(1:30PM Friday - 4/15/22) A brief recap regarding the Thur, April 14th high wind event that impacted portions of the region and state.
Overview... The same storm system that brought a severe t'storm risk to the state and region the previous day on Wednesday (April 13th), also brought a high wind event to Northern and Central Illinois, Thursday morning through Thursday evening. This storm system tracked from the Northern Plains/Canada border to the Northern Great Lakes/Canada border on Thursday.
Summary...
Thursday Morning - Thursday Evening, April 14th ~ High Wind Event: As the storm system moved through the region on Thursday, a potent jet streak rounded the base of the associated trough through the region. This will brought a period of high winds to Northern and Central Illinois and portions of the region, Thursday morning through Thursday evening. High winds aloft, characterized by 700MB winds of 45-75KT and a low level jet (850MB) of upwards to 40-55KT, translated across the region. The combination of deep mixing up to around 800MB, along with steep lapse rates and ample sun, aided in transporting higher winds to the surface. During this period, westerly/southwesterly wind gusts of upwards of 35-50MPH to 45-60MPH occurred across Northern and central Illinois, Thursday morning through Thursday evening. Isolated power outages and isolated tree damage also occurred across portions of Northern and central Illinois due to the high winds.
