CHICAGO, ILLINOIS — Scattered showers are moving through the greater Chicago metro area and surrounding communities this Friday morning as a strong disturbance tracks to the south of the region. Radar at 10:22 a.m. shows widespread green returns stretching from Rockford and Sycamore eastward through Schaumburg, Geneva, Aurora, Joliet, and into Chicago, Evanston, and Waukegan along the lakefront.
Today will be unusually cool for late June, offering residents a final comfortable day before a dramatic pattern change arrives. The heat dome begins building in Sunday before becoming powerful and potentially dangerous by Monday.
Showers Covering Wide Area From Rockford to Chicago Lakefront
The disturbance pushing showers through the area this morning is producing widespread light to moderate rainfall across a broad swath of northern Illinois. Coverage extends from Rockford and Oregon in the west through Sycamore, Geneva, Schaumburg, and Aurora before reaching Chicago, Evanston, and the lakefront communities of Waukegan and Kenosha to the north.
Today Offers Unusually Cool and Comfortable Conditions
Friday is shaping up to be unusually cool for this time of year, representing a welcome break from summer heat for residents across the Chicago metro and surrounding communities. Those who prefer cooler weather are encouraged to enjoy today’s conditions, as this comfortable pattern is short-lived with a significant change on the way.
Heat Dome Arrives Sunday and Builds Through the Weekend
The comfortable Friday pattern gives way quickly as a heat dome begins to push into the region Sunday, bringing temperatures and humidity levels back to levels more typical of a dangerous summer heat event. The transition from today’s cool and showery conditions to Sunday’s heat dome arrival will be rapid and noticeable.
Heat Becomes Powerful and Dangerous by Monday
Forecasters are emphasizing that the heat dome does not just arrive Sunday but becomes significantly more powerful and intense by Monday. Residents across the Chicago metro including Naperville, Aurora, Joliet, Schaumburg, and Rockford should begin preparing now for what is expected to be a dangerous heat event developing early next week.
