Episode narrative: A squall line developed over southeast Missouri and moved rapidly east-southeast across western Kentucky. Areas along and southwest of a line from Hopkinsville to Princeton to Smithland received widespread strong winds. Locally damaging winds occurred, especially from Ballard County southeast across the Paducah, Mayfield, and Kentucky Lake regions to Hopkinsville. The bow-shaped squall line formed from a cluster of thunderstorms over central Missouri during the late morning hours. South of a surface front that extended from central Missouri to the I-64 corridor of southern Illinois, rapid heating of a moist air mass produced strong instability. Mixed layer cape values climbed above 3000 j/kg. A core of strong mid-level winds from 50 to 60 knots in the vicinity of the storms aided in rapid propagation and organization of the storms across western Kentucky.

Episode narrative: Long duration severe weather event across the northeast plains, and most of the Denver metropolitan area beginning during the early afternoon hours.   Scores of  tornadoes occurred across Washington and Logan counties.  Several rounds of hail across the Denver metro, with ping pong ball sized hail in downtown, larger hail up to 2 inches in diameter at concert in Red Rocks Amphitheatre.  In all, seven patrons were hospitalized,  with 83 treated on scene.   A substantial number of attendees suffered welts, bruises and broken fingers trying to protect themselves.  Several suffered concussions as well.  A total of 33 tornadoes touched down in Washington County, with 3 reported in Logan County.  There were reports of at least one home damaged west of Sterling and one commercial building collapse in Sterling. The home was damaged by one of the tornadoes.

Significant flooding and flash flooding also occurred in portions of the plains, including Elbert, Arapahoe, Adams, Logan, Washington and Morgan counties. There were likely several rural roads that flooded due to the heavy rainfall.  There was a flood fatality just south of I-70 along Watkins Rd.  First responders found two stranded cars swept into a field, but its occupants had either gotten out or had been rescued. The third vehicle ended up west of Watkins and 6th Ave. in what is normally a dry creek bed. South Metroï¿½ï¿½ï¿½s water rescue team was then called out to do a water rescue but that operation turned into a recovery by the following morning.  Due to flooding, Watkins Road was closed between Interstate 70 and Jewell Ave.  Interstate 70 was also closed for several hours until water could recede from flooded underpasses. Minor flooding also occurred in portions of the Denver and the surrounding metro area.  Baseball size hail was observed in Washington County.

The tornado crawled through open country toward the north-northwest for several minutes and crossed Beaver Creek before damaging several trees on a farmstead along 425th Avenue. The tornado also ripped tin off an abandoned outbuilding. At this point, the tornado track veered to the north as it moved through soybean fields and across 301st Street before it lifted around a tenth of a mile north of 301st Street. The average path width for the tornado was 30 yards. The tornado was rated an EF-0 with a maximum estimated wind gust of 74 mph.
Episode narrative: Very hot and humid air in place across eastern Iowa, northwest Illinois, and far northeast Missouri interacted with a southward moving frontal boundary and disturbance aloft, setting the stage for development and organization of severe thunderstorms across the region. Storms initially formed from north central Iowa and southern Wisconsin along the frontal boundary, which slowly worked south into the hot, humid air in place across the region. As storms arrived across east central Iowa, they began producing winds around 70 MPH across the Hwy 20 corridor. Another storm to the south further intensified, and began producing winds of 80+ MPH as it tracked along the Hwy 30 corridor. This impacted the northern suburbs of Cedar Rapids into Clinton. These storms continued to produce wind gusts around 60-70 MPH as they progressed into northwest Illinois. One brief EF-0 tornado began in Clinton, Iowa, then moved across the Mississippi River before dissipating near Fulton, Illinois. Damage near Andrew, Iowa in Jackson County was determined to be straight-line winds. Storms additionally produced large hail around the Dubuque metro, with quarter size hail reported.

Episode narrative: Southerly upper level winds moved across Nebraska and brought in a thick layer of low-level stratus clouds during the early morning hours. These clouds limited surface heating during the day; however, cooler air aloft moved over the area during midday. These conditions resulted in more instability. This instability combined with a low-pressure system, forcing from a strong 500 mb jet, and strong low-level wind shear. There was locally enhanced 0 ï¿½ï¿½ï¿½ 1 km helicity near a surface low. There was an intersection of a surface warm front with a dryline and cold front near the center of the surface low. The cold front moved across the area during the overnight hours. These conditions resulted in severe weather during the afternoon hours. 

Thunderstorms were present across Nebraska during the early afternoon hours and moved northeastward. These storms began in south central Nebraska by producing a tornado in Phelps County at 1:05 PM CDT. This tornado was rated as an EF-0 and did some damage. These storms moved eastward and developed into line segments and went on to produce 5 more tornadoes. The additional tornadoes were in Dawson, Franklin, Kearney, Adams, and Hall Counties. The tornadoes in Franklin and Kearney Counties were rated EF-1 while the others were rated EF-0. These storms also produced hail and severe wind gusts. The biggest hail was half dollar size in Phelps County. There was a 63 mph wind gust in Adams County. The storms ended by producing nickel sized hail in Hamilton County at 5:05 PM CDT.
