A strong line of storms are expected to move through the state late Tuesday night into Wednesday.

“The storms are expected to just be getting to far western Iowa around 6 p.m. this evening,” State Climatologist Harry Hillaker said. “They list that Creston has a chance for rain as early as 6 p.m., but it is not likely until sunset at the earliest.”

The thunderstorms are expected to bring high winds, heavy rainfall and large hail. The National Weather Service predicts the chance of these storms is 90 percent.

Hillaker said the primary feature of the storm will be the heavy rainfall. The NWS is calling for three to five inches of rain an hour.

A flash flood watch has already been issued for Union County until 8 a.m. Wednesday.

Major flooding is expected. Hillaker said the southern part of Iowa has been on the dry side and rivers are low. He expects the flash flooding issue to be in small streams.

“This is a once in 50 year event, getting rain at the rate of three to five inches an hour,” Hillaker said. “Hopefully it won’t be lasting long in one area.”

Temperatures are expected to reach 85 degrees Tuesday afternoon before dropping to 65 degrees overnight.

Wednesday morning will remain mostly cloudy as the storms move through the state. Highs are expected to be in the mid 70s with north winds gusting up to 25 mph.
