HEAT ADVISORY ISSUED FOR MONDAY (1PM-8PM) FOR DODGE, FOND DU LAC, JEFFERSON, WALWORTH, WASHINGTON AND WAUKESHA COUNTIES. 

Dangerous heat is on the way to SE Wisconsin in the days ahead. The warmth and humidity is already building and will peak both Monday & Tuesday afternoon.
The National Weather Service has issued a Heat Advisory effective 1pm-8pm Monday for Fond du Lac, Washington, Dodge, Jefferson, Waukesha and Walworth counties.

Meantime, the warmth and humidity are getting an early start on Sunday. Overnight lows have only fallen into the 60s. Highs top out in the mid/upper 80s. Heat index values could reach into the lower and mid-90s.

The worst of the heat arrives Monday and Tuesday. Highs top out in the lower and mid 90s – with hotter conditions farther away from Lake Michigan.
Heat index values could reach 100-105° away from the lake. Given the hot, humid and unstable environment, there is a low chance for storms across SE Wisconsin both Monday and Tuesday. Storms will be limited by hot air aloft (a cap). If storms are able to break through the cap, they could quickly become severe – bringing downpours, damaging winds and hail. There is a Marginal (Level 1) risk of severe weather late Monday into early Tuesday.

A Slight (Level 2) risk of severe weather is in place for Tuesday. As a cold front approaches from the West, storms may fire in the vicinity of the front. If they are unable to form (which is also possible), heat index values could reach or exceed 105° in some spots on Tuesday afternoon. The NWS has indicated they may expand heat headlines towards Milwaukee on Tuesday.

After the cold front passes, temperatures moderate later in the week. Another frontal boundary brings showers/storms by late Thursday into Friday.

MADISON — Wisconsin Manufacturers & Commerce (WMC) — the combined state chamber and manufacturers’ association — and Johnson Financial Group are again partnering to host a contest to determine the ‘Coolest Thing Made in Wisconsin.’ The popular competition highlights Wisconsin’s robust manufacturing industry, which contributes over $71 billion in total economic output to the state. This year, the contest organizers are refreshing the program with a new logo and rebranded website as a nod to the modernization of the manufacturing industry as a whole. The ninth annual contest will culminate by crowning a Wisconsin-made product as the Coolest Thing Made in Wisconsin.

“Wisconsin is home to nearly 500,000 men and women who are employed by our thousands of manufacturers,” said WMC President & CEO Kurt R. Bauer. “This contest highlights not only the cool products made in our state, but also the entrepreneurship and work behind each product. Our manufacturers are the best in the country, and we have a great opportunity to underscore their contributions to our economy, the high-paying careers they create, and the innovative, necessary products they make.”

Any product that is manufactured in Wisconsin qualifies for the contest, and nominations will be accepted starting on Aug. 19 at the new website, www.madeinwis.com. 

WMC and Johnson Financial Group have partnered together for this contest since 2016, and Wisconsinites have cast over one million votes since its inception. Over a thousand products representing a wide array of industries have been nominated over the years, and winning products have included beverage dispensers, firetrucks, cranes, motorcycles, military vehicles, robotic carts, rifles, and even kringle.

Following the nomination period from Aug. 19 through Sept. 6, a popular vote will determine the Top 16 products that will be placed in a bracket-style tournament called Manufacturing Madness. Products will compete against one another in head-to-head matchups, and the products that receive the highest votes in each matchup will advance to the next round. Manufacturers, consumers, employees and other Wisconsinites are encouraged to vote once per day, per device through the rounds of voting.

This year’s Coolest Thing Made in Wisconsin will be announced at WMC’s Business Day in Madison event on Oct. 17.

Eight lakeshore Wisconsin counties are under an air quality advisory for potentially unhealthy ozone levels until 11 p.m. Saturday. Children, older adults, people working outside and those with lung or heart ailments are encouraged to take precautions for their health, according to the Wisconsin Department of Natural Resources.

Here’s what to know:

Ozone advisory issued for eight counties, including Door, Milwaukee, Racine

The DNR issued an ozone advisory from 2 to 11 p.m. in Milwaukee, Kenosha, Racine, Ozaukee, Sheboygan, Manitowoc, Kewaunee and Door counties.

The DNR has advised that the air quality in all eight counties may reach the “Unhealthy for Sensitive Groups” level before the warning subsides.

“People with lung ailments (such as asthma), heart disease, children, older adults, and people who are active outdoors (including outdoor workers) should reduce prolonged or heavy outdoor exertion,” said a news release from the DNR.

How should people in sensitive groups take precautions during the air quality advisory in Wisconsin lakeshore counties?

It’s OK for people in the groups sensitive to the air quality at this level to be active outdoors, but take more breaks, the National Weather Service advises. Be sure to watch for symptoms such as coughing or shortness of breath.

People with asthma are also advised to keep quick-relief medicine handy, according to the NWS.

People with heart disease should contact their health care provider if they experience symptoms such as palpitations, shortness of breath or unusual fatigue. That may indicate a serious problem, the NWS said.

What is the Air Quality Index in Southeastern Wisconsin?

The Air Quality Index is broken into six colored categories on a 0-500 scale, and when readings get above 100, air quality becomes unhealthy for certain groups, according to a previous Journal Sentinel report. AN AQI level between 101 and 150 is in the “Unhealthy for Sensitive Groups” category.

Shortly after 3: 20 p.m., Milwaukee, Racine and Kenosha counties had all reached that level. Milwaukee County was at an AQI level of 105, Racine was at 118 and Kenosha had reached 119, according to the Wisconsin Air Quality Monitoring Data map.

The other counties were at “Moderate” and “Good” levels at about the same time, according to the DNR map. However, they remain under an advisory as the potential remains for readings to rise. Ozaukee reached an AQI level of 86, and Sheboygan was at 87, the map showed.
