Palm Sunday Weather History

The following weather events affected southeast Minnesota, northeast Iowa, and western Wisconsin on Palm Sunday:

• In 1942 (March 29), 6 inches of snow fell in Viroqua, WI fell.
• In 1951, heavy snow began to fall on March 17th and continued into March 18th (Palm Sunday).  This snow was accompanied by high winds delayed traffic seriously. Many side roads and a number of main roads and highways were blocked by huge drifts.  Many automobiles and trains were stalled, travelers were stranded, and schools closed.  In Minnesota, one death and a number of personal injuries were reported as a result of accidents, etc. during the storm which assumed near-blizzard properties in some localities.  Some snow amounts included:
  • In IA: Cresco (10"), Osage (10"), New Hampton (8"), Dorchester (6"), and Waukon (6").
  • In MN: Harmony (12"), Spring Grove (12"), Winona (11"), Minnesota City (10"), Theilman (9.1"), Grand Meadow (9"), Lake City (8.5"), Austin (8"), La Crescent (8"), Rochester (7.1"), and Caledonia (7").
  • In WI: Hatfield (15"), Mondovi (11.3"), Mather (9"), Alma (8"), Trempealeau (7.5"), Galesville (7"), Neillsville (7"), Owen (6"), Sparta (6"), and West Salem (6").
     
• On Palm Sunday 1965 (April 11), at least one barn was totally destroyed as a very narrow F2 tornado tracked northeast across Crawford County, WI from 3 miles south of Gays Mills to 4 miles east of Soldiers Grove.  Another F2 touched down 4.5 miles west of Tomah, WI, destroying sheds and barns on a farm.  Also, an F1 tornado touched down in Chickasaw County, IA.  None of these tornadoes caused any injuries or deaths.  These tornadoes were part of the Palm Sunday Outbreak (April 11-12) which was the second most damaging outbreak of the 20th century.  During this outbreak, nearly 50 tornadoes struck parts of the Great Lakes region from Wisconsin and Illinois eastward through Lower Michigan and northern Ohio.  The outbreak resulted in 256 deaths and 3,402 injuries.
   
   

• In 1983, an intense low pressure system produced heavy snow in the Midwest from Friday evening (March 25th) through Palm Sunday (March 27th) morning.  Snow depths were highly variable due to the fact that convective activity caused many locally heavy amounts.  The snow combined with strong winds, severely reduced visibilities and produced terrible driving conditions. In western and northern Iowa, the main storm damage of the storm was to trees and power lines.  The wet accumulation downed many branches and tree limbs as well as power lines, damaging houses and resulting in electrical power loss to tens of thousands of homes and businesses.  Most power outages only lasted a few hours, but some homes in rural areas were without electricity for up to 2 days.  WHO-TV in Des Moines was off for two hours due to transmitter trouble and several radio stations were off the air due to the storm.  Three buildings (one in Creston, one in Collins, and one in Lake View) collapsed due to the weight of snow on the roof.  Locally, both Austin, MN (Mower County) and Marble Rock, IA (Floyd County) received 6 inches of snow, and 6 to 8 inches of snow fell across extreme southern Grant and Lafayette counties.

• In 1985, a late-season snowstorm left a band of wet, heavy snow from eastern Nebraska to the Upper Peninsula of Michigan on March 30th and March 31st (Palm Sunday). Some of the heaviest snowfall, up to 16 inches, was reported in the urban areas of Minneapolis-St. Paul, MN.
  
  In Iowa, the heaviest accumulation (about 10") occurred in west-central Iowa and more than six inches fell from Hawarden to Glenwood, northeast to Estherville and Waukon.  Travel became treacherous.  The following snow totals were reported in northeast Iowa:  Decorah (7.5"), Cresco (6"), Dorchester (6"), New Hampton (6"), and Osage (6").
  
  In Minnesota, the snow spread into southern Minnesota during the evening of March 30th.  The snow initially melted as it fell, but by 1:30 AM on the morning of March 31st (Palm Sunday), 6 inches of snow had accumulated in Nobles County in southwest Minnesota.  Snow accumulations increased during the morning of March 31st and reached 6 to 10 inches south of a line from Redwood Falls to just south of Duluth.  Winds of 30 to 40 miles per hour caused some blowing and drifting snow. Additional snowfall became light after mid-afternoon on March 31st.  The following snow totals were reported in southeast Minnesota: Lake City (9"), Rochester (7.4"), Austin (7"), and Harmony (7").
  
  In Wisconsin, the storm brought heavy snow to the north and west sections while the south and east received periods of freezing rain and sleet.  Between 6 and 14 inches of heavy wet snow fell mainly north of a line from La Farge in Vernon County to Iron Mountain, Michigan. Fourteen inches were noted at Lake Thompson in Oneida county and 13 inches were deposited at Baldwin in St. Croix County.  Brisk northwest winds caused considerable blowing and drifting snow which quickly closed several highways and impeded plowing operations.  In the south and east, freezing rain coated many power lines and trees, causing numerous power outages.  Roadways were also ice-covered and sleet fell in many areas, causing next to impossible driving conditions.  The following snow totals were reported in western Wisconsin: Jump River (11"), Mondovi (8"), Caledonia (6"), Cashton (6"), and Genoa (6").

• In 1995 (April 9), a quick-hitting convective snowstorm stuck southwest and central Wisconsin with thunder, lightning, extremely large snowflakes, and sleet.  The event began in the evening and continued into the early morning hours of the 10th. The width of the heavy snow band was only 20 miles extending from La Crosse to Wisconsin Dells to Green Lake.  At the height of the storm, visibilities were near zero.  Some accumulations include: Wisconsin Dells (12"), La Crosse (8"), La Farge (8"), Stoddard (8"), and Yuba (6").
• In 2022 (April 10), southeast winds gusted into the 30 to 50 mph range. The highest winds were 45 mph near Dexter, MN; 46 mph at Rochester International Airport, and 49 mph at Oelwein Municipal Airport.
