Several damaging thunderstorms raked across portions of north central Kansas on this Thursday afternoon and evening. A small multicell cluster of thunderstorms developed along the Nebraska-Kansas state line and began moving into western Phillips County just before 3 p.m. CST. The leading storm intensified and became a supercell. This cluster moved southeast across portions of Rooks and Osborne counties through 5:30 p.m. CST, continuing to be anchored by the supercell. This supercell produced prolific amounts of hail along its path, covering the ground in some areas. The largest reported was the size of baseballs near the town of Speed, in Phillips County. Significant damage occurred to the roof, siding, windows, and several vehicles on one farm. Radar signatures strongly suggested this storm may have produced hail of similar size in other areas, but no reports were received due to low population. This storm also damaged trees in southwest Osborne County. Between 5 and 6 p.m. CST, a broken line of thunderstorms dropped out of Nebraska into north central Kansas. A couple of these storms were severe as well. One was a supercell that tracked through Phillips and Osborne counties, a little north of the previous storm. This storm produced hail to at least the size of golf balls. The other storm raked across Jewell county between 5:30 and 6:30 p.m. CST. This storm was responsible for multiple reports of measured winds in excess of 65 MPH, including one of 80 MPH. Hail was reported up to 1.5 inches in diameter. Wind driven hail broken windows in some homes on the north side of the town of Jewell.
These storms formed along and head of a strong Canadian cold front. In the upper-levels, a trough was over the central United States, and an embedded shortwave trough was moving into the Central Plains. In the pre-storm environment, surface temperatures were in the lower 90s, with dewpoints in the 50s. Combined with mid-level lapse rates were near 7 degrees C/km, resultant MLCAPE was around 2000 J/kg. Deep layer shear was 35-45 knots, with 0-3 km SRH 100-200 m2/s2.
