    Message Summary: ...locally heavy rainfall event shaping up across the area for sunday with flash and river flooding possible...
    A deep mid-level trough will swing through the central plains with an associated deepening surface low late this weekend into early next week. This low will move slowly into the midwest and drag a cold front toward and through the lower mississippi valley between late saturday and early monday. The combination of an intense and divergent upper level jet across the lower mississippi valley and strong influx of very moist air from the gulf of mexico should enhance torrential rain potential from thunderstorms anticipated over the forecast area, mainly sunday. Widespread 2 to 3 inch rainfall totals are expected but there is potential for a north to south oriented axis in the forecast area to experience prolonged training of storms and localized rain amounts in excess of 5 inches. Some uncertainty remains on whether this axis will materialize and especially on where this axis might set up. Of course associated flooding potential will go up markedly in areas that would be affected by this potential heaviest rain axis. As we move close to sunday the details of this event will come into better focus and our confidence will increase. As the system moves across the area from late saturday night into sunday, rainfall rates will be very high producing high amounts and flash flooding across the arklamiss region. Many small streams and rivers will be impacted with minor to moderate river flooding possible. The rivers most vulnerable to flooding will be the big black, pearl, chickasawhay, leaf, and tallahala creek. Some river flooding could be significant. Rivers and bayous across southeast arkansas and northeast louisiana will see very sharp rises with some going into flood. Those living along small streams and flood prone areas should take preparations now to remove any debris from drainage systems due to flooding that occurred in early april. As stated, there is still a lot of uncertainty in the axis of heaviest rainfall amounts. However, we do know that rain rates will be intense and could lead to some localized flash flooding. Please stay tuned to local media and your national weather service as we approach this rainfall event.
