Very impressive radar returns just west of Omaha, Neb.
Many easterners may remember the derecho that took place across the mid-atlantic in June 2012. Hurricane force winds and intense tornadoes are forecasted. The severe threat moves east for Wednesday, but a derecho is not expected. However, strong to severe thunderstorms should cause no surprise.
Convection outlook for midwest tonight
Day 2 convection outlook (for east)
