Forecast Discussion: Current Conditions: At 2 p.m. EDT this Friday afternoon, northwest winds were blowing in response to a large area of high pressure building in from the Great Lakes. The amount of mixing is such that both ozone and fine particulate remain in the good range. Temperatures are also approaching the 70 degree mark with a fair amount of sun. There will be a shower in one or two places through this evening, otherwise dry weather will prevail through most of the upcoming holiday weekend. Mostly clear and cool for tonight with winds diminishing. Lows will dip into the middle 40s. *** Saturday's forecast: High pressure will build overhead on Saturday, and shut the wind off to a large degree. Very dry air in place will promote low levels of fine particulate. Ozone will be on the increase as the sun will be out most of the time, but will remain in the upper good range. Afternoon temperatures maxing out close to 70. Not so cool Saturday night with a mostly clear sky. Lows in the middle to upper 40s. *** Sunday's forecast: As high pressure begins to shift to the east of us on Sunday, winds will start to come out of the southwest. This will lead to warming, and it will also increase ozone as well as PM2.5. Both parameters will make the moderate range by the afternoon. Warmer with a good deal of sun as the mercury climbs into the upper 70s. *** Monday's forecast: The warm front that was advertised to be close to our region Monday now looks as though it will be a little farther to the north. This will mean ozone and PM2.5 will climb into the moderate range once more, and any afternoon or evening convection will be more limited. Afternoon temperatures will go into the lower to middle 80s. *** Extended forecast: A warm and humid weather pattern will continue into the middle of next week with a south to southwesterly flow. Factors which might limit ozone formation will be increased afternoon and evening thunderstorm activity, as well as a possible maritime influence if the winds go more southerly than forecast. As a result, ozone levels will be mainly in the upper good to lower moderate range. Higher than average humidity levels as well as limited mixing will keep fine particulate mostly in the moderate range.---McAuliffe
