That same clipper system and trailing cool front will help to develop some afternoon cumulus clouds, spotty showers and a couple thunderstorms. The best chance is in eastern Minnesota.

Intense auroras possible Friday night

The National Oceanic Atmospheric Administration’s Space Weather Center has issued their first G4 level geomagnetic storm watch since 2005. A KP index of 8.33 is forecast for Friday night with peak activity 1 a.m. to 4 a.m. Saturday. This means the auroras could be visible even into the south!

As always, it’s best to get away from city lights for the best views but no need to go north, the show could be intense statewide/region wide if everything aligns with earth’s magnetic field. Clouds from the daylight hours Friday will dissipate quickly, making for mostly clear skies for most of the state.

The sun is in an active phase of its 11 year solar cycle. Sun spot AR3664 has created several coronal mass ejections (CMEs) flying towards earth in the last few days. The sun spot is so large it’s visible from earth without any special equipment other than your left over eclipse viewing glasses (never look at the sun with the naked eye).
