Showers and scattered thunderstorms will affect much of the lower Missouri Valley today through Thursday, according to the National Weather Service. Widespread severe weather is not expected at this time.
The combination of a tropical airmass along with very efficient rains will lead to heavy rain and increasing threat for flooding and flash flooding both today and Thursday, the weather service said.
In addition, persistent and very efficient rains will further prime the soil for possible more widespread flooding later this week when the remnants of Hurricane Gordon move through the area, according to the weather service.
With several days of rainfall expected, and with the potential rain amounts, flooding will be a concern across the entire area through the upcoming weekend, the weather service said.
The track and location of heavier rain will depend upon several factors, which may change, according to the weather service. Forecast rainfall amounts and locations will be adjusted as forecasters approach the end of the week.
The remnants of Hurricane Gordon are expected to lift north into the lower Missouri Valley by the weekend, the weather service said.
Abundant moisture associated with this system will move into the region which could lead to widespread heavy rainfall and the threat for additional flash flooding through the late week and early weekend, according to the weather service.
