Moisture will stream northeast along a slow moving cold front that will stall over the region today (Monday). A lengthy period of rain will affect southern Indiana and areas along the Ohio River from the pre-dawn hours through at least mid-afternoon. As this boundary sags south towards Tennessee, rain will become widespread over the Bluegrass and Lake Cumberland Regions later this morning . The heaviest rain totals are expected over southwestern Indiana and areas along the Ohio River southwest of Louisville. The image below shows our forecast storm total rainfall from late Sunday through Tuesday.
Currently, the ground is nearly saturated from widespread 2 to 4 inch rains that fell earlier this week. Rivers are also running high. This round of heavy rainfall likely will result in a repeat of minor flooding on area rivers, especially on the Muscatatuck and the Blue Rivers in southern Indiana. The Green and Rough River basins in central Kentucky will also see rapid rises.
