Discussion              

An upper-level low will push across the central states over the next few days and help to spawn an Ohio Valley surface low by the end of the week. This initial or primary low will then give way to an intensifying secondary low early this weekend somewhere near the Mid-Atlantic coastline. As a result, it looks like yet another weekend rain event for the Mid-Atlantic region that will feature a persistent onshore flow of air (NE winds) and quite cool conditions. The inclement weather is likely to spill over into Sunday with the expected very slow movement of the upper-level trough of low pressure over the eastern US.
