A cold front that swept across the Central Plains beginning Sunday afternoon. Showers and thunderstorms developed out ahead of the boundary in the warm, moist flow regime, mainly across eastern Kansas and western Missouri. Showers and a few rumbles of thunder also developed along and behind the boundary. Rainfall totals across the region were generally in the half inch to one inch range, but a few locations saw 2 to 3 inches or more of rain over the course of the event.
The frontal passage also brought cooler, drier air into eastern Kansas. Afternoon high temperatures Monday were approximately 10 degrees cooler than those observed Sunday. At Topeka on Sunday, the high temperature was 87 degrees, while Monday recorded a high of 76. At Manhattan, the high Sunday was 90 degrees, while Monday saw a high of 72 degrees. Also of note were the much cooler dewpoint temperatures observed Monday, which made for a less muggy, and much more comfortable afternoon.
