Powerful low pressure generates strong winds/severe storms

|

Due to a very intense low pressure center in northern Minnesota, the National Weather Service Storm Prediction Center has forecast a moderate risk for severe storms today and tonight over much of the western Great Lakes and Midwest. High Wind Advisories have been posted for that same area today. Chicago’s greatest risk for severe storms will be between 6 p.m. and midnight. The cold front associated with this strong low center will move east of Chicago Friday morning followed by much cooler, less humid high pressure. At press time Wednesday evening, a total of four tornadoes had been reported in South Dakota, and Wyoming. A good portion of Wednesday evening’s severe weather centered over South Dakota with several large hail reports and a severe t-storm in White River that sustained 70 m.p.h. winds for 20 minutes. Earlier Wednesday, 92 m.p.h. wind gusts were recorded in Eagle, Colo.
