The morning storms moved very fast from west to east during the early pre-dawn hours...so they didn't block moisture from moving north and they were out of the area shortly after sunrise.I'm not comparing in any way, but what happened 4/27/11 that allowed for both morning and afternoon tornadoes? Would typically think that after the morning convection, that would have stabilized things for the afternoon. But as we all know, that didn't happen.....
