Northern lights visible in Illinois Monday night. Will the Chicago skies be clear enough to see them? — NBC Chicago

People in at least 30 states, including Illinois, were able to catch a glimpse of the northern lights Sunday night, and Monday brings another chance to see them.

According to NOAA’s Space Weather Prediction Center, a “full halo” CME — a large ejection of plasma and magnetic field from the Sun’s corona — occurred Friday, which could cause a “small” to “moderate” geomagnetic storm Sunday. and Monday.

As a result, dancing waves of light, also known as the aurora borealis, appeared across the United States on Sunday night. Those opportunities could extend into Monday night, according to NOAA officials.

According to NOAA’s tweet, “Geomagnetic storm conditions are expected to continue at Strong (G3) or higher magnitudes through April 24 at 0600 UTC.

However, the conditions and cloud cover on Monday will not be favourable As they did on Sunday.

Although Monday is expected to be partly sunny, increasing clouds are expected to move in late Monday and overnight. That means, NBC 5 Meteorologist Alicia Roman says, clouds can block your view.

“Unfortunately, we expect cloud cover to increase this evening as rain starts to move up over the area, so the outlook doesn’t look great from a weather perspective.”

However, if the clouds clear, the best viewing is between 10 p.m. and 2 a.m., away from dark areas and city lights, according to NOAA.
