Forecast Discussion: Current Conditions: At 2 p.m. EDT this Tuesday afternoon, a thunderstorm or two was moving through eastern parts of the region. This convection has acted to surpress ozone formation this afternoon, but some locales in the west will move into the lower moderate range later on. Light winds have meant that fine particulate has remained in the moderate range in most locations. Temperatures are getting just above average, with readings in the middle and upper 80s. Our weather will again turn unsettled as we move into the middle of the week as an approaching cold front in the Great Lakes is expected to move southeastward and stall near us over the next 24 hours. So, for tonight we expect a partly to mostly cloudy sky and low temperatures in the upper 60s. *** Wednesday's forecast: For the day Wednesday, a frontal boundary will stall out not too far to the south of us, and this will mean more frequent rainy periods and even a thunderstorm. High low level moisture coupled with dust and smoke already present will keep fine particulate in the moderate range once more. Considerable amounts of cloudiness will prevent much in the way of ozone formation. Cooler on Wednesday with highs only reaching into the upper 70s. *** Extended forecast: A lingering frontal boundary in the northern Mid-Atlantic region will mean a continuation of mostly cloudy skies on Thursday with a couple of showers lingering as well. Low concentrations of ozone will continue, but fine particulate may stay in the lower moderate range. High pressure eventually wins out and brings a two day stretch of dry weather for Friday and Saturday. There is not expected to be much of a cleanout of PM later on in the week, so we may continue to have PM2.5 in the lower moderate range. Ozone will start off the period in the good range, but even this might go moderate by later on in the weekend with very light winds, a good deal of sunshine, and temperatures in the middle to upper 80s. Another area of unsettled conditions may move in again early next week.---McAuliffe
