What do the inches mean?
As a rough guide: under a quarter inch in a day is light rain; 1 to 2 inches is a heavy downpour; more than 2 inches in a day is very heavy rain that can flood low-lying areas and roads.
Several rainy days in a row saturate the ground: even a modest storm can then cause flash flooding and rising rivers.

On the southern Plains it tends to bring a wetter, cooler winter; the northern Plains tend to be milder and drier.
