Thunderstorms producing damaging winds, heavy rain and large hail could develop in parts of the Chicago area Monday afternoon and evening after a mild, rainy start to the week.
Severe thunderstorm warnings were issued early in the evening for La Porte and Porter counties in Indiana. Porter's was canceled by 5:45 p.m. La Porte's was expected to expire around 6:15 p.m.
Much of the area saw mostly cloudy, mild and humid morning conditions with periods of scattered showers and storms.
More showers and storms are expected to develop in the afternoon, mainly along and south of I-80. Some of the storms could be strong to severe, and while an isolated tornado is possible, the threat is low.
The storms likely will fade and then end by late evening in northwest Indiana.
High temperatures will reach the 80s, feeling hotter because of the high humidity. Lows dip Monday night between 65 degrees well inland and 73 degrees in Chicago.
The threat of scattered showers and storms returns late Tuesday morning, with a few storms possibly strong to severe in the afternoon and evening, especially in southern sections and northwest Indiana.
Wednesday looks partly sunny and seasonably warm, though still somewhat humid with highs in the low- to mid-80s inland but cooler along the lakefront.
A few showers and storms are possible Thursday night and early Friday as highs persist in the low 80s.
