Showers at times Sunday; recap of weekend rain totals

Near-normal temps this week

Most of Minnesota was either abnormally dry or in drought on the U.S. Drought Monitor report that was posted last Thursday.

We had some welcome rain in parts of Minnesota Saturday and Saturday night. Here’s the rainfall map from 7 a.m. Saturday to 7 a.m. Sunday:

Isolated thunderstorm chance Sunday

A low-pressure system to our east will move slowly away Sunday, so the best chance of thunderstorms will shift into parts of Wisconsin.

We’ll have areas of wrap-around showers in Minnesota Sunday with an isolated thunderstorm also possible. It won’t be raining all day but it will be raining at times.

The Minnesota Pollution Control Agency has issued an air quality alert for northern Minnesota that will continue until 9 a.m. Monday:

Here are details of the alert, from the MPCA:

Air quality alert expanded due to wildfire smoke for northern Minn. through Monday, June 26 at 9 a.m.

Air quality is expected to reach orange in northern Minn., which is unhealthy for sensitive groups.

The Minnesota Pollution Control Agency (MPCA) has issued an air quality alert for northern Minn. for fine particulate, effective Saturday, June 24, through Monday, June 26, at 9 a.m. The affected area in northern Minn. includes Bemidji, East Grand Forks, International Falls, Two Harbors, Hibbing, Ely, Duluth, Roseau, and the tribal nations of Red Lake, Leech Lake, Grand Portage, and Fond du Lac.

Northerly winds are bringing smoke from wildfires north of the Canadian border in Ontario into northern Minn. This batch of smoke will be heavier and more persistent closer to the Canadian border, while the southern portion of the alert area may see occasional smoke. Smoke will continue over northern Minn. through early Monday. People should keep windows shut to prevent smoke from entering. Smoke will circulate around the northern periphery of a low-pressure area heading eastward through Minn. Some smoke may linger on Monday, but concentrations should fall below orange.

Fine particle levels are expected to be in the orange AQI category, a level that is considered unhealthy for sensitive groups. In the orange area, sensitive groups should avoid prolonged time outdoors.
