While more concentrated swaths of severe weather focused a few counties off to the north and also southwest, small portions of this six-county North Central Kansas area also saw a handful of severe storms on this Tuesday evening. The majority of local activity targeted Phillips and northwestern Smith counties, as a mix of semi-discrete cells and quasi-linear clusters roamed and redeveloped over the area between 7-10 p.m. CDT. These storms were mainly hail-producers, yielding stones to the size of golf balls in Agra, ping pong balls north of Kensington and quarter size in and near Phillipsburg and Speed. Prior to any development in those areas, a lone severe storm drifting north out of central Kansas into southern Osborne County dropped quarter size hail in Natoma shortly before 6:30 p.m. CDT before weakening. Although damaging winds did not seem to be much of an issue, a KSU mesonet site near Tipton measured a 64 MPH gust shortly after 10 p.m. CDT as outflow surged north out of central Kansas along the leading edge of a weakening storm cluster. After this, a smattering of weak convection persisted within the local area for several hours before ending completely by 4 a.m. CDT on the 14th. Rainfall-wise, most of this six-county domain received little if any, but portions of mainly northern Phillips and northwestern Smith counties received at least 1, with radar estimation suggesting a small part of extreme northern Smith County might have had 3.
In the mid-upper levels, this event was driven by a shortwave trough swinging east through the Central Plains, to the southeast of its parent closed low centered over Montana. At the surface, storm initiation clearly focused along a composite stationary front/dryline stretched north-south through central portions of Nebraska and Kansas, attendant to a surface low pressure center that deepened to 998 millibars during the late afternoon hours. To the east of this dryline, afternoon high temperatures into the mid-upper 90s F combined with dewpoints in the upper 50s-mid 60s resulted in mixed-layer CAPE values of at least 2000-3000 J/kg, in the presence of 0-6 kilometer shear increasing to 40-50 knots as the evening progressed.
