 High pressure building in out of Alberta, Saskatchewan. That'll drop some very cool weather down into the region. But you'll notice there's some rain up there. This is light rain, but there is a little upper level disturbance. That will settle in and not do this. Big storms left over the remnants of our weather last night. This is probably going to be much worse in southern Iowa, northwest Illinois, over towards Chicago or south of there over the next few hours. Some nasty storms.
