Weather Chicago: Storm rounds, fog, and airport disruptions set the tone heading into Saturday
weather chicago is entering a volatile stretch Friday into early Saturday, as fog and several rounds of showers and thunderstorms raise the risk for hazardous travel, potential severe weather impacts, and air-traffic disruptions across the metro area.
What Happens When Weather Chicago brings multiple storm rounds on Friday?
Forecasters are tracking several waves of showers and thunderstorms moving through Chicagoland on Friday, starting with a morning cluster that is expected to cross the area early in the day. The severe potential with the morning activity is described as relatively low, but impacts are still possible, including hail and gusty winds.
Conditions remain unsettled beyond the morning round. Isolated thunderstorms are possible Friday afternoon and evening, with risks that include high winds and hail. A low-end tornado threat is also noted for later Friday, while the broader expectation centers on wind and hail as the main concerns.
Storm chances do not end with daytime hours. Friday night into Saturday morning, a scattering of showers and thunderstorms is expected before 8 a. m., and those storms could also become severe. The threat is characterized as low, with high wind identified as the biggest concern in that overnight-to-early-morning window.
What If fog and storms collide with commutes and visibility?
Friday begins with fog that may be especially impactful near Lake Michigan, where visibility can drop sharply and make travel hazardous. Dense Fog Advisories are in effect for most of Chicagoland through 10 a. m. Friday, with expectations that the fog clears in the hours ahead even as storm chances continue.
The timing of storms adds another layer of concern for commuters. The first round is expected to arrive during rush hour Friday morning, increasing the likelihood of a difficult trip for drivers and transit riders navigating low visibility and active weather at the same time.
During heavier storm cells, hazards can include heavy downpours, lightning, and small hail. Forecast messaging also points to the possibility of a break between storm rounds, followed by additional development by mid to late afternoon. In those later storms, hail, gusty winds, and drenching downpours stand out as primary threats, while tornado chances are described as extremely low but not zero.
Temperature behavior may also feel unusual during the day. After the morning activity, readings are expected to fall through the afternoon behind a gusty cold frontal passage, with the day’s high occurring early in the morning rather than later in the day.
What Happens When thunderstorms trigger airport ground stops?
Air travel has already felt the impact of Friday’s conditions. The Federal Aviation Administration issued ground stops at O’Hare and Midway Friday morning tied to thunderstorms and fog.
At O’Hare, thunderstorms prompted the FAA to halt landings and departures around 8 a. m. The ground stop remained in effect until 9: 30 a. m., when it was replaced by a ground delay. Delays averaged 167 minutes at the airport during that period.
At Midway, a ground stop was issued around 9: 12 a. m. due to fog, with an expiration time set for 10: 30 a. m. Flight cancellations were also reported over the prior 24 hours: 76 at O’Hare and 20 at Midway.
With storm chances continuing through Friday and into early Saturday, travelers should be prepared for additional disruptions if thunderstorm activity and visibility issues persist. weather chicago remains a close watch for anyone with flights, airport pickups, or time-sensitive travel plans.
