Springfield, Illinois – A Level 3 enhanced severe weather risk is in effect across central Illinois today, increasing the likelihood of tornadoes, damaging winds, and large hail along the I-55 and I-70 corridors.
According to the US National Weather Service Central Illinois, the severe weather outlook has been upgraded for areas near and south of Interstate 70. Forecasters say this region has the highest probability of tornado development, some of which could become strong.
The main time frame of concern is between 11 a.m. and 9 p.m. Storms are expected to move northeast at approximately 45 mph, which could reduce warning lead time as cells track across communities including Springfield, Decatur, Effingham, Champaign, and Mattoon.
Wind gusts over 60 mph are possible with stronger storms. Hail may range from quarter size to as large as golf balls. Flash flooding is currently considered a minimal threat, but isolated heavy rainfall cannot be ruled out.
The Storm Prediction Center categorizes the tornado risk at Level 3 out of 5 near and south of I-70, with a Level 2 wind and hail risk across a broader portion of central Illinois.
Residents are urged to review severe weather safety plans, especially those who may be at work or school during peak storm hours. Fast-moving storms could impact afternoon commutes along I-55, I-57, I-70, and I-72.
Young drivers and students traveling after classes should remain weather-aware and monitor official updates throughout the day.
