What happened

The episode as NWS SGF wrote it up.

A fast moving storm system brought several forms of precipitation to extreme southeast Kansas and the Missouri Ozarks. The combination of rain, freezing rain, sleet, and snow were observed in numerous counties. For areas along and north of a line from McCune, Kansas to Eldon, Missouri, mainly snow fell with accumulations ranging from five to seven inches. Elsewhere, sleet and freezing rain accumulations ranged from one quarter of an inch to around an inch.

What forecasters said that day

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 Springfield, MO wrote its last area forecast discussion before the first event at Jan 20, 5:49 PM CST, 1 hour 11 minutes earlier.

AREA FORECAST DISCUSSION...AVIATION UPDATE.
NATIONAL WEATHER SERVICE SPRINGFIELD MO
549 PM CST SAT JAN 20 2007

...SIGNIFICANT SNOW AND SLEET ACCUMULATIONS TONIGHT...

.DISCUSSION...

SNOW HAD SPREAD NORTHEAST ACROSS SOUTHEAST KANSAS AND MUCH OF THE
MISSOURI OZARKS SATURDAY AFTERNOON. THE SNOW HAS BEEN MIXED WITH
SLEET AT THE ONSET OF THE PRECIPITATION ESPECIALLY NEAR THE ARKANSAS
BORDER. THE UPPER LOW RESPONSIBLE FOR THIS PRECIPITATION WAS
TRACKING NORTHEAST OUT OF NEW MEXICO. SNOWFALL DEVELOPMENT THIS
AFTERNOON WAS SUPPORTED BY INCREASING DEEP ISENTROPIC ASCENT AND THE
ENTRANCE REGION OF THE POLAR JET. SUBTLE WARM LAYERS DEPICTED ON 18Z
SPRINGFIELD SOUNDING HAD BEEN OVERCOME AS LOWER TROPOSPHERIC COLUMN
SATURATED. HOWEVER RECEIVING REPORTS OF SOME RAIN AT 21Z IN CHEROKEE
COUNTY KANSAS UNDERNEATH MORE INTENSE RADAR RETURNS.

AS THE UPPER LOW APPROACHES THIS EVENING SYNOPTIC SCALE LIFT WILL BE
ENHANCED BY INCREASING DIFFLUENCE ALOFT. IN ADDITION WARM AIR/THETA-
E WILL INCREASE AS THE LOW LEVEL JET STRENGTHENS. SNOW WILL CONTINUE
THROUGH THE EVENING BUT SOME QUESTION ABOUT SLEET POTENTIAL. THE
ZERO LINE AT 850 MB EXTENDS ACROSS FAR NORTHERN ARKANSAS AT 20Z AND
MODEL SOUNDINGS SUGGEST SOME SUBTLE WARMING WILL TAKE PLACE THIS
EVENING ABOVE 850 MB. EXPECT THE SLEET TO MIX IN WITH THE SNOW AT
TIMES MAINLY ALONG AND SOUTH OF I-44. PRECIPITATION MAY GO TO ALL
SLEET AND MIX WITH RAIN IN FAR SOUTH CENTRAL MISSOURI. THE EXTENT OF
SLEET WILL COMPLICATE SNOW ACCUMULATION POTENTIAL. HOWEVER STILL
EXPECT 3 TO 5 INCHES WITH LOCAL AMOUNTS NEAR 6 INCHES MAINLY NORTH
OF I-44. SOME CONCERN SLEET COULD APPROACH 1/2 INCH ACROSS FAR
SOUTHERN MISSOURI. THERE IS AN OUTSIDE CHANCE FOR SOME FREEZING RAIN
BUT PROGGED SOUNDINGS MORE SUPPORTIVE OF A SNOW SLEET MIX. WILL
REPLACE PORTIONS IF NOT ALL OF THE SNOW ADVISORY WITH A WINTER
WEATHER ADVISORY FOR THE POTENTIAL MIX OF PRECIPITATION.

PRECIPITATION WILL TAPER OFF LATE TONIGHT INTO SUNDAY MORNING AS THE
UPPER LOW LIFTS NORTHEAST ACROSS THE UPPER MIDWEST AND THE WARM
CONVEYOR BELT IS SHUNTED EAST. EXPECT ONLY MODEST RISES IN
TEMPERATURES SUNDAY AS STRATUS REMAINS ACROSS THE AREA. PROGGED
SOUNDINGS SUPPORT DRIZZLE OR FREEZING DRIZZLE SUNDAY INTO SUNDAY
NIGHT.

LONG TERM (MONDAY THROUGH TUESDAY)...

UPPER TROUGH PUSHES THROUGH MONDAY AFTERNOON. SHOULD KEEP US IN SOME
CLOUDINESS AND COLDER TEMPERATURES THROUGH MOST OF THIS TIME PERIOD.
BEING OUT OF THE NORTHWEST AND WITH NO GULF MOISTURE TAP...WE SHOULD
BE DRY PRECIPITATION WISE.

WEDNESDAY ON...ANOTHER NORTHERN SHORTWAVE BEGINS TO PUSH INTO THE
CENTRAL U.S. LATE TUESDAY NIGHT INTO WEDNESDAY. START TO SEE A
RETURN OF GULF MOISTURE AS GFS SHOWING MODEST QPFS INTO CENTRAL
ARKANSAS. THIS MOISTURE QUICKLY PUSHES OFF TO THE EAST AS THE TROUGH
PASSES...SO DO NOT THINK WE SHOULD SEE ANY WIDESPREAD POPS. KEPT SLT
CHC POPS GOING ACROSS EASTERN HALF OF THE CWA. COLD AIR STAYS FIRMLY
IN PLACE WITH NORTH TO NORTHWEST FLOW. LOOKING AT LOW TO MID 30S FOR
HIGHS THROUGH MOST OF THE WEEK AND HIGH TEENS TO LOW 20S FOR LOWS.

.AVIATION...

THE MAIN AVIATION FORECAST CHALLENGE WAS DETERMINING PRECIPITATION
TYPE THROUGH THE EVENING AND OVERNIGHT HOURS.  AN ELEVATED AREA OF
WARMER TEMPERATURES CAUSED SNOW TO CHANGE OVER TO RAIN AND FREEZING
RAIN FOR MOST AREAS OF SOUTHERN MISSOURI (INCLUDING JOPLIN AND
SPRINGFIELD AIRPORTS).  WEST CENTRAL MISSOURI TO CENTRAL MISSOURI
ARE STILL DEALING WITH ALL SNOW...WHERE ACCUMULATIONS HAVE EXCEEDED
2 INCHES IN MANY LOCATIONS.  LOOK FOR WINDS TO REMAIN OUT OF THE
EAST SOUTHEAST OVERNIGHT...WHILE CEILINGS AND VISIBILITIES FALL
GRADUALLY INTO MVFR AND IFR OVERNIGHT.
