Forecast Discussion: Current Conditions: As of 2 PM on Friday, partly cloudy skies prevail over the region as a weak storm system continues to make its way northward along the eastern seaboard. Right now, much of the rain associated with this system is confined to North Carolina and Virginia. Over our area, light southerly winds persist. These winds coupled with the sunshine today is helping to drive temperatures into the 70s. Air quality levels have also risen. The sunshine today has helped ozone in isolated locations reach into the low moderate range. Expect the air quality to linger in the upper good range this weekend as it remains seasonably warm and humid. *** Weekend's Forecast: Over the weekend, expect a chance of showers early on as a storm system continues to reside along the East Coast. The threat of showers will diminish by early next week as our storm system finally pushes out to sea. The cloud cover and rain early on will keep ozone confined to the good range. Levels are likely to increase as we head into the new work week as we see more sunshine and warmer temperatures move in over the region. --Nolan
