The cloud deck in Illinois is not breaking up to allow sunshine. Also, some showers continue with the deck. So, I cut any isolated severe risk to cover only our eastern half for a while longer (while the sun is out there & it is unstable).
The back edge of this isolated or MARGINAL RISK will gradually push eastward over the next 1-2 hours as the cloud deck & some showers from Illinois move eastward. This blotting of the sun with some cooling showers should stabilized things somewhat. There will still be some instability (storm energy/buoyancy & marginal shear/wind fields aloft), so I kept mention of an isolated storm or two mixed in the showers. However, any isolated severe risk will depart.
