Forecast Discussion: Current Conditions: A small area of high pressure is bringing pleasant conditions to the region this Thursday afternoon. With dry air in place and warmth being more limited, ozone and fine particulate are in the upper good range. Tonight will be mainly moonlit, but with light winds, fine particulate will rise into the moderate range later on. *** Friday's forecast: Periods of clouds and sunshine Friday as high pressure slips a little to the east of us. A light southwest wind will bring fine particulate into the moderate range in spots, and ozone will be in the upper good to lower moderate range, depending on how fast afternoon convection develops. Highs in the lower to middle 80s. Partly cloudy and humid Friday night with lows in the middle 60s. *** Extended forecast: A strong cold front crossing the area Saturday night will put an end to our string of summerlike days by Sunday. More clouds than sunshine on Saturday with chances for thunderstorms increasing. Ozone concentrations will be limited to the upper good range as a result. Enough humidity should remain to keep PM2.5 in the moderate range. Turning much cooler Sunday into Monday with considerable cloudiness and the chance for a couple of showers. The cloud filled skies should prevent ozone from forming too much, and there will be enough of a northeast wind to bring PM2.5 down into the good range as well. ---McAuliffe
