Illinois Weather March 4 Evening - 33° Above Normal

Good evening. Illinois. I'm Aaron Jolly. That mist on your windshield this morning? Just the opening act. A stalled warm front is cutting Illinois in half today, creating two completely different worlds. Dense fog has settled in. And visibility is dropping fast across the state. In the next 24 hours. Down in Central Illinois, you're sitting on the warm side of the line. Temperatures are hovering near 49 degrees right now. You climb to 63 degrees Thursday afternoon. Showers and thunderstorms roll through tonight, with up to a half inch of rain possible. Push north to Chicagoland. And the scene changes. The thermometer sits at 40 degrees and barely budges. Fog drapes the region while rain chances peak around 8 P.M. Tonight, lows hold steady near 40. Northern Illinois sees similar gloom. Patchy fog and scattered showers stick around. Your high tomorrow is just 50 degrees. That puts nearly 33 degrees between you and the southern part of the state. Tonight brings a Full Moon, but good luck spotting it through this overcast. Looking ahead. Friday delivers a jolt. Temperatures surge into the low 70s — nearly 33 degrees above normal for early March. Strong south winds gust over 25 miles an hour. Showers and thunderstorms develop. And a few could be strong Friday night. Saturday cools back to the upper 50s. Sunday looks sunny and pleasant near 60 degrees. Monday warms again into the upper 60s before our next storm system arrives Tuesday. Take it slow in the fog tonight. For the extended outlook, check the latest forecast as confidence improves. That's your forecast — we'll be back tomorrow.
