More Flash Flooding Concerns for the greater St. Louis region

(St. Louis Region; Jefferson County) The greater St. Louis region is once again under the threat for more heavy rainfall throughout Monday evening and early Tuesday morning as a cold front works its way through.

Patrick Walsh is a Meteorologist with the National Weather Service in St. Louis. He says with the recent rainfall in mind, additional heavy downpours can quickly initiate more flash flooding.

Rain will taper off early on Tuesday morning with the passing of the cold front, leaving cooler daytime temperatures in its wake.

A Flood Watch is in effect for Jefferson County and the greater St. Louis region until 4am on Tuesday.
