April 3-5 Severe Weather Outbreak Series: 18z NAM/12z GFS Analysis

This is an analysis about the images issued previously in this post.

NAM ANALYSIS
The 18z NAM definitely pulled back on the way of tornado threat in North Illinois. However, that region is still outlooked as a big risk area, especially North Central Illinois.
The Weather Centre, seeing how volatile this situation may be, has issued an image for this situation.
The Weather Centre is concerned with the area outlined as an 'Elevated Tornado Threat' as a low level jet stream will provide the threat for damaging winds and tornadoes. With the Significant Tornado Parameter at levels that we view as extremely concerning, this will be a very tender and volatile situation.
More updates as they come.
