CENTRAL IL – After a brief break from active weather, more strong-to-severe storms are possible Saturday afternoon and evening. Showers and thunderstorms will develop ahead of an approaching cold front during the afternoon and early evening. Lift from the cold front and plenty of moisture will allow a few big thunderstorms to pop up on the map starting as early as 3 pm Saturday. Not everyone will see severe weather, however, the greatest chance exists east of the Illinois River as scattered storms dropping through from the northwest gain momentum and strength.
The Storm Prediction Center highlights a level 3 out of 5 (enhanced) risk for severe weather east of the IL River, with areas west in a slight risk of severe storms. The main threats are damaging wind gusts between 60-70 mph and large hail. Conditions are not favorable for tornadoes, however, a brief spin-up can’t be ruled out south of I-74. The flooding threat is low but a quick downpour from a strong storm can put down an inch of rain quickly, causing minor street or parking lot flooding. The time frame for severe storms is between 3 pm and 9 pm.
Be sure to have multiple ways to receive warnings and weather information. A NOAA weather radio is the best option to get your warnings.
