Forecast Discussion: Current Conditions: At 2 p.m. EDT this Wednesday afternoon, the weather is rather pleasant across the area with sunshine and only a few clouds. The dryness of the air has maintained low levels of ozone and fine particulate. After a pleasant evening, tonight will turn out clear to partly cloudy. Lows in the middle 60s. *** Thursday's forecast: Clouds will be on the increase with a little higher humidity Thursday, with a shower or thunderstorm later in the day. High temperatures in the lower 80s, and with a light southwest wind, fine particulate and ozone will rise into the moderate range. *** Extended forecast: The weather remains unsettled Friday into Friday night as a cold front stalls just to the southeast and a wave of low pressure rides along it. Periods of heavier rain and a thunderstorm are likely with this scenario. Both fine particulate and ozone may drop to the good range with all the clouds and rain Friday. Saturday will bring clouds and showers in the morning, then a northerly flow of cool, drier air will commence late in the day, with some clearing. Nice weather will continue Sunday into early next week with high pressure building back into the area. Overall air quality will be in the good range.---McAuliffe
