Forecast Discussion: Current conditions: High pressure is building to our south this Wednesday afternoon, but despite the return of sunshine, temperatures are only recovering into the middle teens. In addition, mixing has not been sufficient enough to bring fine particulate levels below the moderate range. Partly to mostly cloudy overnight and not as cold with lows close to 10 degrees. *** Thursday's forecast: Breezy Thursday with sunshine most of the time, and not as cold in the afternoon as temperatures climb close to 30 degrees. Increasing westerly mixing will send fine particulate levels down to the good range. Partly cloudy Thursday night with lows around 20. *** Extended forecast: High pressure to our south will result in winds shifting into a southwesterly direction Friday and continuing into the upcoming weekend. With the southwesterly flow, temperatures will warm to above normal levels, possibly reaching close to 50 degrees by Sunday. With milder air and rising relative humidity, PM2.5 levels will average in the moderate range Friday into the weekend. The next cold front will bring rain to the area early next week.---McAuliffe
