Although numerous thunderstorms rumbled across this six-county North Central Kansas area from the afternoon of Wednesday the 10th into the early morning of Thursday the 11th, the vast majority of them were sub-severe, producing only gusty winds and brief, heavy downpours. Storm mode primarily consisted of multicell clusters and lines, and the only ground-truth severe-criteria report was estimated 60 MPH gusts in northwestern Smith County at 9 p.m. CDT. During the preceding hour, this same small-scale linear complex yielded several reports of near-severe gusts in the 50-55 MPH range across Phillips County. As for rainfall, the majority of the local area only reported modest amounts of 0.50-1.00. However, much of Jewell and Mitchell counties tallied closer to 1.50, with a small section of southeast Jewell and northeast Mitchell, including the Randall area, getting drenched with at least 2.50-3.00. Despite a lack of ground-truth reports, it can be reasonably assumed that there were some short-term flooding issues in this area lasting into the day of the 11th.
As for some timing details, the first few storms of the day initiated over Phillips and Smith counties between 5:45-7:00 p.m. CDT before quickly departing northward into Nebraska. Following a short lull, the next storm cluster marched into Phillips/Rooks counties from the west between 7:45-8:45 p.m. CDT and went on to produce the 60 MPH winds in Smith County. Through the remainder of the night, numerous non-severe storms continued streaming across the area, with most places finally rain-free by 6 a.m. CDT. Turning to the synoptic and mesoscale setup: the primary trigger aloft was a series of fairly subtle disturbances gradually overspreading the Central Plains, out ahead of a modest shortwave trough drifting southeast toward the region from the Northern Rockies. At the surface, the most evident boundary near the local area during the afternoon was a trough axis extending southwestward to weak low pressure centered near the KS/CO border. With afternoon temperatures rising into the mid-upper 90s, storms developed in an environment featuring 1000-2000 J/kg mixed-layer CAPE and around 30 knots of 0-6 kilometer deep layer wind shear. During the night, widespread weak convection persisted within the exit region of a 30-40 knot low level jet.
