A storm system that's dropping snow on the western half of the state will bring up to four inches of rain to the St. Louis area by Sunday.
But don't expect much in the way of flash flooding, says National Weather Service hydrologist Mark Fuchs.
"We're not necessarily expecting flash flooding in the classic sense - where you see a very quick rising water coming down the stream,"Fuchs said. "But with that being said, there will be some roads in poor drainage areas that could go underwater."
