1203 PM EDT Monday, September 28, 2015
Gulf moisture will continue to stream into the Ohio Valley this week. A
cold front sliding down from the northern Plains will phase with an area of low
pressure ejecting from the Deep South beginning Tuesday. The result will be
fairly widespread, enhanced precipitation for much of the basin into
midweek. Unsettled weather will persist across the eastern basin the rest
of the work week as a trough deepens over the eastern US. Meanwhile,
strengthening high pressure should keep the western half of the basin dry.

The river flood potential will continue to be low.
