Live updates: Tornado Warnings issued as dangerous severe weather outbreak slams the Midwest

Key Points:

• Despite a rare Level 4 Moderate Risk designation and high atmospheric instability, the expected widespread tornado outbreak in the Midwest has underperformed so far due to convective contamination from a morning storm complex that suppressed daytime heating and storm intensification.
• A Particularly Dangerous Situation (PDS) tornado warning was issued for a large and extremely dangerous tornado near Charleston, Illinois, moving east at 45 mph, prompting immediate sheltering in affected areas including parts of Coles and Cumberland counties.
• Severe storms have caused widespread damage and power outages affecting nearly 40,000 customers in Illinois, with damaging winds exceeding 70 mph, large hail, and tornado potential continuing eastward into Indiana, Wisconsin, and Michigan overnight.
• The primary severe weather threat is shifting from tornadoes to damaging straight-line winds and flash flooding as intense squall lines leverage a strong jet stream, with repeated heavy rainfall expected to cause localized flash floods in central Illinois and Indiana.
• The FAA has implemented ground stops and delays at major Midwest airports including Chicago O'Hare, Midway, and Minneapolis-St. Paul due to severe weather, causing significant travel disruptions across the region.
