The episode as NWS GRB wrote it up.
A narrow band of heavy snow fell over northeast Wisconsin as a strengthening low pressure system moved from central Lake Michigan to northern Lake Huron. Snow totals in the band were mainly in the 6 to 8 inch range. Some of the highest totals included: 8.2 inches near Florence (Florence Co.), 7.0 inches at Crandon (Forest Co.), and 6.0 inches at Antigo (Langlade Co.) and Phelps (Vilas Co.).

NWS Green Bay, WI wrote its last area forecast discussion before the first event at Apr 9, 8:35 PM CST, 2 hours 25 minutes earlier.
AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE GREEN BAY WI 935 PM CDT THU APR 9 2015 UPDATED AVIATION PORTION FOR 06Z TAF ISSUANCE AND NEW INFORMATION ADDED TO UPDATE SECTION .UPDATE... ISSUED AT 929 PM CDT THU APR 9 2015 HAVE DECIDED TO UPGRADE MY NW/NRN 4 COUNTIES TO A WINTER STORM WARNING. NOT A CLEAR-CUT SITN AT ALL...BUT GIVEN THE STRENGTH OF THE DYNAMICS TO COME ACRS THAT AREA LATER IN THE NGT...COULD EASILY SEE SOME 1-2 INCH PER HOUR SNOWFALL RATES. WL CALL FOR 4-8 INCH TOTALS IN THE WSW. THINK THE HIGHEST TOTALS WILL END UP IN AN AREA NE OF A LINE FROM BOULDER JUNCTION...TO RHINELANDER...TO CRANDON...TO FLORENCE. ELSEWHERE ACRS THE AREA...INITIAL SURGE OF PCPN HAS SHIFTED THROUGH...BUT EXPECT SOME REDEVELOPMENT AHEAD OF THE MAIN SHRTWV. WL KEEP HIGH POPS GOING MOST OF THE NGT. UPDATED PRODUCT SUITE WL BE OUT ASAP. UPDATE ISSUED AT 536 PM CDT THU APR 9 2015 FCST ISSUES SPAN THE SEASONS THIS EVENING AS STRENGTHENING CYCLONE LIFTS NEWD FM IA. CLUSTER OF SVR STORMS IN S-C WI HEADING NE. LOCAL MESO PLOTS SHOW POOL OF INSTABILITY EXPANDING NE...BUT NOT AS QUICKLY AS THE STORMS ARE MOVG NE. IT/S GOING TO BE A CLOSE CALL ON WHETHER A SVR STORM COULD CLIP THE SRN PART OF THE FCST AREA BEFORE WEAKENING. THE PRIMARY SVR THREAT WOULD BE HAIL...AND THINK THAT WOULD NEED TO HAPPEN WITHIN THE NEXT COUPLE HRS...BEFORE PCPN GETS TOO WIDESPREAD. IT/S A COMPLETELY DIFFERENT SITN ACRS THE NW CORNER OF THE FCST AREA...WHERE THE THREAT IS HEAVY SNOW. WATCHING THE UPR DEFORMATION ZONE EXPAND NEWD AS MAIN SHRTWV EJECTS TOWARD WI. EXTRAOLATION OF SRN EDGE OF THE DEFORMATION ZONE WOULD BRING IT ACRS THE NW PART OF THE FCST AREA. MAIN QUESTIONS FOR SNOW AMNTS CONTINUE TO BE TIMING OF THE CHANGEOVER AND HOW MUCH PCPN FALLS AFTER THAT TIME. NRN STREAM SHRTWV EDGING IN FM THE NW MAY TEND TO DISRUPT THE COMMA HEAD AND NUDGE IT EWD...LIMITING THE AMNT OF PCPN THAT FALLS AFTER THE CHANGEOVER. ON THE OTHER HAND...PCPN COULD BE FALLING QUITE HEAVILY AFTER THE CHANGEOVER...SO THE POTENTIAL IS THERE FOR A PERIOD OF HEAVY SNOW. NEED TO WATCH THIS VERY CLOSELY...BUT LIKELY WON/T BE ABLE TO MAKE ANY HEADLINE CHANGES UNTIL WE START TO SEE THE CHANGEOVER OCCURRING. && .SHORT TERM...TONIGHT AND FRIDAY ISSUED AT 241 PM CDT THU APR 9 2015 THE LATEST RAP ANALYSIS AND SATELLITE/RADAR IMAGERY SHOW LOW PRESSURE HEADING NORTHEAST AS IT ENTERS SOUTH-CENTRAL IOWA EARLY THIS AFTERNOON. COMMA HEAD PRECIPITATION IS OCCURRING JUST TO THE REAR OF THE PRIMARY SHORTWAVE LOCATED OVER CENTRAL NEBRASKA...WHERE HEAVY SNOW AND A FEW LIGHTNING STRIKES HAVE BEEN DETECTED. DOWNSTREAM OF THE SYSTEM...A SHORTWAVE IMPULSE IS GENERATING SHOWERS AND THUNDERSTORMS OVER THE EASTERN HALF OF WISCONSIN. MOST OF THE THUNDERSTORM ACTIVITY HAS DIMINISHED AS THEY REACHED THE WAUTOMA TO MANITOWOC CORRIDOR SINCE ELEVATED INSTABILITY HAS NOT BEEN ABLE TO EXTEND THAT FAR NORTH. AS A RESULT...LOOK FOR PERIODS OF SHOWERS AND DRIZZLE TO CONTINUE TO IMPACT THE REGION FOR THE REST OF THE AFTERNOON. THE MAIN FORECAST CONCERNS REVOLVE AROUND HEAVY WINTRY PRECIP ACROSS THE NORTH AND THUNDERSTORM CHANCES OVER THE SOUTH AS A CYCLONE PASSES ACROSS THE REGION TONIGHT. TONIGHT...THE STRONG SHORTWAVE OVER NEBRASKA WILL SWING NORTHEAST AS IT PUSHES A SURFACE LOW FROM THE NORTHWEST CORNER OF ILLINOIS TO CENTRAL LAKE MICHIGAN TO THE STRAITS OF MACKINAC. AHEAD OF THE LOW...ELEVATED INSTABILITY UP TO 500 J/KG MAY SNEAK INTO EAST-CENTRAL WISCONSIN WITHIN A REGION OF STRONG UPWARD MOTION WHICH COULD GENERATE SCATTERED THUNDERSTORMS THOUGH AROUND MID-EVENING. IF THUNDERSTORMS DO OCCUR...SMALL HAIL WILL BE POSSIBLE. TO THE NORTH OF THE LOW...EXCELLENT UPPER DIVERGENCE COMBINED WITH STRONG MID-LEVEL FGEN AND REDUCED STABILITY WILL LEAD TO A HEALTHY DEFORMATION BAND DEVELOPING FROM WEST-CENTRAL TO NORTH-CENTRAL WISCONSIN. THIS DEFORMATION BAND WILL BRING A PROLONGED PERIOD OF MODERATE TO HEAVY PRECIP AT TIMES. WITH TEMPS AND DEWPOINTS IN THE MIDDLE 30S AT THE START OF THE EVENING...PRECIP WILL LIKELY BE ALL RAIN FOR THE FIRST COUPLE HOURS. THEN COLDER AIR WILL GRADUALLY GET DRAWN INTO NORTH-CENTRAL WISCONSIN TO CHANGE PRECIP TO SLEET AND THEN SNOW. BUFKIT SOUNDINGS INDICATE THAT THE NORTH COULD SEE A FEW HOUR PERIOD OF SLEET WHICH COULD LEAD TO DECENT SLEET ACCUMULATIONS GIVEN THE EXPECTED PRECIP RATES. THEN ONCE TEMPS COOL ENOUGH FOR ALL SNOW...SNOWFALL RATES COULD EASILY EXCEED AN INCH PER HOUR AT TIMES. BUT ONE OF THE MOST DIFFICULT ASPECTS OF THIS FORECAST IS IN REGARDS TO HOW QUICKLY THIS CHANGE OVER OCCURS SINCE COLD AIR IS NOT THAT PLENTIFUL TO OUR NORTH. BEST GUESS FROM GUIDANCE INDICATES THIS CHANGE OVER WILL OCCUR LATE THIS EVENING OVER N-C WISCONSIN AND EARLY OVERNIGHT OVER TO CENTRAL WISCONSIN TO THE IRON MOUNTAIN AREA. THE INITIAL RAIN AND SLEET WILL EAT UP SOME OF THE QPF AMOUNTS THIS EVENING...BUT GUIDANCE STILL POINT TOWARDS OVER A HALF INCH FALLING AFTER 06Z. ADDITIONALLY...THE HI-RES MODELS ARE ALSO INDICATING BANDING TAKING PLACE...AND A LITTLE FARTHER TO THE EAST THAN SHOWN PREVIOUSLY. HAVE SHIFTED QPF AND SNOW AMOUNTS TO THE EAST AS A RESULT...WHICH GIVES SNOW AMOUNTS OF 3-6 INCHES FROM LINCOLN AND LANGLADE ON NORTH. A QUARTER TO A HALF INCH OF THAT COULD TURN OUT TO BE SLEET ACCUMULATION. LOCALLY HIGHER AMOUNTS WILL BE POSSIBLE DEPENDING ON WHERE THE SNOW BANDS SET UP. BECAUSE OF THIS UNCERTAINTY...WILL ISSUE A WINTER WEATHER ADVISORY FROM 02Z-13Z. FRIDAY...PRECIP WITH SNOW WEST OF THE FOX VALLEY AND RAIN TO THE EAST WILL DIMINISH EARLY FRIDAY MORNING. SHOULD SEE A CLOUDY AND WINDY START TO THE DAY OTHERWISE. A TRAILING SHORTWAVE WILL PUSH ACROSS SOUTHERN WISCONSIN DURING THE AFTERNOON WHICH COULD CREATE AN ISOLATED SHOWER OVER THE NORTHERN HALF OF THE STATE. LEFT A SMALL CHANCE TO ACCOUNT FOR THIS. HIGHS RANGING FROM THE LOW 40S NORTH TO LOW 50S SOUTH. .LONG TERM...FRIDAY NIGHT THROUGH THURSDAY ISSUED AT 241 PM CDT THU APR 9 2015 PCPN TRENDS SUNDAY/SUNDAY NIGHT AND DURING THE MIDDLE OF NEXT WEEK ARE THE MAIN FCST CONCERNS. HIGH PRESSURE IS EXPECTED TO BUILD INTO THE REGION FRIDAY NIGHT. USED A BLEND OF THE BETTER PERFORMING GUIDANCE SETS FOR MIN TEMPS...BUT WITH THE POTENTIAL FOR A LINGERING SNOW COVER OVER NC WI...HAVE BUMPED MIN TEMPS DOWN THERE. HIGH PRESSURE WILL BRING DRY CONDITIONS SATURDAY AND SATURDAY NIGHT... WITH DEVELOPING SOUTH FLOW RESULTING IN MODERATING TEMPERATURES. A COLD FRONT WILL MOVE INTO WESTERN WI ON SUNDAY AFTERNOON...THEN ACROSS THE FORECAST AREA SUNDAY EVENING. HAVE SLOWED DOWN THE ARRIVAL TIME OF SHOWERS ON SUNDAY AFTERNOON (MAINLY NC/C WI LATE IN THE DAY)...BUT WILL SPREAD HIGH CHC/LOW LIKELY POPS OVER THE ENTIRE CWA SUNDAY NIGHT. H8 LI'S SLIGHTLY BLO ZERO AND STEEP MID- LEVEL LAPSE RATES SUGGEST POTENTIAL FOR AT LEAST ISOLD TSTMS...SO HAVE INCLUDED A SLGT CHC OF TSTMS. HIGH PRESSURE AND AND ASSOCIATED DRY AND MILD CONDITIONS WILL RETURN TO WISCONSIN ON MONDAY AND TUESDAY. THE FCST BECOMES A BIT MUDDLED DURING THE MIDDLE OF THE WEEK...AS SW FLOW ALOFT DEVELOPS AND LOW PRESSURE AND AN ASSOCIATED COLD FRONT EDGE TOWARD THE WESTERN GREAT LAKES. MOST MODELS NOW KEEP TUESDAY NIGHT DRY...WITH THE ECMWF BRINGING PCPN INTO THE REGION ON WEDS...AND THE GFS HOLDING OFF UNTIL ABOUT THURSDAY. GIVEN THE UNCERTAINTY...WILL CARRY CHC POPS THROUGH THIS PERIOD. THE GOOD NEWS IS THAT ANY PCPN THAT OCCURS SHOULD FALL AS ALL RAIN...WHICH IS DEFINITELY A STEP IN THE RIGHT DIRECTION. && .AVIATION...FOR 06Z TAF ISSUANCE ISSUED AT 929 PM CDT THU APR 9 2015 MAY NOT NEED TO CARRY THUNDER IN THE 06Z TAFS...WL MAKE AN ISSUANCE TIME DECIDISON ON THAT. OTHERWISE...VERY POOR FLIGHT CONDITIONS DURING THE FIRST PORTION OF THE TAF PERIOD WL GRADUALLY IMPROVE FRIDAY AS THE CYCLONE PULLS AWAY FM THE REGION. && .GRB WATCHES/WARNINGS/ADVISORIES...
