A strong upper level jet pushing across the Rockies resulted in development of low pressure across southeast Colorado late on April 2, which intensified rapidly moving across Kansas and into Illinois on April 3.  A broad swath of snow and gusty winds developed north of the low track across the area, with heaviest snowfall amounts in excess of 6 inches generally corresponding to highest terrain areas in south central and southeast South Dakota, northern portions of northwest Iowa and areas of southwest Minnesota. As unseasonably cold high pressure spread in behind the system on the morning of April 4, a few low temperature records were broken by as much as 5 to 15 degrees.
