What happened

The episode as NWS DVN wrote it up.

A storm system moved out of the central Plains into northern Missouri late on 1/13 into early 1/14. Surface temperatures near or a few degrees above freezing, combined with a warmer layer aloft, produced conditions ideal for a mix of rain, freezing rain, sleet, and snow across the area. The precipitation spread from eastern Iowa into western Illinois during the evening hours of 1/13. Ice accumulations up to 1/8 inch created slick driving conditions. Several accidents were reported during the overnight hours in far northwest Illinois. Snowfall accumulations were mainly limited to areas north of Interstate 80, where amounts ranging from a few tenths up to one inch were reported. Occasional light snow tapered to flurries across parts of far northwest Illinois, during the morning of 1/14. Flurries and light drizzle lingered through the afternoon hours, as the storm tracked into northwest Illinois.

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE QUAD CITIES IA IL
300 PM CST SAT JAN 13 2001

LATEST SURFACE ANALYSIS INDICATING SURFACE LOW DEVELOPING OVER SW
KS...WITH SOME PRETTY GOOD PRESSURE FALLS EXTENDING TO ITS EAST INTO
NORTH CENTRAL MO.  LOW LEVELS OF UPPER AIR ANALYSIS INDICATING SOME
GOOD WARM AIR ADVECTION OCCURRING ACROSS SOUTHERN PLAINS...WHICH
SHOULD KEEP TEMPS ABOVE FREEZING AT 850 MB FOR AT LEAST THE NEXT 12
HRS.  UPPER LEVELS INDICATING A DOUBLE STRUCTURE TO THE NEGATIVELY
TILTED TROUGH...WITH GOOD HEIGHT FALLS ACROSS THE PLAINS ABOVE ALL
THAT WARM AIR ADVECTION.  SYSTEM STRENTHENING NICELY.

...PROBLEMS THIS FORECAST PACKAGE INCLUDE WHERE TO CONTINUE WIN WX
ADVISORY FOR SNOW/ICE ACCUMS TONIGHT...AND WHETHER IT NEEDS TO BE
EXTENDED INTO SUNDAY...

LATEST MODEL RUNS COMING MORE IN AGREEMENT...AND SHIFTING FURTHER
NORTH THAN ON PREVIOUS RUNS.  ETA MAKES A RATHER DRAMATIC SHIFT N
WITH THE SURFACE LOW...AND IS NOW FURTHER NORTH THAN THE AVN...WHICH
HAD BEEN THE NORTHERN ONE BEFORE.  THE BIG QUESTION IS HOW THE
RAIN/SNOW LINE WILL LAY OUT...AND HOW LARGE AN AREA OF FREEZING
RAIN/SLEET WE WILL HAVE.  THE SOUNDINGS AND SURFACE TEMPS DO NOT
LOOK AS FAVORABLE FOR FREEZING RAIN/SLEET ACROSS THE CWA AS THE
PARTIAL THICKNESSES WOULD HAVE US BELIEVE.  WARMER SURFACE TEMPS
ACROSS THE SOUTH HINT MORE AT RAIN THAN FREEZING RAIN...THOUGH WITH
PERSISTENT SNOW COVER SOME FREEZING RAIN IS POSSIBLE...SO WILL
MENTION IT IN ZONES.  ACROSS THE NORTHWEST...COLDER TEMPERATURES AT
THE SURFACE AND QUICKLY COOLING MODEL SOUNDINGS FAVOR MORE
SNOW...THOUGH WILL MENTION THE POSSIBILITY OF A MIX THROUGH SUNDAY.
THIS LEAVES THE REAL MESS OF MIXED PRECIP ACROSS THE CENTRAL
PORTIONS OF CWA.  CURRENT WORDING IN THOSE ZONES FOR TONIGHT AND
SUNDAY LOOK FAIRLY GOOD...AND WILL STAY CLOSE.

HAVE DECIDED TO EXTEND ADVISORY INTO SUNDAY...MAINLY FOR THE AREA
OF INSTABILITY THAT MOVES ACROSS DURING THE DAY...AND WILL CONTINUE
TO MAKE CONDITIONS HAZARDOUS.

MONDAY...PRECIPITATION LINGERS ACROSS THE AREA...WITH LOW POPS AND
MORE OF A SNOW SHOWER WORDING.  WITH MOST OF THE SOUNDING BELOW
FREEZING AND ONLY A LITTLE ABOVE AT THE SURFACE...IT SHOULD REMAIN
ALL SNOW...BUT ACCUMULATE LITTLE DUE TO WET SNOW WATER EQUIVALENTS.
TEMPS COOLER IN MAV THAN GOING FCST...SO WILL TRIM SLIGHTLY.

EXTENDED...HAD A QUICK LOOK...WILL TWEEK TUESDAY SNOW WORDING MORE
TOWARDS SNOW SHOWERS RATHER THAN FLURRIES.  WED THRU FRI LOOK
GOOD...WILL PRETTY MUCH LEAVE ALONE. SATURDAY LOOKS DRY FOR
NOW...THOUGH THIS MAY NEED TO BE CHANGED AS THE SURFACE TROUGH
MOVING THROUGH MAY CAUSE SOME FLURRIES...BUT WITH LOW POPS DECIDED
TO LEAVE DRY FOR NOW.  TEMPS LIKELY TOO WARM AND WILL TWEEK TO JUST
SLIGHTLY WARMER THAN FRIDAY.

COORD WITH KILX...KLOT...KARX...KDMX...KMKE...THANKS.
