The episode as NWS MPX wrote it up.
A strong late Winter and early Spring storm produced two areas of heavy snowfall across southern Minnesota, and into west central Wisconsin during the afternoon of March 23rd, through early morning of March 24th.
The first band of heavy snowfall developed between Springfield to New Ulm, northeast across the southern part of the Twin Cities Metro area, into portions of west central Wisconsin near River Falls. Initially, this band was disorganized but became a solid enhanced band for several hours during the afternoon. Snowfall rates in this band ranged from 1/2 to locally 2 inches per hour. Due to very dry air on the northern edge of this band, snowfall amounts cutoff dramatically from over a foot, to only a few inches within 20 miles. This band quickly dissipated during the evening and ended before midnight. However, before the snowfall ended, locally 8 to 12 inches of snow fell in a band from near Prior Lake, east-northeast to Savage, Eagan and Cottage Grove. Outside of these amounts, 6 to 8 inches of snowfall was common before it ended during the evening.
As the northern band began to dissipate, a secondary area of snowfall developed across northern Iowa, and moved into southern Minnesota during the late evening, and early morning hours of Thursday March, 24th. A band of heavier snowfall developed between Fairmont, Owatonna, and Red Wing, Minnesota, and slowly moved south during the pre-dawn hours. This secondary band had snowfall rates as high as 1 to 2 inches per hour which caused an area of 8 to 12 inches from south of Fairmont, northeast to Ellendale, and the southern part of Steele county.
The following are some of the heavier snowfall totals from this storm.
12.00 inches in Savage, MN|12.00 inches in Apple Valley, MN|11.50 inches in Burnsville, MN|11.00 inches north of Henderson, MN|11.00 inches south of Lakeville, MN|11.00 inches west of Rosemount, MN|11.00 inches northeast of Lakeville, MN|11.00 inches in Ellendale, MN|10.70 inches in New Prague, MN|10.00 inches in Prior Lake, MN|10.00 inches in Cottage Grove, MN|10.00 inches south of Owatonna, MN.

THE SHORT CONCERN IS RESOLUTION OF HEADLINES FOR THE EVENT.
MODELS ARE NOW IN FAIR AGREEMENT NOW WITH SYSTEM LIFTING NORTHEAST
WITH SURFACE LOW TRACK NOW CLOSE TO A KANSAS CITY AT 00Z/24 TO
SOUTHEAST IOWA BY 12Z/24 AND THROUGH CHICAGO REGION THURSDAY
MORNING. THIS TRACK FAVORS A MORE SOUTHERN HEAVY SNOW BAND...AND
WILL RESOLVE THE METRO AREA WATCH WITH AN ADVISORY. GRADIENT LIES
OVER THE 7 COUNTY AREA...WITH A DUSTING IN THE MOST OF ANOKA COUNTY
TO NEAR 8 INCHES IN FAR SOUTHERN DAKOTA COUNTY. THE 00Z GFS
REMAINED THE FARTHEST NORTH WITH THE SNOW AREA...WITH THE OTHER
EVENING DETERMINISTIC MODELS TRAILING SNOW OFF RAPIDLY OVER THE
METRO INTO NW WISCONSIN.
FORCING WISE...THERE WILL BE A MORNING FGEN BAND OVER SOUTHWEST
MN...LIFTING RAPIDLY TO THE METRO BY 15Z-16Z. THIS REMAINS OVER THE
AREA DURING THE DAY AND EVENTUALLY SHIFTS SOUTHEAST. BETWEEN 00Z-06Z
THE UPPER LOW AND MID LEVEL TROUGH DROPS TO THE SOUTHEAST OF MUCH OF
CENTRAL AND SOUTHWEST MN AND SHOULD GRADUALLY TAPER THE SNOW. THE
HEAVY SNOW REDEVELOPS OVER SOUTHEAST MN INTO A PORTION OF WEST
CENTRAL WI...WHERE UP TO A FOOT OF SNOW IS POSSIBLE....FROM
ROCHESTER NEAR AUGUSTA/SOUTH OF EAU CLAIRE IN WEST CENTRAL WISCONSIN.
THE NORTHEAST WIND IS EXPECTED TO INCREASE AS WELL DURING THE
AFTERNOON...AND WILL LIKELY CAUSE SIGNIFICANT BLOWING/DRIFTING ONCE
THE SNOW ACCUMULATES. IT WILL BE A HEAVIER/WETTER SNOW...SO IT WILL
BE DIFFICULT TO DRIFT AT THE ONSET. WIND GUSTS OF 35-40 MPH WILL
GENERATE NEAR BLIZZARD CONDITIONS...ESPECIALLY ALONG I90 LATE
AFTERNOON/EVENING.
THE SNOW SHOULD END OVER THE MN PORTION OF THE AREA THROUGH ABOUT
12Z THU. IT WILL LIKELY LINGER IN A PART OF WEST CENTRAL WISCONSIN
THROUGH 14Z.

MUCH OF THE AREA IN THE SHORT TERM...SURFACE HIGH PRESSURE WILL
BRIEFLY BUILD IN FOR THURSDAY NIGHT...BUT RETURN FLOW ALREADY
BECOMES ESTABLISHED BY FRIDAY AS THE NEXT TROUGH APPROACHES.
HIGHS WILL REBOUND BACK INTO THE 40S AS A RESULT...WHICH WILL MEAN
PROGRESS IN THE SNOW MELTING DEPARTMENT. GIVEN THE WARM THERMAL
PROFILES...THE SYSTEM FOR FRIDAY NIGHT AND SATURDAY LOOKS TO BE
MIXED PRECIP...WITH MAINLY RAIN DURING THE DAYTIME AND SNOW DURING
THE NOCTURNAL TIMEFRAMES. THIS SHOULD MINIMIZE THE THREAT FOR
NOTABLE SNOWFALL ACCUMS.
BEHIND THE SECONDARY SYSTEM...TEMPERATURES WILL MODERATE BACK
ABOVE NORMAL...WITH HIGHS IN THE UPPER 40S TO MID 50S EXPECTED FOR
TUESDAY.
