There will be two chances of thunderstorms over the area on Friday into Saturday morning. The first round currently over northern Missouri is producing frequent lighting, small hail, heavy rain, and localized flooding. These storms will continue to the east and dissipate in the early afternoon. A second round of storms is expected to form along the Missouri/Iowa border towards the late afternoon and continue to develop in this region throughout the night. The greatest threat of severe weather appears to be north of the Iowa border, but a few storms may push down into Missouri overnight with large hail and damaging winds possible in this area. Here’s the 7-day forecast from the National Weather Service:
