6:30pm Update: The severe threat has pretty much ended for the region Wednesday evening as the strongest storms have now moved into Indiana. There are some showers and isolated storms near Peoria that have formed just north of the surface low, but over the last 30 minutes they have weakened quite a bit.
We will see some showers fill back in from the southwest between 7pm and 8pm before a transition over to snow occurs from west to east.
Scattered showers and thunderstorms continue to move across northern Illinois, now entering into southern Wisconsin late this afternoon. While there were a couple isolated severe thunderstorms with what came through this morning, the severe threat for the afternoon has remained further south in central Illinois.
The warm front that brought our temperatures into the 60s Tuesday drifted south overnight, settling near I-80 throughout most of Wednesday afternoon. This resulted in a much more stable environment across northern Illinois. It also caused our temperatures to remain in the 30s and 40s, quite a bit colder than the original forecast. South of the warm front, however, temperatures warmed into the 60s and 70s. And this is where most of the active weather has been where there are current severe thunderstorm and tornado warnings.
The biggest threats with any storms locally will be hail. There have been quite a few reports of pea sized hail with the storms as they've moved through. The leading edge of the storms are now stretching from Rockford down through southern DeKalb County. This line will pass through the region by 6pm-7pm.
