The computer tornado probabilities are showing very elevated to high chances for tornadoes across northern Illinois and surrounding areas for Thursday afternoon and evening.
Looking at the latest computer models, we will have an environment extremely favorable for both prefrontal and embedded qlcs tornadoes tomorrow some likely strong and long tracked.
This is in addition to the widespread destructive wind threat associated with the likely intense MCS/squall line that develops.
Storms will be already ongoing at daybreak across western Iowa and those will be the storms to watch as they evolve throughout the morning hours. Expect pretty nasty storms across northern Illinois from west to east starting around 11am-12pm and continuing through the evening hours.
Tomorrow at this moment looks like the real deal for an ideal severe weather setup with very little failure modes. Be prepared and have shelters in place.
