How smoke reaches Saint Paul
Saint Paul shares the Twin Cities' front-row seat for Canadian smoke, which typically drops in on northwest flow from Manitoba and Ontario fires. Fresh plumes mean conditions can go from clear to Unhealthy in hours, and the river valley can hold haze after the wind turns. That is why SmokeDar reports two numbers for Saint Paul: smoke aloft (modeled aerosol optical depth from Copernicus CAMS) and surface air (PM2.5 and US AQI, observed AirNow monitor data when a monitor is nearby). They are different things, and they often disagree.

AQI 0–50 is good and 51–100 is moderate; ordinary days. From 101–150, sensitive groups (kids, older adults, pregnant people, anyone with heart or lung conditions) should shorten hard outdoor exercise. Above 150, everyone should cut both time and intensity outdoors. The full playbook is in the Smoke Guide.
