Several reports of dime to penny size hail were relayed by local media and a trained spotter.
This Monday featured a rare, albeit brief morning tornado that destroyed a 30 x 40 foot machine shed on a farm 9 miles east of Mankato along Highway 36. This short-track EF0 tornado struck shortly before sunrise and just before 7 AM CDT, during one of the climatologically least-favored times of day for tornadoes to occur in North Central Kansas. This tornado was the only known occurrence of severe weather associated with this event.
Storms first entered this six-county portion of North Central Kansas from the south between 530 and 6 AM CDT, initially organized in a quasi-linear mode along the leading edge of a weakening squall line. However, between 6 and 7 AM CDT, a few storms along the far northeast edge of this advancing line intensified and became semi-discrete as they tracked north-northeast at 45-55 MPH across parts of Mitchell and Jewell Counties. It was one of these semi-discrete storms that abruptly assumed brief rotation per radar reflectivity and velocity data as it crossed the Highway 36 corridor east of Mankato, corresponding to the tornado damage report. By 730 AM CDT, this small cluster of semi-discrete storms exited northward into south central Nebraska, with no further reports of severe weather.
Although the synoptic scale setup did not necessarily suggest the likelihood of early morning tornadic development, the mesoscale environment revealed a moist low level airmass, very strong low level shear, and sufficient instability with 0-1 kilometer mixed layer CAPE around 1000 J/kg. Around the time of tornado occurrence, nearby surface observations revealed an approximate surface temperature/dewpoint of 65/59, in the presence of very strong 0-1 kilometer low level shear near 40 knots and 0-1 kilometer storm relative helicity of 200-300 m2/s2. On the larger scale, this event occurred within a broad surface warm sector, well to the east of a cold front oriented north-south across western Kansas. This expansive cold front stretched from the Dakotas to Mexico, and was anchored by a deep surface low centered near the MT/ND border. In the mid and upper levels, a highly amplified and expansive trough was situated over the western half of the CONUS. On the prior evening of the 18th, this system had spawned several tornadoes near North Platte, Nebraska.
