Why is it so hot in Iowa?

From abnormal coldness to summer-like heat, we're asking: What the heck happened to spring in Iowa?

• Well, you can thank warm temperatures from the southwest for our 90+ degree forecast, Roger Vachalek, a meteorologist at the National Weather Service in Des Moines, told Axios.

State of play: A low-pressure system to the northwest of us has been pulling in warm and humid air from the south on and off this last week.

• It's expected to move out of the state by the end of the weekend, bringing back the more tepid May we enjoy.

The intrigue: Have the clouds looked a little hazy to you?

• Not only are we pulling in heat, but also smoke from the wildfires in New Mexico, according to the NWS.
