Potent system for this time of year. Can only wish we had deep moisture with 70 dewpoints instead of the upper 50's at present. Strong storms southeast of Eau Claire may trend more southeastward this evening. SPC has upgraded risk to moderate because of straight line wind potential. I also note helicity values of 250/300 m2/s2 in southeast Wisconsin and NE Illinois. Tornado touchdown reported at Stevens Point.
 
Those are some pretty nice velocity couplets on a few of the storm currently in southern and central WI... Multiple tornado warnings on them for good reason. SPC mesoanalysis shows instability is weak to moderate over this area, and will likely decrease as the sun starts to set... However, the approaching 80+kt 500mb jet max now entering central MN will likely drive these storms as they become damaging wind producers with time... However, that supercell over southcentral/southwest WI looks to be entering a favorable low-level shear environment, so a continued tornado threat, I'd think, should be present with that supercell...

Tor sighted southern Waukesha county, looks like currently hook echo western Racine county. Unfortunately positioned on north side of storm, too dark to see much anyway except the occasional spectacular lightning.
 
Madison

I am out of town so this is 2nd hand.... but my co-workers (who are mostly mets) say a tornado went through parts of the Research Park area of Madison, WI around the Whitney Way/Mineral Point Road area. My office building either took a direct or indirect hit. If anyone is familar with Madison, I work in the first bank building on Rosa and Mineral Point.

The latest on this storm is 7 tornadoes hit south central Wisconsin. Several counties have just been declared disaster areas by the Governor.

In the Madison area alone the newspaper reported over 1,000 trees uprooted and over 200 homes damaged. Estimated costs to repair are over 1Million and climbing.

I live three blocks from where the tornado hit. As a new tornado spotter, I was outside looking for the storm. The sirens went off 10 minutes before it hit, so I was expecting to see something. I never saw the tornado because my view to the NW was blocked by trees, but when it came down it was extremely loud. It sounded a lot like the loud roar of a jet engine and getting louder. Thinking it was coming straight at me from an area I couldn't see, I headed in and to the basement. The tornado was on the ground for about a half mile, then went back up, and came down a half mile east for another half mile, then it went up, and came down a third time. Where it came down trees were ripped out and thrown around, houses and businesses lost parts of their roofs or siding. Power was out for a day by me, and several days at ground zero. This was an F0 to F1 they said. I always seen pictures of tornadoes, but never actually heard one. They are violent storms and they make a lot of noise, more noise then in the movies. When I think of what is causing the tornado, the amount of air being brought in to the storm, it just amazes me.

Things I noticed were a yellow turbulant sky hours before. Then a lot of low dark clouds moving fast different directions just minutes before the tornado came down. Also there was a patch of green clouds high above just north of me. Here's a picture I took just before the tornado hit, in that general area.
