What happened
The episode as NWS MKX wrote it up.
A powerful low pressure center, passing south of Wisconsin, produced blizzard conditions across much of southern Wisconsin from the evening hours of Tuesday, February 1st into the early morning of Wednesday, February 2nd. Snow associated with the system began in the mid-afternoon hours of February 1st in far southern Wisconsin and became heavy as it pushed northward into the state through the evening. Very strong winds were associated with this storm for an extended period of time. Sustained winds of 30 to 40 mph were common through the event, with peak wind gusts between 45 and 55 mph. The combination of high winds and heavy snow created whiteout conditions with visibilities falling to near zero. Twenty-four hour snowfall totals were between 14 and 15 inches. In addition to the blizzard, several inches of snow fell on Jan 31. It's possible that some locations did not see a break in snowfall between the evening of January 31st and the morning of February 2nd. Many cooperative observer stations set records for multi-day snowfall totals. Beloit tied a record with a one-day (2/1) snowfall of 15 inches, is tied for second place with two-day (1/31-2/1) total of 17.0 inches and tied for fifth with a three-day (1/31-2/2) snowfall of 17.0 inches. Snow drifts of 3 to 8 feet were common, with reports of some drifts reaching 12 to 15 feet in open rural areas. Many area school districts dismissed classes early on February 1st, and remained closed on the 2nd and 3rd. A Civil Danger Warning was issued by Wisconsin Emergency Management concerning the dangerous driving conditions. Interstate 43 from Beloit to Mukwonago was closed, as well as portions of Interstate 90, with many stranded motorists having to be rescued from vehicles buried in the drifting snow. About 100 National Guardsman were mobilized statewide in response to Gov. Scott Walker's emergency declaration for 29 counties to help rescue motorists and run emergency shelters at armories. Rock County sheriff deputies had to abandoned their squad cars and jump into National Guard Humvees and Army trucks, which also got stuck in the deep drifts. Wisconsin DNR snowmobiles also became stuck in the deep snow. A 66-year old Janesville man was hospitalized for hypothermia after he fell and was subsequently buried by snow from a snow plow before being found by a neighbor a dug out of the snow bank 4 hours later. The blizzard conditions prevented firefighters from reaching a house fire in Gratiot (Lafayette County) until conditions improved enough for a plow to clear the road. The house was a total loss. Alliant energy reported 7,263 customers in the Milton-Edgerton area were without power at the height of the storm.

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE MILWAUKEE/SULLIVAN WI
252 PM CST TUE FEB 1 2011
TONIGHT AND WEDNESDAY- CONFIDENCE...HIGH
BLIZZARD ON TRACK TO CLOBBER THE AREA. CURRENT BLIZZARD/WINTER STORM
HEADLINES LOOK RIGHT ON. INITIAL SURGE OF SNOW MAKING QUICK
PROGRESS INTO THE AREA FROM ILLINOIS...SO GOING START TIMES LOOK
FINE. STRONG UPPER JET COUPLING CENTERED ACROSS SOUTHERN WI. STRONG
500 MILLIBAR VORT CENTER TRACKS FROM NEAR ST. LOUIS TO NORTHWEST
INDIANA BY 12Z WEDNESDAY. DRY SLOT RACING NORTH THOUGH EXPECT IT NOT
TO MAKE IT INTO THE AREA...WE WILL REMAIN WITHIN THE DEFORMATION
ZONE...OR LEFT OF THE DRY SLOT. 700-300 MILLIBAR Q-VECTOR
CONVERGENCE EXCEEDS 50 UNITS IN SOUTHEAST WI. NAM SHOWS STRONG 600
MILLIBAR FRONTOGENESIS STRENGTHENING THIS EVENING AND PERSISTING
THOUGH 9Z.
NAM HAS UPPED QPF TOTALS INTO SOUTHERN WI IN LINE WITH
00Z AND 12Z ECMWF NUMBERS...AROUND 1.25 INCHES IN SE WI. GFS LESS
ROBUST. IMPRESSIVELY DEEP DENDRITE GROWTH ZONE IS A WHOPPING 13000
FEET BETWEEN 11 PM AND 4 AM...THIS COULD LEAD TO SOME VERY
IMPRESSIVE HOURLY SNOWFALL RATES. RATIOS KEY...AND AGAIN LEANED
TOWARDS THE LOWER ROEBBER VALUES...WHICH HANDLES WIND CONSIDERATIONS
BETTER THAN THE COBB TECHNIQUE. HOWEVER ADDITIVE FEATURES TO THE
EVENTUAL TOTALS INCLUDE THE LAKE CONTRIBUTION...WHICH PERSISTS FOR
THE DURATION OF THE EVENT. ALSO SOME POTENTIAL FOR CONVECTION.
NOTICED ON THE WETZEL INGREDIENT PLOTS THAT THERE WAS SOME ELEVATED
INSTABILITY AROUND 500 MILLIBARS...WITH LARGE BULLSYSE OF PVU ACROSS
SOUTHEAST WI. INSTABILITY NOT AS CLEAR CUT ON BUFFY SOUNDINGS THOUGH
THUNDER ALREADY REPORTED IN MISSOURI. SPC DAY 1 OUTLOOK BRINGS SOME
THUNDER POTENTIAL INTO THE FAR SOUTHEAST AS WELL. STRONG NORTHEAST
850 MILLIBAR LOW LEVEL JET OF 50-60 KNOTS WRAPS AROUND THE TIGHTLY
WOUND LOW CENTER...WITH 50 KNOTS AS LOW AS 925 MILLIBARS. WE WILL
SEE SOME OF THESE 50 KNOTS GUSTS MIXING DOWN TO THE SURFACE WITH LOW
LEVEL INSTABILITY TAPPING INTO THESE STRONGER WINDS.
THE LAKE EFFECT FLOWCHART SUGGESTS MODERATE TO HEAVY ADDITIONAL
TOTALS TO THE SYNOPTIC EVENT ITSELF...SO BOOSTED AMOUNTS EVEN MORE
LAKESIDE. FEEL THE ONGOING INLAND CONVERGENCE WILL REFOCUS MORE
TOWARDS THE LAKESHORE COUNTIES AS THE 1000-850 MILLIBAR SHIFTS
MORE TOWARDS THE NORTH...ESPECIALLY WEDNESDAY MORNING. NAM SHOWS
1000-850 CONVERGENCE BULLSYE FROM MILWAUKEE TO KENOSHA BETWEEN 12Z
AND 15Z. HAVE USED A BLEND OF THE 12Z GFS/ECMWF QPF. HAVE TOTALS
OF 13-16 INCH IN THE FAR SOUTHEAST WITH MUCH LESSER TOTALS IN THE
FAR NORTHWEST...BUT WINDS THERE WILL STILL MAKE IT A WINTER STORM.
PLACEMENT OF PRIMARY LAKE EFFECT BAND WILL POTENTIALLY ENHANCE
TOTALS EVEN MORE FROM MILWAUKEE SOUTH.
BRUNT OF THE SNOW WILL WIND DOWN BY 15Z...9 AM...WITH THE STRONGER
Q-VECTOR CONVERGENCE DECREASING AND SHIFTING EAST. LAKE EFFECT
TRAJECTORIES ALSO BECOME LESS FAVORABLE WITH 1000-850 MILLIBAR
CONVERGENCE SHIFTING OFFSHORE AFTER 15Z. GRADIENT WINDS AROUND THE
STRONG LOW WILL REMAIN A CONCERN INTO AT LEAST EARLY AFTERNOON.
.WEDNESDAY NIGHT...FORECAST CONFIDENCE IS HIGH.
SOME CLOUDS LINGER IN THE SOUTHEAST EARLY...OTHERWISE...CLASSIC
CLEAR AND COLD NIGHT IN POST SNOWSTORM ENVIRONMENT. COLD AIR IN
PLACE BY EVENING...BUT TEMPS ABOVE THE BOUNDRY LAYER TRY TO
REBOUND AFTER MIDNIGHT IN BACKING FLOW AHEAD OF NEXT APPROACHING
TROF FROM THE NDORTHWEST. HOWEVER...WITH FRESH SNOW COVER THIS
WARM AIR ADVECTION WILL RIDE OVER THE TOP OF A SHARP BOUNDRY LAYER
INVERSION. TEMPS GENERALLY 0 TO 10 BELOW WITH WIND CHILLS DIPPING
TO 20 TO 30 BELOW. A WIND CHILL ADVISORY WILL LIKELY BE ISSUED
LATER...JUST NOT NOW WITH ALL THE OTHER MAJOR HEADLINES IN EFFECT.
.THURSDAY THROUGH FRIDAY...FORECAST CONFIDENCE IS HIGH.
QUITE THIS PERIOD WITH TEMPS CONTINUING TO SLOWLY MODIFY AS WE GET
ATYPICAL WARM ADVECTION FROM THE NORTHWEST...COMING OUT OF
CANADA...AHEAD OF A DEEPING NORTHWEST TROF. THE COLUMN REMAINS
TOO DRY FOR ANY PRECIP WITH THE ADVECTION...AND IT ISN/T THAT
STRONG TO BEGIN WITH.
.FRIDAY NIGHT AND SATURDAY...FORECAST CONFIDENCE IS MEDIUM.
UPPER LOW CONTINUES TO DIG INTO THE GREAT LAKES AND CLOSES OFF
FRIDAY NIGHT AND SATURDAY...BEFORE OPENING BACK UP AND SHEARING
OFF TO THE EAST BY SUNDAY MORNING. NOT AN IMPRESSIVE AMOUNT OF
MOISTURE WITH THIS SYSTEM...BUT ENOUGH TO HAVE SMALL POPS FOR
LIGHT SNOW AT THIS POINT.
.SUNDAY...FORECAST CONFIDENCE IS MEDIUM.
QUIET AND SEASONABLE UNDER SHORT WAVE RIDGING.
.EARLY NEXT WEEK...FORECAST CONFIDENCE IS MEDIUM.
ANOTHER CLIPPER ARRIVES AND COULD BRING SOME LIGHT SNOW TO THE
AREA. IN THE WAKE OF THIS FAST SYSTEM...TEMPS COLLAPSE AGAIN BY
TUESDAY MORNING WITH BITTER CONDITIONS FORECAST.
&&
.AVIATION...LIGHT TO MODERATE SNOW MOVES IN TO THE TAF SITES LATE THIS
AFTERNOON...BECOMING MODERATE TO HEAVY BY AROUND 00Z. EXPECT LONG
DURATION OF VLIFR VISBYS...FREQUENTLY TO 1/4 MILE...AS A RESULT OF
FALLING SNOW COMBINED WITH BLOWING SNOW. STRONG WINDS GRADUALLY
SHIFT FROM NORTHEAST THIS EVENING...TO NORTH BY MORNING. EXPECT
SUSTAINED WINDS 20 TO 30 KT...WITH GUSTS 35 TO 45 KT. THIS WILL
ALSO LEAD TO WIND SHEAR OF 20 TO 30 KT IN THE LOWEST 2KFT.
CONDITIONS BEGIN TO IMPROVE LATE MORNING AS THE SNOW DECREASES WEST
TO EAST. BLOWING SNOW CONTINUES THROUGH THE MORNING INTO THE EARLY
AFTERNOON WITH WINDS ABOVE 20KT. WINDS DECREASE INTO THE AFTERNOON
WITH IMPROVING GENERAL IMPROVING CONDITIONS.
