UPDATE: National Weather Service now reports this supercell produced two EF1 tornadoes: http://wgntv.com/2017/06/29/nws-survey-team-identifies-two-tornadoes-southeast-of-rockford-during-wednesday-nights-storms/ All of my video footage as this supercell passed over Huntley, Illinois. It set off tornado sirens in Rockford and Belvidere with numerous funnel clouds spotted with a rotating wall cloud. Here is the National Weather Service Report overview of the June 28th weather event: Wednesday evening, June 28, saw strong to severe storms redevelop and track across far northern Illinois. Some of the initial storms were supercells, bringing low-level rotation and a tornado threat to parts of Winnebago and Boone Counties. There were also areas of straight-line wind damage, including into Lake County Illinois. The main story though was the significant flash flooding in Winnebago and Boone Counties due to 3 to 6+ inches of rain, mainly in less than four hours. The flash flooding was extreme enough to cause dozens of roads to be flooded and impassable across the two counties, include parts of the cities of Rockford and Belvidere. There were reports from Emergency Management of numerous vehicles stranded and drivers having to be rescued, as well as creeks over their banks including Kent Creek in Rockford. Prior to the event, the NWS had been noting potential for heavy rain in Weather Story graphics for a few days in advance, and had issued a Flash Flood watch early Wednesday evening. This was shortly followed by a Flash Flood Warning at 8:24 p.m., updated to a Flash Flood Emergency at 9:32 p.m. given the flooding magnitude.
Waiting at AMERICOLD to get loaded when tornado sirens went off. 30 minutes later one passed us a few miles away.
Contact email@example.com to license. Several tornadoes ravaged parts of Illinois on Thursday, April 9th 2015. Chad Cowan of Live Storms Media intercepted his first tornado just southeast of Rockford and more later in the evening near Belivdere, Illinois. You can see parts of the roof of homes flying with other debris evident in the first tornado. Later in the piece....transformers explode as a tornado strikes a structure causing it to explode and go airborne near the end of the clip.
Was out in front of an MCS plowing through Rockford on I-90 when it re-organized into a Supercell and was tornado warned. Stopped on the side of the road only to see a rapidly rotating wall cloud just to my west produce a fairly large funnel. No direct indication of it making it to the ground, only a damage survey will be able to confirm it. EDIT: This was confirmed as an EF-1 Tornado by the National Weather Service. http://www.weather.gov/images/lot/pastevents/2017/Jun28/Track%20%231.jpg
