In many parts of the United States, spring is the flood season. Some of the factors at work here include all the snow that must melt at northern latitudes, high water levels on rivers and streams, higher moisture content of the ground and storms that bring quite a bit of rain. Obviously, flooding occurs in all seasons, but there seems to be a higher frequency in more places during the spring.

Flash flooding is something that will need to be reckoned with during the next three days. A series of disturbances originating over the Plains will each bring moderate to heavy rainfall. Through Thursday, the largest rainfall amounts are likely to be from eastern Oklahoma to the lower Ohio River Valley.
