Friday's severe weather threat across northern Illinois

Latest Severe Outlook:

The severe weather outlook saw little to no change overnight as the Storm Prediction Center maintained a level 2 of 5 Slight Risk for the area. 

 

 

 

Timing Out the Storms:

Now, today's severe threat is broken into three distinct periods: a morning threat, a possible afternoon threat, and then an overnight threat. 

Morning (6AM-10AM: This will include a batch of widespread rain and isolated non-severe storms. If any storm were to become severe, it would be for hail as these will be elevated in nature.  

Afternoon (12PM-6PM): There will be a few lingering storms behind the stuff that passes through during the morning. However, we have a warm front hovering around northern Illinois, northern Indiana, and southwestern Michigan. Any storm that interacts with this warm front will quickly go severe, posing a threat for all severe hazards. The odds of that are low but still something to monitor. 

  

Overnight (9PM-6AM):  

Thunderstorms developing along the cold front will move into the Stateline closer to the midnight hour, with chances lingering into early Saturday. These will primarily pose a damaging wind threat, but with plenty of spin in the atmosphere still in place, an isolated tornado or two cannot be ruled out. Again, be sure to have many ways to receive severe watches and warnings from start to finish today.
