KNOW YOUR FLOOD TERMINOLOGY: WHAT FLOOD WATCHES, WARNINGS AND EMERGENCIES REALLY MEAN
A lower-probability but higher-impact scenario could unfold across parts of central and eastern Missouri into south-central and southwest Illinois this afternoon if a better-defined surface low develops along the front and deepens through the day, according to the FOX Forecast Center.

If this happens, the setup could result in a localized corridor with an enhanced tornado threat due to increased low-level shear.
The development of these severe storms will majorly depend on morning cloud cover and ongoing rain.
HERE’S HOW WEATHER WILL IMPACT THE 2026 FIFA WORLD CUP
An expansive storm system is expected to track eastward across Missouri and Illinois Sunday morning, leaving a residual outflow boundary in its wake.
A cooler day with lingering morning showers would heavily suppress the instability in the atmosphere and limit the strength of afternoon storms.

If early daytime clearing happens along and south of this outflow boundary, the environment will rapidly destabilize. This would maximize the threat of all severe hazards, including tornadoes, the FOX Forecast Center said.
If this tornado threat materializes, it will notably impact Illinois, which has seen an influx of tornadoes this year.
So far, 144 tornadoes have touched down in Illinois, which is nearly double the state with the next highest count, Mississippi, which has seen 73 tornado touchdowns.

This marks a new state record for Illinois, shattering the previous record of 126 set just last year. Illinois only averages 54 tornadoes per year.
