It was a chilly start as June began for some areas in Chicagoland, with temperatures as low as the upper 30s during Sunday's sunrise.
But that's changing quickly.
We're set for plenty of sun Sunday, though it could be hazy due to the Canadian wildfire smoke that's being blown into our area by northerly winds.
Those winds will gradually shift to southeast, however, so temps will rise to the low 70s inland by Sunday afternoon, though it'll be closer to the mid-60s at the lakefront.
By Monday, winds will be out of the southwest and gusty, which will send temps into the mid-80s. Some areas of Chicagoland could then see temps close to 90 for what's expected to be a hot, humid Tuesday (see more below).
There was no Air Quality Alert issued for the Chicagoland area as of late Sunday morning, which is good news, though skies could continue to be a bit hazy at times due to the Canadian wildfire smoke that's been directed into the Chicago area since about Friday.
The NOAA-GOES-19 satellite image depicts the area of smoke in the lighter gray shading which nearly encompassed all of Minnesota and Iowa on Friday.
Dozens of large, out-of-control wildfires continue burning across Canada. They're depicted on the map below, as of Friday.

The extended outlook calls for south/southwest winds to drive our temps to near 90 on a muggy Tuesday, with possible late-afternoon and evening showers or thunderstorms.
Wednesday then looks pretty soggy, with highs in the mid- to upper 60s and a chance of isolated thunderstorms. We dry out on Thursday and should see temps in the seasonal 70s by the afternoon.
We had a cool start to the weekend across the Chicago area, but it won't last long as temps rebound quickly by later Sunday, with a return to summerlike warmth early next week.
Dry weather takes hold for several days before the next chance of showers and thunderstorms arrives late Tuesday into Wednesday as a cold front slides through the area.
The image below tracks the arrival of several weather systems and multiple chances for rain during the upcoming week.
Some beneficial rainfall is possible for the Chicago area, with even heavier totals forecast across the south Central Plains.
A large portion of the Chicago metro area now sits in 'moderate drought' conditions. The area of moderate drought statewide grew from just over 17% a week ago to nearly 23% in the latest outlook.
May 2025 was quite dry for much of the state.
Many areas saw less than half of their normal rainfall, with 2-4-inch deficits for the month pretty common.

Study finds common dietary supplement can flush out toxic forever chemicals from your body
Eating a fibre supplement derived from oats before each meal could flush out toxic forever chemicals from the body, a new study suggests. Per and polyfluoroalkyl substances, or PFAS, commonly known as forever chemicals, are widely used to make products like non-stick cookware, cosmetics, stain-resistant fabrics, firefighting foams, food packaging, and waterproof clothing. They persist in the environment for hundreds of years and are increasingly linked to a range of health conditions in humans, including decreased fertility, developmental delays in children, and a higher risk of some cancers. Scientists have been seeking ways to remove them from the body and the environment or degrade them into harmless compounds. 'Despite the growing concerns about the toxicity of PFAS, specific interventions to reduce PFAS levels in the body are limited,' the study notes. 'Current clinical treatments to reduce PFAS body burden are minimal.' Previous studies have shown that beta-glucan fibre molecules found in oats, barley and rye can bind to PFAS in the digestive system. The latest study, published in Environmental Health, finds that consuming a dietary supplement with beta-glucan fibre could significantly reduce PFAS levels in the body. Researchers recruited 72 Canadian men aged 18 to 65 with detectable levels of PFAS in their blood and fed 42 of them a diet supplement of one gram of oat beta-glucan, a type of soluble gel-forming fibre, before each mealtime, when the body produced the most bile. The remaining 30 participants received a placebo made of rice. 'Serum samples were collected from 72 participants in 2019-2020 at baseline and after four weeks of the intervention and were analysed for 17 PFASs,' the study states. After four weeks, researchers found a nearly 10 per cent drop in two of the most dangerous PFAS types in people who took the oat fibre supplement. The two forever chemicals, known as PFOA and PFOS, have been detected in drinking water, food packaging and cosmetics, and they can build up in the body over time. Although the results are modest, scientists say the findings offer a first step to formulating a dietary intervention for removing PFAS from the body. 'Results from this pilot analysis suggest a potentially practical and feasible intervention that may reduce human body burdens for some PFASs,' they say. 'However, studies utilising a larger sample with a broader range of serum concentrations, longer intervention period and clinically relevant fibre intakes are needed to determine the efficacy of using gel-forming dietary fibres to increase PFAS excretion.'

No hurricane season? Acting FEMA chief's remark was a joke, DHS says.
The acting head of the Federal Emergency Management Agency was joking when he said that he didn't know the United States had a hurricane season, a spokesperson for the Department of Homeland Security, which includes FEMA, said on Monday. David Richardson's comment to staff at a briefing on Monday was first reported by Reuters and drew swift, concerned reactions from Democratic lawmakers. The Atlantic hurricane season began Sunday and ends Nov. 30, with a 60 percent chance of above-normal activity this year and three to five major hurricanes expected, according to the National Oceanic and Atmospheric Administration.

Hazy outlook: Smoke, dust likely to impact US skies this weekend
Noxious wildfire smoke from Canada will infiltrate the U.S. through the north this weekend, just as African dust clouds approach from the east. They have nothing to do with the Trump tariffs and might not be as ominous as it sounds, but their presence will be noticeable. Meteorologists are especially keeping track of the smoke, emanating from wildfires in Canadian territory from British Columbia to Manitoba, which have the potential to cause health problems in American soil. Smoke has already been detected drifting in through Montana, North Dakota and northern Minnesota, where air quality alerts have been issued. The smoke is expected to spread across the upper Midwest on Friday and Saturday before heading southeast, where cloud cover would minimize its impact. While not on the same scale as the spring and summer of 2023, when 800-plus Canadian wildfires burned more than 40 million acres and blanketed large swaths of the U.S. Midwest and East with a gray haze, the current spate of approximately 150 blazes will have an extended impact across the border as the wind blows southeast. Major population areas in and around Chicago and Milwaukee will likely be in the smoke's path, and possibly Detroit and Indianapolis as well. 'We will see more smoke across parts of the Midwest, even down into portions of the Ohio Valley by Sunday,'' AccuWeather meteorologist Elizabeth Danco said. 'We are expecting some of it to get down into some of the lower levels of the atmosphere, which could cause some reduced air quality and some health hazards, especially for those with respiratory issues.'' How acute those become could be determined by the smoke's elevation in the atmosphere. At lower levels it can not only cause breathing difficulties but also impair driving visibility. When remaining high, the haze actually leads to vibrant sunrises and sunsets. That same phenomenon may be on display with the appearance of the Saharan dust clouds, which are fairly common this time of year. The first of two large ones is primed to arrive this weekend and is aiming for Florida and the Gulf Coast, in addition to the Caribbean, parts of Mexico and most of Central America, AccuWeather said. The second one is even bigger and will likely cover all of Florida and most of the gulf by Thursday morning, according to the outlet. Danco said neither one figures to present a health threat or affect air quality because they will mostly remain at high levels in the atmosphere. Dust clouds can actually have the beneficial effect of inhibiting storm formation or development because they carry such dry air, the opposite of what nourishes weather systems like hurricanes. In addition, the hazy skies they create can be quite vibrant as the sun rises and sets. 'They have a nice orange hue to them,'' Danco said. 'It's really cool to see the sky. There should be some good pictures coming out.'' This article originally appeared on USA TODAY: Hazy outlook: Smoke, dust likely to impact US skies this weekend
