A FLASH FLOOD WATCH will go into effect at 3am and will last through much of Thursday morning.
Widespread thunderstorms are forecast to develop over southwest Iowa and spread northeast overnight tonight into Thursday morning. Moderate to locally heavy rainfall totals are anticipated by midday Thursday where a widespread 1 to 2 inches will be common and certainly cannot rule out locally higher amounts up to 3 inches. The strongest thunderstorms may produce 1 to 2 inch rainfall rates on top of an already very saturated ground.
A flash flood watch means that conditions may develop that lead to flash flooding. Flash flooding is a very dangerous situation. Remember to turn around, don’t drown.
