Wednesday Storm Threat

Outdoor plans today? You'll want to keep an eye on the radar, with the threat for storms going up late in the afternoon. Can't rule out an isolated shower or two through the early afternoon, but heavy rain and storms are in the forecast for the late afternoon.

We're watching an area of low pressure currently situated in southwest Iowa, with it's warm front in central Illinois. The low will strengthen and move east, which will lift the warm front farther north and closer to the Stateline area. This will prompt showers and storms to develop and move in from west to east. The timeline right now to expect storms would be around 4pm through about 10pm.

For the Stateline, most of the area is under a marginal risk for strong to severe storms, while our southwestern counties are included in the slight risk. Overall, we'll want to watch for storms with heavy rain at times and even some hail, as our storms remain elevated north of the front.

Closer to the warm front is where the threat is higher for strong to severe storms. South of I-80 is the area that will be closer to the approaching warm front, and area of low pressure. Therefore has a higher likelihood of stronger storms.

Rain amounts will total between .25"-.75", but localized higher amounts possible in thunderstorms. Most of the rain will be out of the area around midnight, though its possible for a passing shower into Thursday.
