The storm was expected to impact areas near Westplains and North Sterling Reservoir.

A second warning followed just five minutes later at 3:30 p.m. for another storm system impacting northeastern Weld County. That storm, moving north at 20 miles per hour, was located along a line stretching from northwest of Briggsdale to north of Stoneham.
