Forecast Discussion: Current Conditions: Cooler and drier air continues to move into the region this Tuesday afternoon with ozone and fine particulate being restricted to the good range. Temperatures are running several degrees below late July normals. For tonight, we will have a clear to partly cloudy sky with low temperatures in the upper 50s. *** Wednesday's forecast: Sunshine and a few clouds Wednesday with a seasonably warm afternoon. Some locations may even go moderate with ozone concentrations, while the dry air will maintain low levels of fine particulate. High temperatures in the middle 80s. Partly cloudy Wednesday night with lows in the middle 60s. *** Extended forecast: Clouds will increase on Thursday with showers and a thunderstorm possible late Thursday into Thursday night as a cold front comes in from the west. More clouds will limit ozone formation to the upper good range, while increasing humidity will push fine particulate concentrations to the moderate range. A wave of low pressure forming on the cold front Friday will bring more clouds and showers. Saturday will start with clouds, then the sun will return by the afternoon. High pressure will bring sunshine for the most part for Sunday. Overall air quality will be in the good range in the Friday to Sunday period, then a return to more moderate air quality is possible for the start of next week.---McAuliffe
