Let's see: What are my plans tonight? :?:

Oh, yeah, the weather! :eek:

Well best of luck with the cameras in Omaha. We got tornado warnings near Columbus, Nebraska just west of Omaha. New supercells are exploding along the stationary front. Strong/violent tornadoes, hail to softball sized, wind gusts to 80 mph, and flooding rains will all be a likely threat this evening including in Omaha.
