Excessive Rainfall Risk Outline for Wednesday through Friday

A Look Ahead
As another area of low pressure develops on Saturday, heavy to excessive rainfall will continue for portions of the Ozarks into the Ohio Valley. This will allow for a continued threat for flooding and flash flooding. Across the Central Plains and Midwest, snow is expected to develop. This snow may be heavy at times with snow accumulations ranging 3-6 inches and locally higher amounts in excess of 8 inches.
