Forecast Discussion: Tuesday, November 19, 2019:A slow-moving warm front extending from northern Minnesota through the Twin Cities southward into Iowa is moving very slowly eastward. Fog, drizzle, and low clouds with light winds has been the the result over the eastern half of the state today. Fine particle pollutants increased along and ahead of the front due to the light mixing and high moisture in the lower atmosphere. Yellow (moderate) air quality will continue from the Arrowhead through the Twin Cities into parts of southeast Minnesota this afternoon and evening. On Wednesday, an approaching storm system will increase clouds and introduce light rain south (evening into overnight) and snow north (late morning/early afternoon). AQI values to climb slightly back into the Yellow category for areas of southern Minnesota including the Twin Cities and Rochester as fine particles transport into the area within southeasterly winds. Green (good) air quality for the rest of the state. Thursday will start with moderate snow falling over the northern 1/3 to 1/2 of the state with best accumulations over the BWCA and Northshore region. Lighter amounts toward the central/east central areas, staying mainly north of the Twin Cities metro. Air quality will improve quickly as brisk north-northwest winds sweep across the state with snow showers rapidly diminishing. Quiet weather on Friday with west-northwest winds and Green AQI values expected statewide.
