Hi John--I'm concerned that, outside our immediate area, news media seem to be referring to last Friday's weather events as just a series of tornadoes and thunderstorms--i.e., more of the same. I've lived nearly all my life in the Midwest, but Friday was the first time I'd experienced anything like that sustained high wind following a lull and a thunderstorm. I don't care if it's called a "land hurricane" or whatever, people need to know this is different and be prepared. Otherwise, we'll have more schools letting kids return to class--just as the high winds hit the school, and other dangerous behaviors. For whatever reason, this was different than our usual spring weather! People need to acknowledge that and be prepared in case it occurs again.
Ida, I agree that people need to be prepared. The entire time the line of thunderstorms were moving through, we continued to warn people to watch out for the second wave of thunderstorms/wind.However, I would have to respectfully somewhat disagree. Derecho's are not unusual. One happened a week and a half before Friday's storm. (The storm that damaged the Dallas Cowboy's training facility.) A couple years ago we had another move through Texas/Louisiana.What brought the highers winds in during the second wave was a bookend vorticy that developed and slid behind the initial wave of thunderstorms. Bookend vorticies happen quite often with bowing line segments. That is why we look for them, as they can often develop quick spin up tornadoes.So in a sense, it is a "usual" spring. May ranks #1 for severe weather around here. April is #2.
