ILLINOIS — Illinois schools could face closures or schedule disruptions next week as forecasters warn of the potential for a significant severe weather outbreak across parts of the Midwest beginning Sunday and continuing into early next week.
The National Weather Service’s Storm Prediction Center issued a Day 4-8 Convective Outlook on Thursday warning that a “severe weather outbreak” is possible Sunday and Monday across portions of the Great Plains and Midwest. Forecasters said the setup could support tornadoes, very large hail and damaging winds over a large area.
While the exact location and timing of the strongest storms remain uncertain several days in advance, the long-range forecast has raised concerns that severe weather could eventually impact parts of Illinois with damaging conditions capable of disrupting schools and daily operations.
School districts across the state could be forced to close or delay classes next week if storms lead to widespread power outages, downed trees, flooding, road closures or structural damage. District officials often cancel classes during major severe weather events when bus routes become unsafe or school buildings lose electricity or internet service.
The Storm Prediction Center said a moist and unstable air mass is expected to develop across much of the Plains and Mississippi Valley Sunday into Monday as a powerful storm system moves eastward. Meteorologists warned the environment may become favorable for supercell thunderstorms capable of producing tornadoes and widespread wind damage.
Additional rounds of storms are also possible Tuesday through Thursday as a cold front slowly moves across the central and eastern United States. Forecasters said severe weather threats could continue each afternoon and evening during that period.
Because the threat is being highlighted nearly a week in advance, emergency managers and school districts may begin monitoring conditions closely over the coming days. Long-range outlooks predicting possible outbreak conditions this far out are relatively uncommon and typically indicate that forecasters are seeing strong agreement among weather models that a dangerous setup could develop.
Residents are encouraged to continue monitoring updated forecasts through the weekend as the timing and location of the greatest severe weather risk become clearer.
