Peoria, Ill. — A line of severe storms is expected to blow through Central Illinois Tuesday morning bringing damaging winds and heavy rain along with a chance for isolated tornadoes and hail. The Storm Prediction Center has placed Central Illinois within an enhanced risk for severe weather.
Storm Timing and Impacts
- When: Mainly between 8 am and Noon
- Primary Threats: Damaging wind gusts up to 70 mph & heavy downpours.
While an upper-level ridge brings hot an humid conditions to the Central Plains, a small disturbance riding the northern edge of this ridge is expected to bring a severe line of storms through Central Illinois Tuesday morning. These storms will develop Monday night across NW Iowa before the upper-level flow guides these storms into the region.
The storms are expected to come in the form of a bow echo with damaging wind gusts. The line of storms should arrive in Henry and Knox Counties around 9 am before dropping through the region and moving east of I-55 by noon. Damaging wind gusts up to70 mph and heavy rain are the primary threats, but isolated tornadoes and hail are also possible. There is a slight chance that the line of storms drops south sooner than expected. If this happens, the main area for severe weather will be across Missouri and western Illinois.
Once the storms move through, skies will become partly cloudy and temperatures will climb into the mid to upper 80s. While unlikely, if the atmosphere can recover after the morning storms, additional strong to severe storms will be possible in the evening.
These storms are expected to move through Central Illinois while most people will be at work or at school and away from home. Make sure you multiple ways to receive life-saving warning information including a NOAA weather radio and the ciproud2go mobile app. Also, make sure you are aware of where you can seek shelter if severe weather approaches your location.
