00:00 Several tornadoes have been reported in Iowa, including this one captured by extreme meteorologist Dr. Reed Timmer this evening.
00:07 And we've been dealing with numerous strong thunderstorms. Some have been really intense.
00:12 And Tony Laubach just 10 or 12 minutes ago showed us an up close, up front perspective on one really intense storm
00:20 that was moving through and continues to move through an area along Interstate 80 in western Illinois near Geneseo.
00:26 Well, we are tracking an ongoing severe threat here. You can see the overall risk area is kind of fractured and fragmented to the south.
00:34 But it becomes a more unified band of thunderstorms from northwestern parts of Illinois and west central Illinois all the way up into southern parts of Wisconsin.
00:41 Madison, you are now under a severe thunderstorm warning.
00:44 And I wanted to zoom in on this cell that has been bringing a bit of rotation and there's a risk of a possible tornado here
00:52 into an area that moves through Argyle here and continuing to move through parts of Wisconsin.
00:58 Now, this appears to be potentially an anti-cyclonic area of rotation, not terribly strong, but it's still some rotation.
01:06 And I say that usually in North America, about 95 plus percent of tornadoes spin counterclockwise like low pressure systems do.
01:15 But sometimes tornadoes are driven by factors that are maybe a little more localized and you can overcome the factors that drive the counterclockwise rotation.
01:24 And you can see in rare cases clockwise rotation within a storm. That's what appears to be the case here.
01:30 There's some rotation in the opposite way of what one might expect here for the northern hemisphere.
01:35 Not terribly strong, but still some risk of a possible tornado here. And the movement is to the northeast at around 25 miles per hour here.
