The episode as NWS LBF wrote it up.
A winter storm system ejecting out of the Southwestern U.S. moved slowly across Western and North Central Nebraska on December 7th and 8th. As the initial disturbance passed across, snow accumulations of 2 to 4 inches fell across portions of Western Nebraska during the afternoon and evening of December 7th. Light snow accumulations less than an inch along with areas of freezing rain and sleet occurred across the remainder of the area. As the main upper level system passed across Western and North Central Nebraska on December 8th, additional snow accumulations of 3 to 5 inches occurred, bring storm total snowfall amounts up to 9 inches in Garden county, and 6 to 7 inches across Grant, Arthur, McPherson, Deuel, and Keith County.

NWS North Platte, NE wrote its last area forecast discussion before the first event at Dec 7, 3:32 AM CST, 8 hours 28 minutes earlier.
AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE NORTH PLATTE NE 332 AM CST FRI DEC 7 2007 .SYNOPSIS... WV IMAGERY SHOWS A SHORTWAVE TROUGH DIGGING SOUTHEAST INTO CALIFORNIA. AS THIS FEATURE BECOMES ESTABLISHED OVER THE SOUTHWESTERN CONUS...A RIDGE WILL AMPLIFY ACROSS THE GREAT PLAINS. THIS WILL SET THE STAGE FOR A PROLONGED PERIOD OF PRECIPITATION OVER THE HIGH PLAINS FRIDAY INTO SUNDAY. MEANWHILE...ASCENT ASSOCIATED WITH A REGION OF MID LVL FRONTOGENESIS IS LEADING TO A BAND OF LIGHT REFLECTIVITY/PRECIPITATION OVER COLORADO AND KANSAS AT 09Z...AND IS FCST TO SPREAD NORTHWARD THROUGH FRIDAY. && .SHORT TERM...FRIDAY THROUGH SUNDAY MORNING... MOIST ISENTROPIC UPGLIDE AND WEAK MID LVL FRONTOGENESIS WILL SPREAD NORTH ACROSS WESTERN NEBRASKA ON FRIDAY. AIRMASS WILL INITIALLY BE AT OR SLIGHTLY BELOW FREEZING BY 18Z...WITH CLOUD TOP TEMPERATURES AROUND -15 DEG C. THIS SHOULD RESULT IN LIGHT SNOW DEVELOPING ALONG AND SOUTH OF I80...AND WEST OF HWY 83 AS WE HEAD INTO EARLY FRIDAY AFTERNOON. HIGH PRESSURE AT THE SFC IS FCST TO STRENGTHEN OVER THE NORTHERN PLAINS BY 00Z SATURDAY...RESULTING IN A TIGHT SFC PRESSURE GRADIENT. EAST WINDS AND PERSISTENT CLOUD COVER WILL RESULT IN HIGHS AROUND FREEZING OVER OUR WESTERN/SOUTHWESTERN COUNTIES...AND 20S OVER THE NORTH AND EAST. AS THE HIGH CONTINUES TO STRENGTHEN...MUCH COLDER AIR IS FCST TO SHIFT SOUTH ACROSS NEBRASKA SATURDAY MORNING. THIS WILL ALLOW TEMPERATURE PROFILES TO DROP WELL BELOW FREEZING...RESULTING IN HIGHER SNOWFALL RATIOS. MEANWHILE...A S/W TROUGH IS FCST TO EJECT NORTHEAST FROM THE LARGE SCALE TROUGH OVER THE SOUTHWESTERN CONUS SATURDAY MORNING. AS THIS OCCURS...RRQ OF H25 JET WILL LIFT NORTH ACROSS THE NORTHERN PLAINS...WHICH SOULD PROVIDE FAVORABLE PATTERN OF SYNOPTIC SCALE ASCENT ACROSS OUR CWA...AND IS SUPPORTED BY INCREASING Q-VECTOR CONVG DURING THE 12Z TO 18Z TIME FRAME. ISENTROPIC LIFT AND MOISTURE TRANSPORT ON THE 300 K SFC ARE MAXIMIZED DURING THIS TIME FRAME...AS WELL AS STRONG H7 WAA...AND ARE FCST TO SLOWLY SHIFT NORTH ACROSS THE CWA THROUGH SATURDAY AFTERNOON. FCST SOUNDINGS ACROSS THE CWA ALL SUPPORT SNOW AS THE PREDOMINANT PRECIP TYPE...WITH SATURATION OBSERVED UP THROUGH -20 DEG C...SUPPORTING DENDRITIC SNOW. THE COMBINATION OF DEEP SATURATED ATMOSPHERE...PERSISTENT LIFT THROUGHOUT MOST OF SATURDAY...AND FAVORABLE THERMODYNAMIC ENVIRONMENT SEEM TO POINT TOWARD A HEAVY SNOWFALL EVENT...PARTICULARLY ACROSS OUR WESTERN AND NORTHERN COUNTIES. ALTHOUGH MESOSCALE ASCENT WILL NOT BE PARTICULARLY INTENSE...DUE TO A LACK OF STRONG FRONTOGENESIS...STEADY SNOWFALL THROUGH 00Z SUNDAY IS EXPECTED TO LEAD TO TOTAL ACCUMULATIONS OF 6-8 INCHES. THUS HEAVY SNOW WARNING HAS BEEN POSTED FOR LOCATIONS ALONG AND NORTHWEST OF A LINE FROM OGALLALA TO NEWPORT. THE REMAINDER OF THE CWA WILL BE UNDER A SNOW ADVISORY. WARNING AND ADVISORY CRITERIA ARE EXPECTED TO COME TO AN END BY 00Z SUNDAY. BESIDES THE UPCOMING WINTER WEATHER EVENT...TEMPERATURES ARE EXPECTED TO BECOME QUITE COLD BY SUNDAY MORNING...WITH LOWS DROPPING INTO THE SINGLE DIGITS. IT APPEARS THAT CLOUD COVER WILL CONTINUE TO PERSIST...WHICH WILL PREVENT FURTHER COOLING SUNDAY MORNING...GIVEN THE EXPECTED SNOW COVERED GROUND. GFS AND NAM DIVERGE SUNDAY WITH THE TIMING OF A SECOND DISTURBANCE EMNATING FROM THE SOUTHWESTERN TROUGH. THIS S/W IS EXPECTED TO INTERACT WITH A SOUTHWEST/NORTHEAST LOW/MID LVL THERMAL GRADIENT...LEADING TO A SECOND ROUND OF SNOWFALL...MAINLY ACROSS OUR SOUTHERN AND EASTERN COUNTIES SOMETIME AROUND 06Z-12Z SUNDAY. LATER FCSTS WILL BE ABLE TO MORE ACCURATELY DETERMINE THE EVOLUTION OF THIS NEXT ROUND OF PRECIP. .LONG TERM...SUNDAY THROUGH TUESDAY NIGHT OMPLICATED FCST CONTINUES LATE WEEKEND INTO EARLY NEXT WEEK FOR MANY REASONS. HIGH AMPLITUED E.PAC TROF WILL KEEP SYSTEMS DROPPING SOUTHWARD INTO ANOMALOUS WESTERN CONUS TROF. CLOSED LOWS WILL TEMPORARILY TAKE UP RESIDENCE IN VCNTY OF BAJA REGION...BEFORE BEING EJECTED BY ARRIVING SYSTEMS AND PUSHED OVER CENTRAL ROCKIES. THIS CYCLE LOOKS TO CONTINUE THROUGH MID WEEK BEFORE STRONGER NORTHERN STREAM CLIPPER TYPE SYSTEM CLEARS OUT THE WESTERN CONUS AND NW FLOW PATTERN RETURNS. PERSISTANT STRONG H.BAY VORTEX WILL BE MAIN AID IN BRINGING THIS CHANGE ABOUT. HOWEVER THIS GENERAL PATTERN NEXT FEW DAYS HAS MANY TWISTS IN IT ACCORDING TO WHICH MODEL SOLN YOU LEAN...WITH OVERALL CONFIDENCE IN ANY SOLN VERY LOW. SYSTEM NOW DIVING ACROSS CALI WHICH WILL BE PIONEER IN CARVING OUT LOW WILL BE THE FIRST WAVE TO BE EJECTED INTO HIGH PLAINS BY EARLY SUNDAY. EURO/GFS SIMILAR IN TIMING WITH LARGE SCALE LIFT VIA Q-VECT CONVERGENCE ARRIVES BY SUNRISE AND SNOW SHOULD BE PRESENT MUCH OF THE DAY...HOWEVER NAM/SREF MUCH SLOW AND DRIER. MADE A FEW TWEAKS TO PCPN FCST WITH PUSHING POPS FARTHER NORTH BUT KEPT SPIRIT OF FCST IN TACT WITH HIGHEST POPS ACROSS EASTERN ZONES. SREF EVEN SHOWING SOME IMPRESSIVE SNOW AMOUNTS ACROSS EASTERN NEB. SHOULD SEE BREAK SUNDAY NIGHT TOWARD MID DAY MONDAY BETWEEN SYSTEMS ACCORDING TO SIMILAR EURO/GFS SOLNS...HOWEVER GFS SLIGHTLY FASTER PUSHING STRONGER ASCENT INTO AREA MONDAY AFTERNOON. THIS COULD BE DUE TO NORTHERN STREAM FLOW IS STRONGER IN EURO...WITH CONFLUENT FLOW ACROSS NORTHERN PLAINS...GFS HAS THIS FLOW JUST ACROSS CANADIAN BORDER. EITHER WAY LOOKS LIKE BETTER CHANCE OF SNOW MONDAY NIGHT INTO TUESDAY. FINAL LOW IN SW WILL BE PUSHED WELL SOUTH OF CWA BY DOMINATE N. STREAM WITH BREAK IN SNOW THROUGH LATE WEEK. TEMPS SHOULD TAKE A HIT AS ARCTIC AIR CONTINUES TO FEED INTO AREA THROUGH SUNDAY...ALSO ALLOWING FOR INFLATED SNOW RATIOS. KEPT THINGS QUITE COOL WITH EXPECTED DEEP SNOW PACK. && .AVIATION... LIFR AND IFR CONDITIONS TO PERSIST OVER SOUTHWEST NEBRASKA THROUGH THE NEXT 24 HRS WITH SNOW AFTER 15Z KLBF AND THEN SPREADING NORTH OVERNIGHT.
