Forecast Discussion: PM2.5 readings are very low with the heavy rain and strong cold front moving through this morning. Ozone was good yesterday will be in the good range for a few days. A strong high pressure in Montana will build into the northern plains then into the Great Lakes by Saturday. Winds will be northerly and temperatures will be at least 10 degrees below normal then slowly improving. A weak system might trigger light showers Friday night/ Saturday morning but the rest of the period will be dry.
