Early Friday Afternoon - Early Saturday Morning, Feb 18-19th...
As a storm system tracked from the Southern Canada Prairies Thursday night, through the Northern Midwest and Northern Great Lakes on Friday, and then into the Northeast Saturday morning...It was accompanied by a strong jet streak aloft as well. High winds aloft characterized by a low level jet (850mb) of 45-65KT and 925mb winds of 35-55KT, translated through the region with the storm system. Adequate mixing occurred, at least up to 925mb, which transported higher winds to the surface. Additionally, as the cold front associated with the storm system moved through it was accompanied by a significant snow squall, which produced isolated higher wind gusts. During this period, wind gusts of 35-55MPH occurred across Northern and portions of Central Illinois.
