Showers and isolated thunderstorms are expected to continue through Wednesday before moving out Thursday.
Rainfall amounts of 50 to 75 mm are expected by early Thursday morning with a few localities possibly reaching up to 100 mm.
This widespread rainfall event is due to a cold front and a moisture laden low pressure system that will arrive from the American Mid-west.
