Severe weather alert: Tornado and wind risks in central Illinois
Key Takeaways
Severe storms are possible between 1 pm and 6 pm
All severe hazards possible
65 MPH wind gusts
Half dollar size hail
A few tornadoes, potentially strong
Gusty gradient winds up to 45 mph expected through Wednesday night
Rain changing to snow Wednesday night
There's been a big upgrade from the Storm Prediction Center which now places most of Central Illinois within a Level 3 Risk (Enhanced Risk) for severe storms.
A lot has changed since Tuesday morning as model guidance continues to trend towards a rapidly destabilizing environment Wednesday afternoon. With ample shear this should lead to the development of scattered low-topped supercells capable of producing tornadoes, some of which could be strong if the worst-case scenario comes through. The greatest tornado risk is near and north of I-74.
In addition to tornadoes these storms will be capable of producing damaging wind gusts up to 65 mph and half dollar size hail. These storms will be more hit-or-miss compared to the storms that came through on Friday night, so not everyone will see severe storms, but this has the potential to be a localized tornado outbreak for our area.
A few rain showers will be possible in the morning with the window for strong to severe thunderstorms opening in the afternoon. A broken band of thunderstorms will develop along the cold front and move to the northeast at 30 mph. The current timing of the system has storms passing through the area between 1 pm and 6 pm.
Temperatures will drop quickly behind the front with additional showers pushing in from the west. Rain will redevelop in the evening but will change to snow after midnight as temperatures fall into the low to mid 30s. Snow accumulations will be similar to what we saw Sunday morning with amounts ranging from a trace to 3.0″, highest west of the Illinois River, and mainly confined to grassy and elevated surfaces. Peoria could see up to 2.0″ of snow.

Heavy Rains and Flash Floods Threaten Midwest and Ohio Valley
Severe, slow-moving storms are expected to sweep across Illinois and Indiana on Sunday, with some areas potentially getting up to 11 inches of rainfall, significantly raising the risk of flash flooding, forecasters said. The threat stems from a cold front moving into the region, particularly in the afternoon, and stalling there, creating conditions for repeated rounds of storms that could unload torrential rains. The Weather Prediction Center has issued a Level 3 out of 4 risk for excessive rainfall across central Illinois. The center said rainfall rates could reach three to four inches per hour, and up to eight inches in some areas. Frank Pereira, a meteorologist at the Weather Prediction Center, said that a significant amount of atmospheric moisture was contributing to the risk of intense rainfall. 'Typically during the summer, we get warm humid air masses,' he said. 'But this is on the higher end of that.' A Level 2 out of 4 risk for flash flooding extended from eastern Iowa and northern Missouri to western West Virginia and as far south as northeast Georgia and western North Carolina. Much of this region was under multiple flood watches on Sunday. Damaging winds, hail, tornadoes and other types of severe weather were also a concern. The Storm Prediction Center placed central Illinois, Central Indiana, southern Ohio, northern Kentucky and southeastern West Virginia under a Level 2 out of 5 risk for severe storms on Sunday. The main threats included strong, potentially damaging winds and isolated hail. There was a low risk for tornadoes. The risk of flash flooding was expected to persist into the week. 'Indiana, Kentucky, Tennessee, there's a concern the storms in those areas may be impacted by more additional heavy rains going into Monday,' Mr. Pereira said. 'So if you get back-to-back or repeated storms, that could really elevate flooding concerns.' The Weather Prediction Center has issued a Level 2 out of 4 risk on Monday for excessive rainfall across those states, as well as for southwestern West Virginia and the far west of Virginia. The ground will already be saturated from Sunday's storms, forecasters said, and additional rainfall could reach up to three inches an hour, and locally as much as five inches, causing conditions ripe for flash flooding.
