SqualL Line Worst is first Most common from multicell storms Right ahead of precipitation Tornadoes are rare Stretch a long ways https://www.youtube.com/watch?v=6jL_Jd5VfrQ “In the whales mouth” Under the shelf cloud Very turbulent air Roll Cloud Type of shelf cloud Rotating on horizontal axis

Shelf cloud develops here Rain cooled air sweeps out in front of the storm https://www.youtube.com/watch?v=4wAdVW_XmkI

In the whale’s mouth Griffith, IN 7/24/16 https://www.youtube.com/watch?v=cuB84RH2dfc https://www.youtube.com/watch?v=WDr4yiL-sKA Griffith, IN 7/24/16

https://www.youtube.com/watch?v=i1rdWjrYG5I Roll Cloud

Gustnado Ground based short lived dust whirl Not connected to the cloud base Usually along the leading edge of the storm https://www.youtube.com/watch?v=8UfDt0ghsHI https://www.youtube.com/watch?v=WnBDruK2VOA

Derecho Widespread long-lived wind storm associated with a band of rapidly moving thunderstorms. Swath of severe winds

Green skies and tornadoes? Doesn’t mean tornadoes will form Green skies happen due the hail interacting with the sunlight Green skies = hail

Flash floods NOT considered severe 12” of rushing water can move ANY vehicle Often kill more people than severe weather https://www.youtube.com/watch?v=HxIRLH7fHUI
