Action Day?: No
Temperature: Low 80s
Short-Term Discussion: Mostly cloudy Thursday morning with temperatures falling into the lower 60s. Skies will gradually begin to clear a bit during the afternoon. Humidity levels should increase as the day progresses and afternoon temperatures could rise into the low 80s if clouds break earlier than expected and rain showers don’t develop later in the afternoon. Thursday’s fine-particulate concentrations should reach the code YELLOW (moderate) range while ozone levels will remain in the code GREEN (good) range.
Extended: Warm air currently situated over the Midwest will work its way over the eastern seaboard. A frontal system will eventually cross the region later this weekend. The models are giving slightly different indications when this will happen but the front should cross the region by late Sunday or early Monday. Air-quality levels will most likely remain in the moderate range over the next several days.
