A new active weather system is predicted to bring widespread rain to the Ohio Valley beginning late Monday night and lasting through Saturday, according to the National Weather Service Ohio River Forecast Center (OHRFC).
According to the NWS, the majority of the region will receive 0.50 to 3.00 inches of rain, with the highest totals expected in the Illinois-Indiana-Kentucky border, including southern Illinois, southern Indiana, and western and central Kentucky. Rainfall over the next 48 hours will be light—generally 0.50 inches or less—as lake-effect showers continue around eastern Lake Erie Sunday into Sunday night. The midweek storm pattern brings heavier rains.
Forecast maps issued Sunday morning indicate a wide swath of moderate to heavy precipitation across the Ohio Valley, with deeper blues and purples on the 7-day outlook indicating the possibility of 2 to 3 inches in parts of the tri-state border region. Areas farther north and east, such as Ohio, West Virginia, and western Pennsylvania, are forecast to receive less precipitation but still have widespread coverage.
From Tuesday to Saturday, the following pattern will feature many waves of moisture, resulting in recurrent bouts of rain. Forecasters caution that this may lead to ponding on roads, reduced car visibility, and rising water in low-lying areas, but they do not anticipate serious flooding.
The OHRFC encourages citizens to keep an eye on revised rainfall estimates as the system evolves, particularly in southern Illinois, southern Indiana, and northern Kentucky, where the most precipitation is expected.
