Looking like the main California system may fracture as it comes out in the plains but judging by the model spreads overnight, looks to me like in the Friday night to Saturday night timeframe there is a local threat for freezing drizzle or freezing rain, sleet, or snow - or a combination thereof locally.
From Hastings NWS: BOTH THE GFS AND NAM ARE NOW BRINGING A COLD FRONT THROUGH THE AREA FRIDAY NIGHT. SOME PRETTY GOOD FRONTOGENETICAL FORCING IS EVIDENT IN THE 700-600 MB LAYER.
From Omaha NWS: TONIGHT INTO FRIDAY HEIGHTS FALL WITH INCREASING MID LEVEL ZONAL FLOW TO INDUCE LEESIDE TROUGHING TO THE WEST. CONVERGENT UPSLOPE FLOW IN THE WEST WILL STEADILY MOISTEN THE AIR COLUMN WITH BOUNDARY LAYER MOISTURE FORECAST TO INCREASE FOR MORE CLOUDS GOING INTO FRIDAY. STRATUS LAYER MAY BE SLOW TO BURN OFF EARLY AS MID LEVEL CLOUDS ALSO INCREASE ON FRIDAY. POPS RETAINED WITH NORTHERN FORECAST AREA TO CONTINUE TO SEE THE BEST CHANCES FOR SNOW. BOUNDARY LINGERS IN THE WEST SATURDAY WITH PIECES OF ENERGY TO DROP SOUTHEAST SO POPS RETAINED IN THE NEAR TERM.
Official Omaha forecast:
FRIDAY NIGHT...MOSTLY CLOUDY WITH A 20 PERCENT CHANCE OF SNOW. LOWS AROUND 15. NORTHEAST WINDS AROUND 10 MPH.
SATURDAY...MOSTLY CLOUDY WITH A 30 PERCENT CHANCE OF SNOW. HIGHS IN THE UPPER 20S. NORTH WINDS 5 TO 15 MPH.
SATURDAY NIGHT...MOSTLY CLOUDY WITH A 30 PERCENT CHANCE OF SNOW. LOWS AROUND 14.
SUNDAY AND SUNDAY NIGHT...MOSTLY CLOUDY WITH A 20 PERCENT CHANCE OF SNOW. HIGHS IN THE MID 20S. LOWS AROUND 10.
