...Potential for Heavy Rain Saturday through Sunday night...

A dynamic low pressure system will then bring a surge of moisture
to the region Saturday. High moisture levels, numerous
thunderstorms, and a prolonged period of rainfall will likely
result in rises in local rivers. Rainfall totals through Sunday
night are forecast to be 2 to 4 inches, and locally higher
amounts are expected with thunderstorms.

High rainfall rates along with copious amounts of rain will likely
result in increased runoff into local rivers and streams. As such,
there will be potential for flooding, especially in low-lying
flood prone areas. Residents living in these areas and locations
along rivers and streams should pay close attention to later
forecast information. Since the bulk of the rainfall may be at
night, motorists should be especially cautious as flooding is
harder to recognize at night.
