Overview
|
A winter storm brought a mix of precipitation to all of eastern Iowa, northwest Illinois and far northeast Missouri beginning on the evening of Feb 16, and ending on the late afternoon of Feb 17. Areas observed rain at first, but saw a transition over to snow by the morning of Feb 17. Snow amounts of 3 to 6 inches were measured on the evening of Feb 17, and were most prevalent in far northeast Missouri and west central Illinois. A few amounts of 7 to 8 inches were observed over far southern McDonough and Hancock counties in Illinois, where snow bands persisted longer. Snow totals decreased to the north and west, where dry air aloft prevented much in the way of northward progression of snow.
