Central Illinois is feeling the heat once again, with Springfield, Decatur, and nearby towns facing hot and muggy weather through early next week. According to the National Weather Service in Lincoln, temperatures will remain stuck in the mid-90s, and the humidity will make it feel even hotter. Residents are urged to take precautions to stay safe and cool, as outdoor conditions could become risky, especially during peak afternoon hours.
Sticky Evenings and Warm Nights
Saturday evening is expected to stay warm and sticky, with temperatures only dropping into the 80s overnight. There’s just a 15% chance of a thunderstorm, so most areas will remain dry but uncomfortable.
Sunday and Monday: No Relief from the Heat
Sunday brings more of the same — highs in the mid-90s and lows in the mid-70s. A 20% chance of isolated storms is possible, mainly during the late afternoon or early evening, but don’t expect much relief from rain. Monday continues the trend, with nearly identical temperatures and a 10% chance of storms hanging around into the evening.
What to Expect:
High heat index values due to humidity
Muggy nights offering little overnight cooling
Low storm chances, but not completely dry
Energy usage spike due to air conditioner use

Storm Chances Rise Midweek
While early week remains mostly hot and dry, storm chances are expected to increase by Tuesday and Wednesday, bringing some hope for rain and cooler air. Scattered thunderstorms are likely to develop midweek, but the heat won’t fully go away just yet.
