Springfield, IL – Above-average temperatures are expected across central Illinois this week, with a noticeable warmup Tuesday before a late-week storm system brings a mix of rain and snow.
According to the National Weather Service in Central Illinois, Tuesday is expected to be the mildest day of the week, with afternoon highs climbing into the low to mid-50s across much of the region. This represents a significant departure from typical early February temperatures.
Monday will be cooler by comparison, with highs generally ranging from the low to upper 40s. Temperatures are forecast to dip slightly again Wednesday, with highs mainly in the low to mid-40s, before another system approaches.
Forecasters say the next storm system is expected to begin moving into central Illinois on Thursday, with rain and snow developing during the afternoon hours. While precipitation type may start as rain in some areas, any snow accumulations are more likely Thursday night, according to the NWS. No accumulation amounts were specified in the update.
Friday is expected to remain seasonable, with highs in the low to mid-40s, following the passage of the system.
Major travel corridors including I-55, I-72, I-74, and I-57 may see changing conditions late Thursday into Thursday night as temperatures cool and precipitation transitions. Motorists should be prepared for wet roads initially, with the potential for slick conditions if snow develops overnight.
The warmer temperatures early in the week may be most noticeable for commuters, students, and outdoor workers, especially Tuesday afternoon. However, residents are encouraged not to be caught off guard by the return of wintry weather late in the week.
Officials advise monitoring updated forecasts from the National Weather Service as timing and precipitation details become clearer.
