Good morning. Illinois. I'm Aaron Jolly. Wake up to a damp, mild start. But don’t get too comfortable. That 59-degree reading you’re seeing? It’s the calm before the change. A sharp cold front is slicing through Illinois right now. And by this afternoon, you’ll feel like you’ve jumped into a different season. Classic March—where spring teases you in the morning and winter reminds you it’s not done by lunch. Chicagoland starts at 60 degrees—yes, 60 in March—but that’s your high for the day. By noon, temperatures **plummet** to the mid-40s as the front blows through. Expect showers and even a few rumbles of thunder before 2 P.M., then clearing skies by evening. Winds howl out of the west-southwest at 15 to 20 miles an hour, gusting to 30. Tonight? A chilly 37 degrees—feeling more like late February than early March. Central Illinois sees a similar story but with a little more drama. Thunderstorms roll through before 11 A.M., packing gusty winds and brief heavy downpours. Highs crash from 63 degrees this morning to the low 50s by afternoon. Tonight, skies clear. And temps drop fast—down to 36 degrees. Sunday rebounds beautifully, though: sunny and 63 again. Up north, the front hits even harder. Rain showers give way to a steep temperature dive—from 58 degrees this morning to just 42 by afternoon. Overnight lows? A frosty 32. But don’t pack away the sunglasses just yet: Sunday brings sunshine and a rebound to 60. The big picture this week? A rollercoaster. Sunday and Monday deliver a taste of early spring, with highs in the 60s and 70s—yes, **70s** in March. But by Tuesday, another storm system arrives, bringing widespread rain, thunderstorms. And even a chance of wintry mix up north by Wednesday. We’re talking highs crashing back to the 40s, with some areas seeing rain **and** snow in the same day. Classic Illinois volatility. In One alert to note, a Flood Warning continues for the Little Wabash River near Clay City, where minor flooding is expected through Thursday. Avoid flooded roads—turn around, don’t drown. In Here's your heads-up for week ahead, sunday hits 60 statewide. Monday flirts with record warmth—mid-70s downstate, 64 in Chicago. Then Tuesday crashes back to reality—storms arrive, followed by a cooldown to the 40s. Thursday and Friday stay cooler, with a rain-snow mix lingering up north. In Oh. Here’s a bright spot, we’re **gaining nearly 3 minutes of daylight each day**. Spring equinox is just 13 days away—hang in there! Grab that extra layer tonight. You'll need it. See you tomorrow. Take care See you this afternoon.
Good morning. Illinois. I'm Aaron Jolly. If you stepped outside already, you walked into a wall of fog. Dense fog advisories are up statewide until 9 A.M. Visibility's down to a quarter mile in spots, especially south of I-27. Take it slow on the roads — this stuff is no joke. The good news? It lifts by mid-morning as warmer air pushes north. And warm is the word today. We're talking 27 degrees to 25 degrees above normal for early March. Chicago hits 68. Springfield climbs to 77. Even Rockford reaches 68 despite morning storms. That's the kind of warmth that tricks you into thinking spring's here early. But here's the catch. Multiple rounds of storms are coming. The first wave rolls through this morning between 7 A.M. and noon, mainly north of I-80. Scattered showers and thunderstorms, possibly some hail. Then this afternoon, conditions turn favorable for severe weather. West of I-55, there's a Slight Risk. East of I-55. Marginal. Large hail, damaging winds, even an isolated tornado are possible if storms fire up. Tonight's the main event. Another line of storms pushes through after midnight ahead of a cold front. This one could pack a punch — strong winds, heavy rain. And yes, a tornado threat exists. Some storms could be severe. Winds pick up too. Southwest gusts of 30 to 35 miles an hour this afternoon, especially behind any storms. Saturday morning, the cold front sweeps through. Lingering showers exit by midday, then we dry out. Temperatures crash from the 60s Saturday morning down to the 40s by evening. Sunday turns beautiful. Sunny skies, highs near 60. Monday climbs to the upper 60s. Then Tuesday and Wednesday, another storm system brings rain chances back. Keep your phone charged and stay weather aware tonight. See you tomorrow.

Good afternoon. Illinois. I'm Aaron Jolly. If you drove to work this morning, you probably felt like you were piloting a submarine. Dense fog rolled in overnight and it's sticking around, cutting visibility down to a quarter mile near Chicago and along the lakeshore. Take it slow out there. In the next 24 hours. Here's where things get interesting. Illinois is running two completely different weather programs today. Down in Chicagoland, you're stuck with that fog and clouds, barely scraping 39 degrees. Drive south to Central Illinois and suddenly it's a different season — mostly cloudy but hitting 61 degrees. That's a 22 degrees split across the state. Up north, the fog clears by mid-afternoon and you'll reach 50 degrees. Tonight, that fog comes roaring back. A warm front is lifting north. And after sunset, expect visibilities to drop below a mile statewide. Lows range from 37 degrees in Chicago to 52 degrees down south. Friday brings the heat. That warm front surges north, pushing highs into the upper 60s to mid 70s — near record territory for early March. But here's the trade-off: scattered showers and thunderstorms arrive Friday morning, especially north. Northern Illinois sees the highest storm chances between late morning and early afternoon. Winds gust to 25 miles an hour. Friday night, a cold front sweeps through with another round of showers and thunderstorms. Some storms could pack a punch, with damaging wind gusts possible. Rain tapers off Saturday morning. The weekend cools back down. Saturday brings drier weather with highs near 60 degrees. Sunday stays pleasant in the upper 50s to low 60s. Then Monday and Tuesday warm back into the 70s before another storm system arrives mid-week. Drive safe in that fog today. For the extended outlook, check the latest forecast as confidence improves. That's your forecast — we'll be back tomorrow.
Good morning. Illinois. I'm Aaron Jolly. If you stepped outside this morning and couldn't see your neighbor's house, you're not alone. Dense fog has swallowed much of the state overnight. Visibility's down to a quarter mile or less. And a Dense Fog Advisory runs through 9 A.M. For areas along and north of Springfield to Danville. Take it slow if you're commuting — that fog's thick as soup. In the next 24 hours. Southern Illinois is dealing with something more serious. A Flash Flood Warning stays active until 8 A.M. For Alexander. Johnson. Pulaski. And Union counties. We're talking 2.5 to 4.5 inches of rain already on the ground. If you're down there, stay off flooded roads. Chicagoland wakes up at 37 degrees under that gray blanket, barely climbing to 39 this afternoon with a chance of showers through midday. Northern Illinois starts warmer at 40 and reaches 50. Now down in Central Illinois? You're the winner today — 45 degrees this morning, climbing to 61 this afternoon. That's about 33 degrees warmer than we'd expect for early March. Tonight, fog redevelops as a warm front approaches. Lows hold in the upper 30s to low 50s. And if the fog clears in your area, you'll catch a Full Moon. Friday flips the script completely. Central Illinois surges to 78 degrees — more than 33 degrees above normal. Chicagoland hits 67. Northern Illinois reaches 69. But that warmth comes with a price — wind gusts over 25 miles an hour and likely thunderstorms by afternoon. Some could be strong Friday night. The weekend calms down. Saturday cools to the upper 50s and low 60s with clearing skies. Sunday brings sunshine and highs near 60. Monday warms back into the upper 60s and low 70s before our next system arrives Tuesday with more rain. Drive carefully in that fog this morning. For the extended outlook, check the latest forecast as confidence improves. That's your forecast — we'll be back tomorrow.

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.
