The snow and rain are gone and there's a beautiful week of warm weather on the way.
There are also a few warnings out.
The warm air is trapping car exhaust and smoke from campfires closer to the ground, the high ozone levels diminishing the air quality.
That's led the Minnesota Pollution Control Agency to issue an air quality alert for a good chunk of Minnesota.
The warning stretches from a far north as Bemidji all the way to the Iowa border.
The affected area includes the Twin Cities metropolitan area, St. Cloud, Hinckley, Mankato, Albert Lea, Rochester, and the tribal nations of Prairie Island, Leech Lake, and Mille Lacs.
The alert expires at 8:00 p.m. Monday, and during that time, the air quality is expected to reach unhealthy levels for sensitive groups.
They include:
*People who have asthma or other breathing conditions like chronic obstructive pulmonary disease (COPD), chronic bronchitis, and emphysema.
*Children and teenagers.
*Some healthy people who are more sensitive to ozone even though they have none of the risk factors. There may be a genetic base for this increased sensitivity.
*People of all ages who are doing extended or heavy, physical activity like playing sports or working outdoors.
Anyone who goes outside during the alert period in the affected area is asked to simply take it easy.
All this is happening while the fire danger is elevated.
Not long after a wet early spring, much of Minnesota is drying out, and windy conditions means any fire that gets out of control can spread quickly.
"It turned pretty quickly," said National Weather Service forecaster Eric Beitlich. "It doesn't take much to dry out this time of year because that sun is powerful."
The Red Flag Warning issued by the NWS runs through 9:00 p.m. Sunday.
Affected counties include Becker, Beltrami, Big Stone, Cass, Chippewa, Clay, Clearwater, Cook, Crow Wing, Douglas, Grant, Hubbard, Itasca, Kittson, Koochiching, Lac Qui Parle, Lake, Lake of the Woods, Mahnomen, Marshall, Norman, Otter Tail, Pennington, Polk, Pope, Red Lake, Roseau, St Louis County, Stevens, Swift, Todd, Traverse, Wadena, Wilkin, and Yellow Medicine.
