Forecast Discussion: Current Conditions: At 2 p.m. EDT this Thursday afternoon, high pressure just to the west of the area was promoting a clean and dry northerly flow across the region. The result has been low levels of fine particulate and ozone. Over the next few days as the high moves overhead or just east of us, the air will grow more stagnant, allowing for buildups of pollutants. For tonight, we expect a mostly moonlit sky with low temperatures near 60. *** Friday's forecast: Sunshine most of the time Friday with a warmer afternoon. Lighter winds and the abundant sun will cause ozone and fine particulate to increase, but most areas will remain in the upper good range in the afternoon. High temperatures in the lower 80s. Mostly clear and not so cool Friday night with lows in the lower 60s. *** Extended forecast: Warmer and more humid air moving in over the weekend with winds shifting into more of a southwesterly direction. With a good deal of sunshine and highs in the middle 80s on Saturday, both ozone and fine particulate will rise into the moderate range. Warmth and humidity will last into the early part of next week with only slight chances for afternoon or evening thunderstorm activity. Overall air quality will average in the moderate range as the mercury heads towards the 90 degree mark.---McAuliffe
