We won't sugar coat it. Tomorrow has the potential to be very bad for some in IL, but also has a potential to be minor for many.
We know, some of you will say what's the point then if we don't truly know. Well, when we see a potential for strong, potentially violent tornadoes and destructive hail, we want to convey that. We also want to convey why it could be limited too. Here's what we're seeing:
We know a morning round of thunderstorms will move in after 3AM and continue into the lunch hour. Some of these could carry wind and hail, maybe an isolated tornado. That is why central IL has start times as early as 8AM to account for this.
These storms will exit, but when they exit is critical:
1. If they exit by noon and we see some clearing, then more of central IL(the pay close attention region) will see significant severe weather including long track tornadoes and massive hail, turning into a destructive wind and embedded tornado risk as they grow upscale.
2. If these storms hang around until 2-3PM and cloud cover stays, then storms in the "pay attention region" will be lesser severe in the afternoon but still pose some risk for isolated tornadoes and strong winds.
Right now it could go either way. This is why we want you to pay attention because it's a boom or bust situation for you.
If you live in the "be prepared" region, we feel the potential is higher for you as storms will be more north of you midday and instability will really stream in. This region has the highest potential for significant severe weather including hail up to tennis ball sized, tornadoes potentially strong to violent and destructive winds. That is strong wording we know and it isn't something we post lightly. This set up really is that conductive. Be prepared in this region and look into postponing plans and traveling.
Up north in the "still be aware" region, we still think some wind risk will materialize in the afternoon as we have a very high sheared environment. A few isolated tornadoes are on the table but we think the higher tornado risk is to your south. Still be aware that there is some potential though and don't discount it.
Weather Anxiety: We know nerves are high. We know wording was strong. We know you're tired after a long season already. That is all valid. Please, stay prepares and aware. This will keep you safe. Knowing your location and surrounding counties means you can seek shelter well in advance when storms are nearing your neighboring towns. Also, keep in mind that even in the biggest tornado outbreaks a majority will still be fine. Have a plan in place, follow updates tomorrow and be aware, this will keep you okay and we'll all be enjoying the beautiful forecast coming up after this.
Is it safe to send kids to school? Yes, schools are prepared for this and they will be watching closely. We can't speak for schools but we wouldn't be surprised to see some early dismissals tomorrow if the forecast starts to trend in the stormier scenario. This is just something we're mentioning so you're not caught off guard. After school activities may also be cancelled in some parts. Just have a plan in case this does happen.
Monitor for updates and we'll be watching closely all day for you tomorrow.
