While not much has changed on the outlook with SPC the area the most noticeable change was the probability area for our Tornado risk. This still sits at a 2% probability. I will share the updated image from SPC in the comments of this post for those wishing to see it. Our focus is still NW indiana including Lake,Porter,Jasper and Newton counties.
Good morning, everyone. We anticipate another day of severe weather. Last night's storms primarily tracked southeast, largely bypassing Northwest Indiana, though we did experience significant lightning activity. Regrettably, several tornadoes were reported across Illinois and parts of Indiana late last night and into the early morning hours.
While we do not expect severe weather in this immediate area until later this evening, the timeline remains subject to change as new models and updates become available. Our current projection indicates a potential onset around 7 PM.
The primary threats for today continue to be damaging winds and hail, alongside flash flooding. Additionally, there is a minor 2% tornado risk that we will monitor closely throughout the day. As evidenced by last night's events, even a low probability does not preclude an occurrence. Therefore, preparedness and continuous weather awareness are paramount.
