A series of Low Pressures will ride along a nearly stationary boundary Tuesday and Wednesday through the Ohio Valley and up into Central Pennsylvania.

Generally light to moderate rain will follow for Wednesday morning, but some thunder is possible, especially in the southern half of the region later on Wednesday Evening and Wednesday Night, with Severe Thunderstorms possible in the extreme South. Some of the rain may be heavy enough to create some local flooding. A Flood Watch has been posted for a portion of the area. See the front page map for details.
