Smoke from Canadian wildfires has once again triggered an air quality alert across parts of Minnesota. Our forecast calls for heavy rainfall, potentially washing some of the smoke out of the air.

Air quality update

Canadian wildfire smoke has moved farther south, leading to improved air quality in north-central Minnesota. As a result, the air quality alert for that region has been canceled.

An air quality alert remains in effect for central and southern Minnesota until 11 p.m. Thursday. During this time, air quality levels are expected to reach the orange category, which is considered unhealthy for sensitive groups.

Soaking showers

A stalled frontal boundary over southern Minnesota will bring heavier rains and storms Thursday night and into Friday. Some of the models are all over the place with the exact placement of the heaviest rain bands.

On the map below, the National Oceanic and Atmospheric Administration’s High-Resolution Rapid Refresh model shows a narrow band of heavy rain for central Minnesota. In the yellow-colored area, amounts greater than 4 to 5 inches may fall.
