Forecast Discussion: The area will stuck between high pressure to the east and low pressure to the west on Wednesday. The day will start off dry, but dew points will increase throughout the day. How quickly they increase will determine how much ozone is produced. Wednesday will be hot and humid, especially in Southern Indiana. The Louisville area could see 8-hour ozone values that approach the standard. The low pressure system will effect the area by Thursday, bringing an all day chance of rain to the entire region. Heat and humidity will continue. After the cold front moves through, Friday will be cooler and much drier. Winds winds will be out the north/northeast, with skies clearing throughout the day.
