Severe storms and strong winds are expected to sweep through the Chicago area and northwest Indiana on Thursday, with the highest risk for severe weather occurring in the late afternoon and evening. The National Weather Service in Chicago noted that while tornadoes remain a possibility, the threat is significantly lower compared to the March 10 storm outbreak. A powerful cold front is set to bring a sharp drop in temperatures, followed by drier, calmer conditions by the weekend. Live updates from FOX 32 Chicago Weather indicated that severe thunderstorm warnings were issued for parts of Illinois, Indiana, and Iowa, with the most active storms developing south of I-80. Ground stop alerts for O’Hare Airport were extended multiple times throughout the day, with delays lasting until midnight. The Storm Prediction Center classified the southern sections of Chicagoland as an Enhanced Risk level 3, indicating a high likelihood of strong storms producing large hail and damaging wind gusts. Scattered storms began forming late Tuesday afternoon, primarily south of I-88, with reports of lightning and small hail. Activity is expected to intensify through the mid-afternoon, peaking between 3 p.m. and 9 p.m. While tornadoes are considered unlikely, isolated tornadoes cannot be ruled out in areas south of the Kankakee River Valley. The National Weather Service emphasized that the primary threat remains large hail and strong winds, with localized flooding possible in southern regions. The severe weather is expected to subside by 10 or 11 p.m., leaving temperatures in the 40s by nightfall. A rapid temperature drop of up to 25 degrees could occur within a short period, creating a stark contrast across the region.#national_weather_service #storm_prediction_center #ohare_airport #fox_32_chicago_weather #kankakee_river_valley
Severe storms pummel parts of U.S. with snow, high winds, and risk of tornados A widespread and unpredictable pattern of severe weather swept across much of the United States on Sunday, bringing heavy snowfall to the Upper Midwest while damaging winds spread across the Plains. The storm system, which included the potential for tornadoes, created hazardous conditions, with roads becoming impassable in some areas. Forecasters warned of significant impacts, particularly in the mid-Atlantic states and Washington, D.C., where high winds and tornado threats were most likely. The National Weather Service issued alerts about a line of severe storms with damaging winds moving through the Eastern U.S. The storm system, which began on Sunday, was expected to cross the Mississippi, Tennessee, and Ohio valleys before heading toward the Appalachians and the East Coast. Officials predicted "severe thunderstorms with widespread damaging winds and several tornadoes" would affect the region. The area from South Carolina to Maryland was identified as the most vulnerable, with cities like Raleigh, North Carolina, Richmond, Virginia, and Washington, D.C., facing the highest risk. Schools in Raleigh and Chapel Hill, North Carolina, were closed on Monday as a precaution. Governor Josh Stein urged residents to enable emergency alerts on their phones ahead of wind gusts reaching 74 mph (119 kph). AccuWeather senior meteorologist Tyler Roys noted that major airports could be impacted by the storm, with wind gusts, blizzards, or snow contributing to disruptions. In the Upper Midwest, heavy snowfall was expected, with areas from central Wisconsin to Michigan’s Upper Peninsula likely to receive over 2 feet (60 centimeters) of snow.#national_weather_service #minneapolis_saint_paul_international_airport #ohare_airport #midway_airport #maui_county
