Springfield IL Weather: Heat Wave to Bring 90s Through Next Week

Follow Us

If you’re living in central Illinois, get ready for a stretch of hot and dry weather. The National Weather Service in Lincoln has issued a heads-up for residents as temperatures are expected to climb into the 90s this weekend and continue well into next week.

With limited chances of rain, the region may see growing concerns for drought and heat-related impacts.

Thursday & Friday: Warming Up

The heat will start building by Thursday and Friday, with temperatures reaching the upper 80s. Expect mostly sunny skies and a dry atmosphere. There’s only a 15% chance of an isolated shower, but it’s not likely to bring any meaningful relief.

This is a good time to finish up any outdoor chores before the more intense heat sets in by the weekend.

Saturday Through Wednesday: Full-On Heatwave

The real heat kicks in on Saturday, when high temperatures will soar between 91°F and 95°F. The heat doesn’t let up through the early part of next week, with Sunday and Monday expected to hit highs close to 97°F in some areas.

Tuesday and Wednesday will stay hot, with temperatures hovering in the mid-90s

Overnight lows will stay warm, around mid-60s, offering very little cooling at night

That means air conditioners will be working overtime, and the lack of nighttime relief can increase health risks, especially for older adults and people with medical conditions.

Dry Conditions Could Hurt Lawns, Crops, and Events

Central Illinois has already been dealing with a prolonged dry spell, and this upcoming week won’t help. With rain chances sticking at just 15%, there’s little hope of meaningful moisture.

Here’s what this could mean:

Lawns and gardens may start browning quickly

Farmers may face more stress on crops

Outdoor events could become uncomfortable or even dangerous during the afternoon heat

Safety Tips for Residents

With the heat lingering over several days, it’s important to stay safe and plan ahead:

Stay hydrated – Drink water regularly, even if you don’t feel thirsty

Limit outdoor activity during the hottest hours (12 p.m. to 4 p.m.)

Check on elderly neighbors and anyone without air conditioning

Don’t leave kids or pets in parked cars—temperatures can skyrocket within minutes

Ensure pets and livestock have shade and plenty of water

No Relief in Sight—At Least Until Midweek

This hot and dry pattern is expected to stick around through at least Wednesday. There are no signs of major storms or widespread rainfall, and meteorologists don’t expect any big changes in the weather pattern in the short term.

Central Illinois is heading into a prolonged period of hot, sunny, and dry conditions, with temperatures peaking in the 90s through midweek. With almost no chance of rain, residents should prepare for continued drought stress, heat-related risks, and a need for extra caution during outdoor activities.

Stay cool, stay safe, and take steps now to handle the rising heat across Springfield and surrounding areas.
