What happened
The episode as NWS GRB wrote it up.
A potent storm system moved out of the Rockies and across the nation's mid-section into Iowa and Illinois on February 20-21. Abundant moisture ahead of this storm led to the development of snow across central and east-central Wisconsin during the day February 20th. Thunder and lightning was reported with the heavy snow in several locations during the afternoon and evening at the height of the storm.
Very dry Canadian air, which moved into far northeast Wisconsin from the north, prevented much, if any snow, to fall there. This resulted in a large gradient of snowfall across the region. Twenty-four hour snowfall totals generally ranged from 8 to 12 inches along and near Highway 29 from Wausau to Green Bay.
An upper level low pressure system, which lagged behind the surface storm center, produced another 2 to 4 inches of snow on February 21, bringing two-day storm totals to 13.9 inches at Green Bay (Brown Co.) and 13.0 inches at Appleton (Outagamie Co.). All time two-day February snowfalls were broken at Wausau (Marathon Co.) with 13.5 inches and Stevens Point (Portage Co.) with 15.8 inches.

Area forecast discussion, Feb 20, 4:14 AM CST, 7 hours 46 minutes before
AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE GREEN BAY WI 414 AM CST SUN FEB 20 2011 .SHORT TERM...TODAY THROUGH MONDAY...MAIN FCST CONCERN IS THE WINTER WX HEADLINES. WV IMAGERY SHOWED A LARGE UPPER TROF MOVG ACROSS THE ROCKIES... WITH A 150 KT JET STREAK MOVG THROUGH THE FOUR CORNERS REGION EARLY THIS MORNING. AN 850 MB WARM FRONT WAS LIFTING NORTH THROUGH NEBRASKA...IOWA AND CENTRAL IL...WITH ELEVATED CONVECTION FIRING ALONG IT AS A 40-50 KT LOW-LEVEL JET ASCENDED THE FRONTAL ZONE. REGION RADAR MOSAIC SHOWED THE PCPN FOCUSED ALONG AND NORTH OF THE H8 WARM FRONT...AND JUST APPROACHING FAR SW WI. OVER GRB CWA...ONLY MID/HIGH LEVEL CLOUDS WERE NOTED. BASED ON CURRENT RADAR TRENDS...AND MODEL RH TIMESECTIONS SHOWING A LOW-LEVEL DRY LAYER LINGERING OVER C/NE WI EARLY THIS MORNING... HAVE DECIDED TO DELAY THE START TIME OF THE WINTER WX HEADLINES BY 3-6 HOURS. MODELS STILL SHOW IMPRESSIVE DYNAMICS DEVELOPING OVER GRB CWA...WITH COUPLED UPPER JETS AND STRONG/DEEP MID-LEVEL FRONTOGENETIC FORCING OVER THE REGION DURING THE AFTERNOON/EVENING HOURS. AM SOMEWHAT CONCERNED THAT CONVECTION TO OUR SOUTH WILL CUT OFF SOME OF OUR MOISTURE TRANSPORT THIS AFTERNOON AND EARLY EVG...SO BACKED OFF AN INCH OR TWO ON OUR SNOWFALL TOTALS FOR THE EVENT. AM ALSO CONCERNED THAT WEAK DRY SLOTTING SHOWN BY A FEW MODELS OVER OUR FAR SOUTHERN COUNTIES TONIGHT MAY DECREASE THE SNOW...OR EVEN BRIEFLY REMOVE THE ICE FROM THE COLUMN...LEADING TO A PERIOD OF FREEZING RAIN. NEEDLESS TO SAY... THERE ARE STILL SOME UNKNOWNS THAT MAY NEED TO BE ADDRESSED AS THE EVENT UNFOLDS. IN GENERAL...KEPT THE WINTER WX ADVISORIES ACROSS THE FAR NORTH... AND WINTER STORM WARNINGS FOR THE REST OF THE CWA. WILL DROP SNOW TOTALS TO 7 TO 11 INCHES IN THE WARNING AREA TO ACCOUNT FOR SOME OF THE CONCERNS MENTIONED ABOVE. KEPT THE END TIME FOR THE FOX VALLEY...BAYSHORE...LAKESHORE AREAS UNTIL 18Z MONDAY...TO ACCOUNT FOR EXPECTED BLOWING/DRIFTING DUE TO STG NE WINDS FUNNELING DOWN THE BAY AND OFF THE LAKE. LOCAL BLIZZARD CONDITIONS ARE PSBL TONIGHT. EXPECT THE SNOW TO GRADUALLY TAPER OFF FROM THE NORTH LATE TONIGHT INTO MONDAY. HOWEVER...AN UPPER LEVEL LOW PASSING TO OUR SOUTH WILL KEEP SOME LIGHT SNOW IN THE FCST OVER C/EC WI THROUGH THE DAY. WILL NEED TO KEEP AN EYE ON THIS FEATURE... AS IT COULD PRODUCE MORE SNOW THAN WE'RE CURRENTLY FORECASTING OVER OUR SOUTHERN COUNTIES. .LONG TERM...MONDAY NIGHT THROUGH SATURDAY COLD NORTHEAST FLOW OFF OF LAKE MICHIGAN WILL BRING A CHANCE OF SNOW SHOWERS TO THE LAKE MICHIGAN SHORELINE MONDAY NIGHT. SOME QUESTIONS LINGER ABOUT THE DRY AIR AT 850MB TO SUSTAIN MORE THAN LIGHT SNOW SHOWER ACTIVITY. FLOW TURNS TO THE SOUTH LATE MONDAY NIGHT. ON TUESDAY...HIGH PRESSURE WILL DOMINATE THE WEATHER PATTERN WITH WITH BELOW NORMAL TEMPERATURES. COLD FRONT WILL MOVE ACROSS THE AREA WEDNESDAY AFTERNOON AND WEDNESDAY NIGHT...BRINGING A CHANCE OF RAIN OR SNOW TO THE REGION. SOUNDING INDICATED BEST CHANCE FOR RAIN WILL BE ACROSS CENTRAL AND NORTHEAST WISCONSIN. ATTENTION THEN TURNS TO THE POTENTIAL WINTER STORM THAT WILL AFFECT THE REGION THURSDAY AND THURSDAY NIGHT. LATEST MODEL RUNS OF THE GFS/ECMWF TAKE THE SYSTEM SOUTH OF THE AREA WITH LITTLE OR NO PRECIPITATION ACROSS THE AREA. THE CANADIAN CONTINUE TO BRING SYSTEM INTO THE REGION WITH AN ACCUMULATING SNOWFALL TO THE SOUTHEAST TWO THIRDS OF THE FORECAST AREA. PER COORDINATION WITH SURROUNDING OFFICES...LOWERED POPS CONSIDERABLY THURSDAY NIGHT. I AM SURE WITH LATER RUNS..THIS SYSTEM WILL TREND FURTHER NORTH TO CLIP OUR FORECAST AREA. WEAK DISTURBANCES WILL MOVING THROUGH THE MEAN FLOW FRIDAY INTO SATURDAY...BRINGING SMALL CHANCES FOR LIGHT SNOW. DID LOWER TEMPERATURES A FEW DEGREES AT THE END OF NEXT WEEK AS GFS/ECMWF INDICATED A CHUNK OF ARCTIC AIR MOVING ALONG THE CANADIAN BORDER. && .AVIATION...SNOW WILL BE A LITTLE SLOWER TO ARRIVE THIS MORNING THAN PREVIOUSLY THOUGHT...BUT CONDITIONS ARE STILL EXPECTED TO RAPIDLY DETERIORATE FROM SW TO NE DURING THE LATE MORNING AND EARLY AFTERNOON. LOOK FOR MVFR/IFR CIGS...AND VSBYS DROPPING TO 1/2SM-1SM IN MOST PLACES. LOCALLY HEAVY SNOW IS EXPECTED THIS AFTERNOON AND EVENING. THERE IS A SMALL THREAT OF FREEZING RAIN SOUTH OF A LINE FROM ISW TO MTW TONIGHT. STRONG GUSTY NE WINDS IN THE FOX VALLEY/LKSHR AREAS WILL CAUSE EXTENSIVE BLOWING AND DRIFTING SNOW. && .MARINE...UPGRADED THE GALE WATCH TO A WARNING FROM 21Z/SUN TO 21Z/MON. NE WINDS WILL INCREASE AS LOW PRESSURE MOVES FROM SOUTHERN IOWA INTO CENTRAL IL TONIGHT...WITH GUSTS EXCEEDING GALE FORCE FOR AN EXTENDED PERIOD. && .GRB WATCHES/WARNINGS/ADVISORIES...
