Forecast Discussion: Current Conditions: At 2 p.m. EDT this Tuesday afternoon, very warm and humid conditions continue across the region. With the sunshine and heat, ozone readings are moving into the code ORANGE range in a few locations. Light winds and high humidity are keeping fine particulate well into the moderate range. We will have another day of hot, humid conditions Wednesday with code ORANGE ozone levels again likely, then concentrations will lower with a passage of a cold front early Thursday. Mostly moonlit and muggy tonight with lows only dropping to 70 degrees. *** Wednesday's forecast: Heat and humidity will continue Wednesday with very light south to southeast winds. The sun will remain strong enough, when coupled with local emissions, will cause ozone concentrations to rise to the code ORANGE range. Afternoon temperatures peaking around 90 degrees. Partly cloudy and humid Wednesday night with a shower possible later on. *** Extended forecast: A cold front will move through the area during the midday hours on Thursday, and bring showers and a thunderstorm with it. This will result in a lowering of ozone levels to the lower moderate or even the upper good range. Highs will only reach into the middle 80s. A new area of high pressure building in for Friday will bring plenty of sunshine, but with ozone and fine particulate values in the upper good range. Over the weekend, a cool front may bring a scattering of showers for Saturday, but then dry weather will move back in for Sunday into Monday of next week. Ozone and fine particulate levels will average in the upper good to lower moderate range with temperatures averaging in the lower to middle 80s, close to normal for the start of August.---McAuliffe
