The episode as NWS GRB wrote it up.
Low pressure moved from the central Plains into southern Wisconsin. The storm produced a swath of heavy, wet snow across northwest and north central Wisconsin and freezing rain across central and far northeast Wisconsin.
The heaviest snowfall was 14.5 inches a few miles southwest of Lac du Flambeau (Vilas Co.) and in Presque Isle (Vilas Co.). Most locations in north central Wisconsin received 6 to 9 inches of snow. Freezing rain accumulations of 0.25 to 0.40 were reported across central Wisconsin.
Despite the heavy, wet snow and ice accumulation, there was only isolated damage to trees and power lines.

AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE GREEN BAY WI 406 PM CDT THU APR 3 2014 FORECAST DISCUSSION FOR ROUTINE AFTERNOON FORECAST ISSUANCE .SHORT TERM...TONIGHT AND FRIDAY ISSUED AT 405 PM CDT THU APR 3 2014 IMPACTS OF A MAJOR STORM SYSTEM MOVING INTO THE REGION ARE THE MAIN CONCERNS IN THE SHORT TERM. THERE WAS A SHALLOW LAYER...50 TO 100MB DEEP...OF DRY AIR ON THE 12Z GRB SOUNDING BELOW 850MB. LOW LEVEL FLOW WAS EASTERLY AND APX 12Z SOUNDING WAS DRY BELOW 700MB. THIS DRIER AIR WAS EVIDENT IN THE MODEL QPF FIELDS...WHERE EASTERN WISCONSIN WAS FORECAST TO BE PRETTY MUCH DRY TODAY. THERE WAS A VARIETY OF SCATTERED LIGHT PRECIPITATION TODAY IN THE FORECAST AREA. THINGS SEEM A BIT MORE CLEAR-CUT ACROSS THE NORTHWEST PART OF THE AREA WHERE TEMPERATURES WILL BE COLD ENOUGH FOR SNOW AND MODELS HAD HIGH QPF TOTALS TONIGHT THROUGH FRIDAY IN THE DEFORMATION ZONE. HAVE A WINTER STORM WARNING GOING FOR THAT AREA WITH SNOW TOTALS IN EXCESS OF A FOOT NEAR THE UPPER MICHIGAN BORDER.

THIS WOULD HAVE MAJOR IMPACTS IF IT WERE TO OCCUR. TOTALS THIS HIGH SEEM A BIT EXTREME BUT CANNOT BE RULED OUT. THE 12Z GFS AND 12Z GEM-NH WERE A BIT COOLER THAN THE 12Z NAM IN THE WARM LAYER SO IT IS STILL POSSIBLE THAT THERE WOULD BE MORE SLEET THAN FREEZING RAIN. ENDED UP UPGRADING FROM WINTER STORM WATCH TO WINTER STORM WARNING EARLIER IN THE DAY DUE TO THE POTENTIAL FOR SLEET...FREEZING RAIN OR SOME TYPE OF WINTRY MIX. IT IS POSSIBLE THAT AN ICE STORM WARNING WOULD BE NEEDED IN PART OF THE FORECAST AREA LATER TONIGHT...DEPENDING UPON TRENDS.
