Summer storm season often brings large complexes of severe thunderstorms that overspread large areas. Such was the case on Thursday, June 15th. Thunderstorms developed near Hays and expanded south and east through the afternoon and evening. By early morning the 16th, they had exited the state after creating much chaos, especially in the middle of Kansas. Numerous wind reports in excess of 70 mph, isolated heavy rains, and hail up to the size of softballs were reported.
The Kansas Mesonet (mesonet.ksu.edu) provided an ample method of sampling winds associated with this complex. The highest gusts recorded on the network and associated maps:
Hays: 77.4 mph (1500 CDT)
Lorraine: 64.1 mph (1745 CDT)
Gypsum: 63.1 mph (1735 CDT)
Hutchinson 10SW: 59.3 mph (1900 CDT)
Lake City: 58.1 mph (1905 CDT)
Numerous reports of wind damage were also received by the National Weather Service. Many were downed trees, but some structures were impacted. Some potential impacts to agriculture included windblown crops, damage to pivots, and destroyed storage structures. The most impacted region was central Kansas.
Hail was also an issue. The largest report of hail was 4” (roughly softball sized) near Kiowa in south central Kansas. Numerous other reports were spread across central Kansas. When combined with the strong winds, hail can be increasingly damaging, especially to crops. Here are the hail reports on June 15th:
However, not all the weather was negative. These storms brought much needed moisture to central Kansas. A corridor from Hutchinson northeast to Manhattan were on a 14-20 day streak without receiving 0.1” or more of moisture. With the hot and windy weather during this period, the ground was beginning to quickly dry out. This drying was beginning to not only dry the grasses (several grass fires were reported due to lightning with this event) but also not optimal for crops either.
Heavy rains were hit/miss but a large swath of central to eastern Kansas had very beneficial rains. Cut offs between areas of heavy and light-to-no rain were sharp, especially around Hays and Wichita. Below is the map of the total rain measured ending at 7 a.m. June 16th:
Lastly, storms also had a pretty side to them! Below is a photo by Jason Keller near Eskridge, Kansas on the night of June 15 in advance of the storm.
