The risky outbreak of severe thunderstorms - including damaging winds, large hail, and violent, "long-track" tornadoes - is directly connected to a weather system annoying millions in Colorado with a return to winter.
Some of the hailstones from the most violent storms could reach the size of baseballs.
The victim, whose name hasn't been released, had been inside a vehicle in a rural area south of Elk City, said Lonnie Risenhoover, the county's emergency management director. Oklahoma City is not in the high risk area but is likely to still see severe thunderstorms roll through by Thursday evening.
MidAmerican Energy Co. reported that 4,000 customers in western Iowa lost power, but by 10 p.m., the number of customers still without power had whittled down to about 1,500.
Much of the severe risk will depend on how unstable the atmosphere can become by way of clearing skies and warming temperatures, according to the weather service. Thunderstorm chances will continue on Friday afternoon and again through the weekend.
Two people were killed Tuesday - one in Wisconsin and another in Oklahoma - following tornadoes and severe storms that ripped through several states.
On Friday, an isolated storm will be possible, but, the bulk of the next round looks to come in late Friday night into early Saturday morning. There is a risk for scattered severe storms containing damaging wind and hail up to an inch possible with some isolated storms that could contain hail up to 2 inches in diameter. However, storms may still be strong to severe as they approach the area. The chance for rain is 90 percent through the overnight hours in Topeka.
We're becoming more concerned with an increasing very large hail and damaging wind event across parts of North Texas through late evening.
Monday's high in Madison was 85 at 3:06 p.m., 17 degrees above the normal high and 2 degrees below the record high of 87 for May 16, set in 1951, 1977 and 1992. New rainfall amounts between a tenth and quarter of an inch except higher amounts possible in thunderstorms.
Sun: High: 74 Low: 49 Mostly sunny. These are the same categories we were in on Monday, in which parts of our area were impacted by 70 miles per hour winds and tennis ball-sized hail.
