A multi-day outbreak of severe thunderstorms will begin today and last through the weekend in the Midwest, South and East. Strong, long-tracked tornadoes, widespread damaging winds, large hail and flash flooding are all threats this dangerous bout of severe weather could produce.

A windy and warmer day kicks off Friday in Chicago, but a severe storm threat is expected to develop after dark, bringing with it the possibility for damaging winds. CBS Chicago meteorologist Laura Bannon says the risk of severe thunderstorms increases late Friday night.

Sunny, windy, and warm. Fire weather and blowing dust are a concern today. Strong winds, dry conditions, and low humidity means fires could easily get out of control and dust will be able to travel more easily.

The National Weather Service continues to update its forecast for Friday night's severe weather in the Tri-State. The risk of tornadoes has increased.
