Iowans Could See the Northern Lights Thursday Night

The northern lights may return to Iowa skies Thursday evening, according to a forecast from the Space Weather Prediction Center (SWPC).

Aurora Borealis Overview

Also known as aurora borealis, the northern lights are natural light displays in the northern hemisphere caused by charged particles from the sun striking Earth's atmosphere. NOAA describes them as “beautiful light curtains formed when energetic particles from the sun strike the atmosphere.” A similar phenomenon occurs in the southern hemisphere, called “aurora australis.”

Forecast and Viewing Conditions in Iowa

The SWPC forecast indicates a strong chance the northern lights will be visible across the northern U.S., with the viewing line crossing near Iowa’s southern border. Residents in northern Iowa will likely have a better chance to witness the aurora on Thursday night.

However, weather conditions may limit visibility for some. The National Weather Service predicts significant cloud cover throughout much of the state around 9 p.m., especially near Des Moines, where cloud cover is expected to be about 95%. Skies should be clearest near Iowa's western border. Clouds are anticipated to clear overnight, with cloud cover near Des Moines dropping to 36% by midnight.

Additional Factors Affecting Visibility

The moon phase on Thursday night will be a waning gibbous with 98% illumination, which could reduce the ability to see the northern lights clearly.

Summary: Iowa residents may glimpse the northern lights Thursday night, especially in northern and western areas, but cloud cover and a bright moon could limit visibility.
