This first band of smoke is currently impacting northern Minnesota as it moves east during the day Friday. Air quality will worsen across northeast Minnesota Friday evening as smoke arrives over the region. A second round of smoke will move into northwest Minnesota late Friday evening. This smoke will be more widespread as it moves southeast overnight, and by Saturday afternoon the entire state may be impacted. The heaviest smoke on Saturday will be across the northern half of the state. Air quality will begin to improve across western Minnesota Sunday morning as cleaner air moves in from the west. By Sunday evening, the smoke should be gone from most of the state. Another round of smoke is possible across far northern Minnesota Sunday night.
INSTRUCTION: Sensitive groups, such as people with lung disease (including asthma), heart disease, and children and older adults, should limit prolonged or heavy exertion. Reduce or eliminate activities that contribute to air pollution, such as outdoor burning, and use of residential wood burning devices. Reduce vehicle trips and vehicle idling as much as possible. Keep windows closed overnight to prevent smoke from getting indoors.

Drizzle is precipitation in the form of water droplets which are
smaller than raindrops.
Drizzle is characterized by fine, gently falling droplets and typically does not
impact human habitation in a negative way. The exception to this is freezing drizzle,
a condition where drizzle freezes immediately upon reaching earth's surface.
Freezing drizzle is still less dangerous than freezing rain, but can
potentially result in hazardous road conditions.

Next Topic: Fractus Clouds
Fog is technically a type of stratus cloud, which lies along the
ground and obscures visibility.
It is usually created when humidity in the air condenses into tiny water droplets.
Because of this, some places are more prone to foggy weather, such as regions
close to a body of water.
Fog is similar to mist; both are the appearance of water droplets suspended in
the air, but fog is the term applied to the condition when visibility is less than 1 km.
