I personally do not see major river flooding but if someone gets 3-5" (or more) there would definitely be some flooding on roads and maybe small creeks.  With this spread out over 24 hours it should really change everyone out of D1 drought conditions and most out of D0.

  - Numerous showers and thunderstorms will develop through the
    day, and continue through the night. Some of these storms
    will move slowly and produce heavy downpours. Many areas will
    have multiple showers and thunderstorms today and tonight,
    leading to the possibility of flash flooding. Locations which
    received heavy rain on Sunday will be most at risk to have
    flooding occur.
