Forecast Discussion: Thurs : PM2.5 readings are good central and moderate south. High pressure will maintain cold dry weather through Friday with strong subsidence. Saturday, a warm from will move from the southern plains through the region. Some brief freezing rain may precede that front very early Saturday morning. The high retreats to the Atlantic coast and strong circulation around it will bring temperatures above normal. For Sunday dew points will be high enough for heavy rain and even a non-severe thunderstorm. Another closed low will move southeastward from Canada and merge with this system, combining into a fairly powerful system Monday in the Great Lakes. Temperatures will fall Monday and stay sharply colder into next week.
