Forecast Discussion: Current Conditions: As of 2 PM on Friday, mostly sunny skies prevail over the region as a ridge of high pressure, situated just off to our west, continues to control our weather. This ridge is helping to steer a storm system along the Mid-Atlantic coastline further out to sea. Right now, westerly flow is helping to keep cool and dry conditions over the area. In fact, temperatures have only risen into the upper 20s as a result. The cooler, drier air has, in turn, kept PM 2.5 levels within the good threshold today. Expect an increase in air quality levels tomorrow and for the remainder of the weekend as high pressure remains central to our driving the weather pattern over our area. Now onto the day-to-day details... *** On Saturday, mostly sunny skies will continue to persist over the region as higher pressure remains situated along the eastern US. This high pressure system is expected to keep the flow moderate as temperatures slightly climb. In fact, afternoon highs are expected to rise back into the low 40s. The combination of moderate winds out of the southwest along with the rising temperatures and dewpoint levels will force PM 2.5 levels into the low moderate range. --Nolan
