEDNESDAY

NO HAZARDOUS WEATHER IS EXPECTED AT THIS TIME.
