Current Conditions at 2 p.m. EDT this Friday afternoon: Mostly sunny skies and a clean air mass are resulting in pleasant temperatures and good air quality.

Here are the forecast details: *** Saturday’s forecast: Windy and cool with early morning cloudiness giving way to sunshine by afternoon as highs only reach the middle 60s. Strong mixing near the surface and cool air will keep ozone and fine particle (PM2.5) formation low. *** Sunday’s forecast: Winds will be less Sunday with mostly sunny skies and a nice afternoon. Ozone will go into the upper good range with the strong sun, but PM2.5 remains well down inside the good range. *** Monday’s forecast: Times of clouds and sunshine with highs in the lower to middle 70s. PM2.5 will remain in the good range, with highest values coming during the morning. *** Extended forecast: A northerly to northwesterly flow will continue through the middle of the week with good air quality.
