For the third day in a row, a severe thunderstorms will be focused along a strong warm front slowly lifting north through the Midwest.
On Sunday and Monday, the front was centered over southern and central Illinois. Today, that front will be parked over northern Illinois, which brings the severe thunderstorm threat closer to home here in Chicago.
Several rounds of storms are expected across northern Illinois, southern Wisconsin and northern Indiana today.All of the storms will produce locally heavy downpours as well as lightning. A few of the stronger cells may produce damaging winds (58mph or higher) and large hail (1″ in diameter or larger). In addition, an increase in low level moisture coupled with low level wind shear could support a tornado or two this afternoon and evening.
Locally, heavy rain is likely. If rainfall totals exceed 2 inches in a short period of time, flooding concerns will be on the increase.
