Forecast Discussion: Ozone readings were all good except one in Louisville yesterday. PM2.5 readings are good north of the Ohio River and moderate south of the river. The surface high pressure in New York state will move into the Atlantic which the upper level ridge will build into the Carolinas then slowly westward. Tomorrow and Sunday an upper level trough with a vortmax (vorticity maximum, an area of peak uplifting) will move through increasing the chance of showers. Winds will be consistently southerly and humidity will be high through the holiday weekend so rainfall amounts may be heavy. Another vortmax will pass Monday triggering more showers. A cold front may drop through the state or perhaps stall on Tuesday.
