Forecast Discussion: Current conditions: At 2 p.m. EDT this Thursday afternoon, rainy periods continue across the area with a strong easterly flow prevailing. The strong east winds and rain are keeping PM2.5 values low this afternoon. The culprit for all of the unsettled weather is an area of low pressure to our south, and this low will move only slowly northward over the next few days, keeping plenty of clouds and the chances for rain high into the weekend. Tonight will bring an overcast sky with periods of rain and drizzle. Lows in the upper 50s with good air quality continuing. *** Friday's forecast: Rather cloudy, breezy, and cool for the day Friday with occasional rain and drizzle continuing. With an east to northeast wind, fine particulate concentrations will continue to be on the low side. Afternoon temperatures will not rise much past the 60 degree mark. *** Extended forecast: Clouds will continue to be the rule over the weekend as low pressure will be slow to leave the area. Mostly cloudy on Saturday with a few more showers. Sunday may bring some improvement with perhaps some afternoon sunshine. High pressure will then slowly start to build in by early next week, but we will keep an eye on the progress of a tropical system off the South Carolina coast. Air quality will remain good for the extended period.---McAuliffe
