Low pressure system over Iowa this morning, and it's warm front near the Quad Cities, will provide the threat for strong to severe storms possible near it this afternoon.
While the ingredients are all there for strong storms, it isn't set in stone. But right now, storms look to develop to our west after the lunch time hour today. However the higher threat for stronger storms will arrive closer to 3/4pm and will last into the early evening. There is a threat for all severe hazards, heavy rain, lightning, strong winds, hail, and even isolated tornadoes possible. The highest risk for this lies closer to the Quad Cities and areas south near the system's warm front with the storms still in cellular form. As they move east they will come together in a line, and will then bring a higher threat for strong winds and heavy rain.
A Flash Flood Watch will go into effect at 1pm and will last through 1am with 0.50" to 1.50" of rain possible across northern Illinois and southern Wisconsin. A slight risk from the Storm Prediction Center is in place east of the Mississippi River and extending across the Stateline and most of Illinois. It will be an afternoon and evening to stay weather aware, and make sure to have a way to receive watches and warnings if we get them.
