I'm not kidding -- I've watched on radar as storms split in half and dodge the area completely. Of course there are also things like tornadoes, the dissipated ends of hurricanes that occasionally wash up the Mississippi valley as if they're trying to cool off by going to Minneapolis and inexplicable 100 knot straight line winds on nearly clear days.
Even the odd earthquake as the Madrid Fault that underlies St. Louis rumbles and shakes and everyone pretends that it won't lay waste to the place when it all finally cuts loose:

Still...all in all...pretty unremarkable (at least to a midwesterner).
But why mess around? This is a fucking weather report: http://en.vedur.is/#tab=skjalftar
