The episode as NWS OAX wrote it up.
The second ice storm in two weeks hit parts of eastern Nebraska and southwest Iowa from Monday evening December 10 into Tuesday morning the 11th. Warmer and more moist air spread northeast across the area Monday evening over a cold and least partially snow-covered ground. Temperatures earlier in the day were only in the 20s with most dew point temperatures in the teens.
Freezing rain moved into southeast Nebraska a little after 700 pm and spread northeast into the Omaha area by 930 or 10 pm. The northern section of the freezing rain mixed with sleet and then changed to snow by morning, with some 1 or 2 inch snow accumulations. The southern sections remained mostly freezing rain for most of the event. Ice accumulations ranged from around 1 inch in the southeast corner of Nebraska in Richardson and Pawnee counties, to around 1/4 inch from around Fremont through Blair, which are just to the northwest of Omaha. Especially hard hit were Pawnee and Richardson counties where many trees and power lines were downed along with prolonged power outages. Farther north from around Lincoln to Omaha, the freezing rain and sleet mixture appeared to limit the amount of icing that built up on power lines and trees with much less damage and power loss noted. However, the wintry weather forced the postponement of many schools across the area. The total damage was estimated at around $3.1 million, mostly in Pawnee, Richardson, Nemaha and southern Gage counties. Over 5,000 customers were without power for a while, some for days. President Bush declared that major disaster area money would be available for disaster assistance.

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE OMAHA/VALLEY NE
313 PM CST MON DEC 10 2007
.SHORT TERM...TONIGHT THROUGH THURSDAY.
FOR THE MOST PART HAVE FOLLOWED THE GFS SOLUTION FOR THE
IMPENDING WINTER STORM AS IT LOOKS TO HAVE A BETTER HANDLE ON
CONVECTION DEVELOPING TO OUR SOUTH AND RESULTANT INDUCED FLOW
AROUND THAT CONVECTION.
CONVECTION WAS ALREADY BREAKING OUT THIS AFTERNOON ACROSS THE
TEXAS PANHANDLE INTO OKLAHOMA...AHEAD OF VIGOROUS UPPER LOW
SPINNING INTO THE NORTHERN BAJA. 120M HEIGHT FALL/RISE COUPLET WAS
NOTED ON MORNING UPPER AIR CHARTS WITH THIS SYSTEM...AND WATER
VAPOR LOOPS WERE SHOWING CLASSIC DIVERGENT UPPER FLOW PATTERN
SPREADING NORTHEAST THROUGH THE SOUTHERN ROCKIES. SUB TROPICAL
MOISTURE WAS ALSO NOTED STREAMING NORTH INTO THE SYSTEM. AT THE
SURFACE...PRESSURE WAS LOWERING ALL ACROSS THE REGION...AND
ESPECIALLY IN THE HIGH PLAINS. SOUTHERLY FLOW WAS INCREASING
THERE...PUSHING SLIGHTLY HIGHER DEW POINTS INTO EASTERN NEBRASKA.
TEMPERATURES REMAINED IN THE LOW AND MID 20S IN THE SOUTHERN CWA
WHERE ICE STORM IS FORECAST.
SO FAR...THINGS SEEM TO BE EVOLVING AS EXPECTED IN THE LARGE
SCALE...SO ONLY THE FINER DETAILS NEED TO BE WORKED OUT.
FIRST...COPIOUS MOISTURE IS AVAILABLE FOR PRECIPITATION WITH THIS
SYSTEM...WITH THE MAIN QUESTION BEING HOW FAR NORTH SIGNIFICANT
AMOUNTS WILL MAKE IT. THEN OF COURSE IS THE IMPORTANT
PRECIPITATION TYPE QUESTION...AND WHERE/WHEN THE CHANGES WILL OCCUR.
MORNING SOUNDINGS SHOWED WEDGE OF WARM AIR EXTENDING THROUGH
EASTERN NEBRASKA...AND GFS KEEPS THIS IN PLACE THROUGH MUCH OF THE
NIGHT NEAR OMAHA AND SOUTH. FORECAST SOUNDINGS SUGGEST THE
INTERSTATE 80 CORRIDOR WILL BE THE DIVIDING LINE BETWEEN MAINLY
FREEZING RAIN TO THE SOUTH AND SNOW TO THE NORTH. HAVE FOLLOWED
THE GFS SOUNDINGS AS A GUIDE FOR PRECIP TYPE AND CHANGEOVER...AND
IT HAD SUPPORT FROM THE NAM AND VARIOUS SREF MEMBERS.
IT LOOKS LIKE FREEZING RAIN WILL BREAK OUT THIS EVENING IN THE
SOUTHWEST CWA THEN SPREAD RAPIDLY NORTHEAST BEFORE MIDNIGHT. GFS
QPF SUGGEST A QUARTER TO HALF INCH OF ICE IS POSSIBLE FROM
INTERSTATE 80 SOUTH BEFORE 6 AM...WITH SLIGHTLY HIGHER TOTALS IN
SOUTHEAST NEBRASKA WHERE UP TO AN INCH OF QPF COULD OCCUR. A
CHANGE OVER TO SLEET/SNOW WILL LIKELY OCCUR IN THE INTERSTATE 80
CORRIDOR BETWEEN 2 AND 6 AM...WITH MAINLY SNOW FALLING DURING THE
MORNING TUESDAY. THAT CHANGEOVER WILL CONTINUE SLOWLY SOUTHEAST
DURING THE MORNING...REACHING THE FALLS CITY AREA BY EARLY
AFTERNOON. HOWEVER MOST OF THE PRECIP THERE WILL BE ALL FREEZING
RAIN WITH TOTALS OVER AN INCH POSSIBLE. ONE CAVEAT IS THE GFS
SURFACE TEMPERATURES POINTING TO NEAR FREEZING TEMPS LATE TONIGHT
AND EARLY TUESDAY...WHICH WOULD HELP SOMEWHAT WITH ICE ACCRUAL.
HAVE PAINTED A STRIPE OF 2 TO 4 INCH SNOWS FROM INTERSTATE 80
NORTH WHERE CHANGE TO SNOW SHOULD OCCUR EARLY ENOUGH BEFORE SYSTEM
TRACKS EAST. HOWEVER...ANY PROLONGED PERIOD OF SLEET MAY ROB SOME
OF THE QPF SO SNOW TOTALS MAY BE A LITTLE LESS. BUT THEN
AGAIN...SOME QUICK BURSTS OF CONVECTIVE SNOWS ARE POSSIBLE AS FAR
NORTH AS OMAHA GIVEN NEGATIVE THETA-E LAPSE RATES SEEN IN CROSS
SECTIONS.
SNOW SHOULD END FROM NORTHWEST TO SOUTHEAST TUESDAY AFTERNOON AND
EVENING. GFS HAS SECOND AREA OF LIGHT SNOW/CLOUDS ROLLING ACROSS
THE AREA TUESDAY NIGHT...BUT ACCUMULATIONS SHOULD NOT BE
SIGNIFICANT. CLOUDS MAY LIMIT TEMPERATURES FROM FALLING TOO
MUCH...ESPECIALLY OVER FRESHLY FALLEN SNOW FIELD. IF SKIES CLEAR
OUT...LIGHT WINDS WILL ALLOW TEMPS TO DROP TO BELOW ZERO.
A SLIGHT WARMUP EXPECTED WEDNESDAY AS SOUTHERLY FLOW RETURNS AHEAD
OF NEXT CLIPPER SYSTEM SWINGING THROUGH THE NORTHERN PLAINS
WEDNESDAY NIGHT. NORTHWEST WINDS AND COOL ADVECTION EXPECTED
THURSDAY...BUT MIXING AND SOME SUNSHINE SHOULD PUSH TEMPS BACK
TOWARD 30.
.LONG TERM...THURSDAY NIGHT THROUGH MONDAY.
OVERALL...MODELS ARE IN RELATIVELY GOOD AGREEMENT WITH GENERAL
PATTERN IN THE EXTENDED PERIOD. SOME DIFFERENCES IN STRENGTH OF THE
UPPER WAVES SATURDAY AND SUNDAY WITH ECMWF SHOWING MORE INTENSITY.
GENERALLY LITTLE CHANGE TO FORECAST WITH TREND TOWARD HPC GUIDANCE.
DID REMOVE SLIGHT POPS IN PREVIOUSLY FOR SATURDAY DUE TO TIMING
UNCERTAINTY AMONG THE MODELS AND LIMITED QPF FOR THE CWA. SAME STORY
FOR THE SYSTEM ON SUNDAY THAT RACES THROUGH THE REGION.
