Forecast Discussion: Temperatures rise into the upper 80s to low 90s at the start of the week with a high pressure system influencing the region. Light southeasterly to southerly onshore winds on Tuesday will keep ozone in the mid to upper Moderate range. Ozone could approach the Unhealthy for Sensitive Groups range for isolated locations on Wednesday as winds turn southwesterly and skies remain mostly sunny until early evening. On Thursday, air quality will improve back to the Good range in response to the frontal passage with scattered rain showers and cloudy skies. - MDE
