Discussion: Today, moderate easterly winds due to surface low pressure passing south of Minnesota will disperse some pollutants. However, moisture associated with snow showers will enhance particle production. As a result, AQI levels will be Moderate. Tomorrow, winds will become moderate northerly as the low-pressure system moves to the lower Great Lakes region. These winds will disperse pollutants and bring clean air into the area, limiting particle production and lowering AQI levels to Good. Wednesday, surface high pressure building into the northern Plains will produce moderate northwesterly winds in Minneapolis-St. Paul, effectively dispersing pollutants and keeping AQI levels Good. Thursday, southeasterly winds in the Twin Cities due to surface high pressure over Illinois will transport pollutants into the region, resulting in Moderate AQI levels. Friday, surface high pressure over Minnesota will result in light winds in Minneapolis-St. Paul, limiting the dispersion of pollutants and keeping AQI levels Moderate. Saturday, moderate southwesterly winds will develop in the Twin Cities due to surface high pressure over the Ohio River Valley. These winds will disperse pollutants and lower AQI levels to Good.
