The National Weather Service has issued a hazardous weather outlook for the Chicago area, warning of a significant fog risk and a limited thunderstorm risk today, particularly south of I-88 in Illinois and across northwest Indiana, as reported by NWS Chicago/Romeoville IL. Commuters are likely to face visibility issues early this morning due to dense fog, advisories caution that dense fog could also pose risks along the Lake Michigan shore later today and into the night.
Looking ahead to next week, Chicagoans should prepare for possible showers and thunderstorms with a limited flooding risk on Monday and a limited severe thunderstorm risk on Tuesday, the National Weather Service noted in its outlook. Furthermore, Wednesday and Thursday are forecasted to maintain a limited thunderstorm risk.
Rolling into the weekend, residents can expect mostly sunny skies with Saturday expected to hit a high near 73 degrees and sunshine continuing into Sunday with an estimated high of 70 degrees, according to detailed forecast by NWS. However, the risk for significant fog continues, particularly along the Illinois waters of Lake Michigan, restricting visibility for boaters and nearshore activities.
In line with the seasonal patterns indicating warmer temperatures for this time of year, an early week weather shift may bring storm activity on Monday and Tuesday, thereby disrupting the calmness of the preceding days, NWS Chicago reported via X. This change marks a shift from the predominantly dry and warm conditions in area so far, plausibly culminating in thunderstorms. A 40 percent chance of showers and thunderstorms is set to graze Chicago Monday after 1:00 P.M., with a high near 84 degrees.
Warmer than average temps will continue through early next week. Isolated showers and maybe a thunderstorm or two are possible well south of I-80 this afternoon, but most of the area will be dry. A pattern change provides the threat for storms Monday and Tuesday. #ILwx #INwx pic.twitter.com/WE2NlbYzwD
