Northern Lights Could Be Visible Over IL Tonight: NOAA

The northern lights could be visible over northern Illinois Tuesday night, though viewing conditions may be limited, according to federal forecasters.

Forecast maps from the NOAA Space Weather Prediction Center show northern Illinois near the southern edge of the aurora visibility zone. Those farther north of the line are expected to have a better chance of seeing the lights.

NOAA forecasts indicate a minor (G1) geomagnetic storm is possible Tuesday due to lingering solar wind effects, which can sometimes push aurora visibility farther south.

Activity is expected to weaken quickly, with lower chances for visibility on Wednesday and Thursday.

Any potential viewing in Illinois would likely be low on the northern horizon and dependent on clear skies and minimal light pollution.

Cloud cover could also impact visibility in parts of the state Tuesday night.

The aurora has been visible in Illinois in the past, occasionally lighting up the sky in shades of green, pink and purple during stronger geomagnetic events.
