Thunderstorms over western Iowa will slowly spread east tonight. These storms will be moving from southwest to northeast ahead of a cold front and will have the potential for several storms to move over the same areas. These storms will also be efficient rainfall producers and this will lead to the potential for heavy rainfall. The region is already quite saturated with numerous streams still in flood and significant ponding already in place. Additional heavy rainfall will lead to flash flooding.
This watch will be in effect from 10PM CDT this evening through Sunday morning. Continue to check back to the Iowa Storm Chasing Network for the latest updates.
