This late Thursday afternoon and evening, primarily between 6 and 10 PM CDT, featured a fairly widespread damaging wind event as a quasi-linear mesoscale convective system (MCS) rolled southeast across nearly the entire six-county area. Although damage was not overly significant and storm reports were limited, automated airport sensors in or near Phillipsburg, Stockton, Smith Center and Beloit measured peak gusts between 58-63 MPH. In addition, a patio roof was torn off in Logan. Hail was not a major issue with these storms, with the largest reported hail only penny size in Burr Oak. Rainfall-wise, much of the area tallied over 1 inch but the highest totals in excess of 3 inches focused across parts of Jewell and Mitchell Counties, including 3.37 inches at Burr Oak. Despite this heavy rain, there were no reports of significant flooding.
Breaking down event timing, the initial development between 6 PM and 730 PM CDT occurred in two separate areas, with one storm cluster pushing in from the west across Phillips, Rooks and Smith Counties, while other storms built south into Jewell County out of Nebraska. Then between 730 and 9 PM CDT, these separate clusters merged into a nearly solid line, with the main part of the line exiting the local area out of Osborne and Mitchell Counties by 930 PM CDT.  Although additional storms lingered over parts of the area past midnight CDT, none were severe. These North Central Kansas storms evolved out of earlier severe storms that developed across southern Nebraska during the afternoon hours along a slow-moving cold front. In the mid and upper levels, synoptic scale forcing was relatively weak, with the area positioned well south of a stronger shortwave trough swinging across southern Canada and the Dakotas. However, with surface dewpoints averaging well into the 60s F, convective instability was quite high with early evening mixed-layer CAPE climbing to at least 2000-3000 J/kg. On the other hand, 0-6 kilometer vertical wind shear was fairly weak at only around 30 knots, which allowed initially slow-moving storms to congeal into a line and surge southeast along strong outflow. Locally heavy rainfall was enhanced by precipitable water values averaging 1.4 to 1.8 inches.
