Good morning. Illinois. I'm Aaron Jolly. Step outside and you'll feel 57 degrees. Unseasonably warm. And about to get dangerous. We're tracking a severe weather outbreak this afternoon. Central Illinois is sitting in the bullseye — dewpoints climbing into the mid 60s, highs pushing 80 degrees. That's near-record territory for early March, springfield could tie its all-time high of 80 set back in 1955. But that warmth comes with a price. Starting around 6 P.M., thunderstorms fire up near the Illinois River. These storms mean business — large hail over 2 inches, damaging winds. And tornadoes. Some could be strong, EF2 or higher, there's an Enhanced Risk north of Springfield. South of that line, it's a Slight Risk. As the sun sets. Central Illinois sees mostly sunny skies this morning, then a 20 percent chance of storms after 4 P.M. High near 80. Tonight, those storms ramp up — 90 percent chance of heavy rain and thunderstorms. Low drops to 50. Chicagoland gets patchy fog this morning, then a 40 percent chance of severe storms this afternoon and evening. High only reaches 53 as cooler air filters in, tonight, storms continue with heavy rain likely. Low around 40. Northern Illinois mirrors that pattern — fog early, storms by late afternoon. High near 54. Tonight, thunderstorms likely. Low falls to 37. Wednesday brings cleanup. Rain and possibly wet snow showers taper off. Highs range from 41 in Chicago to 62 in Central Illinois before temperatures crash. Winds gust to 35 miles an hour. Thursday turns sunny with highs in the upper 40s to low 50s, friday brings another round of rain. The weekend stays unsettled with rain and possibly snow by Sunday as much colder air plunges in. Stay weather-aware this afternoon and evening, have multiple ways to receive warnings. Heavy rain could also cause localized flooding. Looking ahead. See you this afternoon.

Good morning. Illinois. I'm Aaron Jolly. Step outside right now. You're at 44 degrees. And we're just getting started. Today brings the kind of warmth that makes you forget it's still winter. Sunshine floods the state as temperatures surge to 72 degrees in Chicago with breezy southwest winds gusting to 30 miles an hour. Northern Illinois hits 71. Central Illinois steals the show — Decatur and Springfield climb to 76 degrees, threatening records set back in 1925. That's nearly 20 degrees warmer than usual for early March. Tonight stays mild. Lows only drop to the upper 40s to near 60 degrees. Warmer than some March afternoons. But here's where things flip. Tuesday afternoon brings serious weather. The National Weather Service has issued an Enhanced Risk — level 3 of 5 — for severe thunderstorms across northern Illinois. Storms fire up after 1 P.M. Tuesday, capable of producing large hail over 2 inches, damaging winds. And tornadoes. Central Illinois hits near 80 degrees before storms arrive. Northern areas stay cooler behind a morning cold front with highs in the low 60s. Heavy rain spreads statewide Tuesday night into Wednesday morning. Totals could exceed an inch, with localized amounts near 2 inches. Flash flooding is a concern. Wednesday brings lingering rain and cooler air — highs in the mid 40s to low 60s. Thursday clears out nicely near 50 degrees. Another round of rain arrives Friday, followed by an unsettled weekend with possible rain and snow mix. Enjoy today's warmth, but keep an eye on Tuesday. Storms could be strong. See you this afternoon.
