Forecast Discussion: As a weak cold front moves through the state on Thursday, dew points will rise and make for an oppressively hot and humid day. A line of pre-frontal clouds and thunderstorms will move through the state, limiting ozone to the Good range. Particle concentrations will remain in the Moderate range as dew points climb into the 70s° F. Friday will be see Good air quality as a cleaner, drier air mass moves into the region behind the front. Saturday will be another day of continuing heat and light westerly winds, bringing ozone into the Moderate range. Particles are expected to continue in the Good range. - MDE/PSAQFO
