The National Weather Service says clouds will be on the increase this (Monday) evening, leading to scattered showers and thunderstorms tonight into Tuesday, with lesser chances lingering into Wednesday and Thursday. A few of the storms may be strong to severe by Tuesday with large hail the main threat. Some may also produce locally heavy rains, but likely not of sufficient duration to produce additional flooding. After a break late Thursday or Friday, additional chances for showers and storms return to the forecast over the weekend. There is a better potential for heavy rain which may lead to flooding by this time, but relegated to far southern Iowa and into Missouri.
