The following weather events affected northeast Iowa, southeast Minnesota, and western Wisconsin on Valentine’s Day:

  • In 1896, a strong low pressure system moved through the region. The warm front associated with this system moved through Prairie du Chien, WI during the day.  As a result, the temperature climbed to 58 there.  However, a strong cold front soon followed a few hours later and by midnight, the temperature had fallen to -8.  This 66 degree diurnal temperature change is the greatest ever recorded there.
  • In 1918, Medford, WI received 1.40" of precipitation.  This made it their wettest February day.
  • In 1950, a low pressure system developed over north central Texas during the afternoon of February 12th.  This storm moved slowly northeastward and later northward across northern Arkansas, southeastern Missouri, southern Illinois, Indiana, and Lower Michigan.  By the afternoon of the February 14th, the low pressure area had reached the Straights of Mackinac.  This storm produced the heaviest snowfall of the winter in southern and central Wisconsin, and considerable drifting resulted because of the high winds.  The traffic on many highways was seriously impeded for about 12 hours.  The snow storm produced the following snow totals:
    • In northeast Iowa:  Lansing (8") and Decorah (7.5").
    • In southeast Minnesota:  Elgin (8"), Grand Meadow (8"), La Crescent (8"), Winona (8"), and Caledonia (7.5").
    • In western Wisconsin:  Mauston (8.5"), Alma (8"), Muscoda (7.5"), West Salem (6.2"), and Steuben (6").
