Iowans brace for more after days of storms bring 'remarkable' destruction, record rainfall

A jet-stream pattern stuck over the Midwest has pummeled Iowa with tornadoes, severe thunderstorms, hail and heavy rainfall in recent days. More of the same is expected this week, forecasters say, increasing chances for flash floods in parts of the state.

Rising temperatures in the state are partly to blame, the state climatologist says.

"We are seeing warming, and with that, we are seeing more and more precipitation," said Justin Glisan, who tracks Iowa's climate for the Department of Agriculture and Land Stewardship. High-pressure systems on the country's coasts are keeping the storm system locked in place, for now, he said.
