Springfield, IL – Cloudy skies, light drizzle, and cool temperatures are shaping today’s weather pattern across central Illinois as a widespread gray stretch continues into the weekend. Morning mist has created slick patches on roads, with temperatures holding between 47 and 52 degrees through the morning and early afternoon.
Residents across Springfield, Decatur, Peoria, Bloomington, and nearby counties can expect skies to stay overcast for much of the day as moisture lingers over the region.
Increasing Rain Chances Through Friday
Forecasters at the National Weather Service in Lincoln, IL say that a more organized storm system will begin lifting into the state late Thursday, significantly increasing rain chances.
Rain probabilities rise to 50–80%, with the highest likelihood across southern portions of central Illinois.
By Friday afternoon and Friday night, measurable rainfall becomes more likely as atmospheric moisture deepens over the region. This could slow evening travel across major corridors, particularly where drizzle transitions to steadier rainfall.
Temperatures Stay Cool as System Arrives
Daily temperatures will remain consistent with seasonal norms.
- Today: Upper 40s to low 50s, periods of mist and drizzle
- Thursday: Mid-50s with scattered showers developing late
- Friday: Highs near 56 degrees, overnight lows in the low 40s
The developing system may also bring patchy fog in low-lying areas, adding to reduced visibility during early or late travel hours.
Friday Expected to Be the Wettest Day
Weather models indicate that Friday will carry the most significant rainfall potential. Forecasters expect off-and-on showers throughout the day, possibly lasting into the night as the system moves across the region.
Road conditions may become slick, and drivers are encouraged to allow extra time during the Friday evening commute.
Weekend Outlook Shows Gradual Improvement
Saturday brings the first signs of drying as rain exits and skies begin to gradually clear. Temperatures will reach the lower 50s, though lingering clouds may persist through the first half of the day.
Sunday offers the best weather of the extended forecast, with highs climbing into the upper 50s and lower 60s. After several cloudy days, central Illinois may finally see extended sunshine before another pattern shift early next week.
What Residents Should Expect Today
Residents should be prepared for:
- Intermittent drizzle through the morning and afternoon
- Reduced visibility in patchy areas
- Cooler temperatures with little variation
- Increasing rain chances by Thursday night
The National Weather Service notes that travelers should monitor updated forecasts as the system approaches, especially those driving during peak commuting hours on Friday.
