Forecast Discussion
Tuesday: The area will be on the northern edge of upper level ridging, which will push temperatures into the 70s. A trough will dig southward from the the northern Plains with an associated cold front moving through the mid Mississippi River Valley. A front to the south of the area will move northward as a warm front early in the day. All of this will keep the unsettled weather in place for the area with overcast skies and small rainfall amounts. Winds will be from the south at 5-10 mph. PM2.5 is expected to be borderline green/yellow with it ultimately being in the upper GREEN range for the day. ML

Wednesday: A cold front will approach the area over the course of the day and will move through the area near the end of the day. This will create overcast skies all day long with a good chance for rainfall. Winds will be out of the south to southwest at 10-15 mph. The strong wind flow and rainfall is expected to put PM2.5 in the GREEN range for the day. ML
