Shower chances increase Tuesday afternoon... But a much wetter system is setting up Wednesday through Friday. We've issued First Alert Weather Days Thursday and Friday for the potential of heavy rain and localized flooding concerns.

Brace for a wild weather ride in central NC as a cold front brings heavy rain, gusty winds, and a 50-degree temperature drop by Friday morning.

It's as a low-pressure area rides through this unsettled weather, kicking off more of an atmospheric river event. Winds may gust above 50 mph if this low tracks through, and rain will turn heavier, and mountain snow will intensify. Snow levels will bump back up above 4,000 feet at times.

Emergency responders stayed busy Saturday night and Sunday morning as drivers tried to get through rain-soaked streets. The Baton Rouge Fire Department responded to 18 calls overnight related to weather.

According to NBC 5 Storm Team Meteorologist Alicia Roman, Friday morning's rain will be the first of two stormy waves to hit the Chicago area. The first round was expected to move mostly across northern Illinois and impact far north and west counties, along with areas in southeastern Wisconsin.

Heavy rain that hit parts of the Chicago area caused some localized flooding Friday. Some homes, streets and vehicles were damaged in the south suburbs. Video from Friday night in Lynwood shows a downpour. There was flooding in South Chicago Heights and Steger. Witnesses said some drivers needed to be rescued.
