Southerly winds have picked up ahead of a weak cold front currently in eastern Iowa. The line of thunderstorms that developed very early this morning in western Iowa have been reduced to nothing more than a few clouds and sprinkles as they move closer to the Mississippi River.
The front will slow and then stall across the area later this afternoon and with little moisture in place storm coverage will be limited. By this evening the front will stall a little south of Rockford as another area of low pressure develops in the Plains. At the same time the low level jet will increase and pull in moisture as it runs into the front. That secondary low will move along the boundary trying to lift it back north as a warm front Thursday afternoon. Scattered showers will be likely along and especially north of the front. Rainfall totals will range from about half an inch up to one and a half inches by Thursday night. The low will pass Friday with showers ending by Friday night.
