Showers and a few t-showers are diminishing just before 4 PM. A gap (as expected) of quiet time between early storms and a new storm complex is underway.

THE SET UP - NEW STORMS DEVELOP LATER

Storms will erupt later tonight - closer to sunset especially off tho the northwest in parts of northern Illinois and Iowa. Starting as only a few small blips on the radar, these individual cells could quickly become severe and produce tornadoes.

Stay weather aware!

We are out-looked as a "MODERATE RISK" for severe storms by the Storm Prediction Center. An assessment given when severe storms are likely and the ingredients favor large scale severe storms that will be rather wide-spread later tonight.

Current thinking is that initial storms that fire up with a threat of producing tornadoes will then evolve into a large storm complex that delivers a wide swath of damaging wind. The 'wall' of wind is projected through parts of Indiana and Ohio later tonight.
