Satellite and surface weather observations show an area of smoke moving into northwestern Minnesota.

Periods of smoke are expected to persist in this area overnight into Thursday morning. During this time, fine particle pollution is expected to remain at or above a level that is considered unhealthy for sensitive groups.
Smoke is expected to decrease across the alert area late Thursday morning.
