A heat wave is rippling through the country, with record breaking temperatures in Minnesota, Wyoming, Utah, and South Dakota.

Eastern half of U.S. braces for more long days of dangerous heat
MADISON, Wis. -- Tens of millions of people across the Midwest and East braced Sunday for another sweltering day of dangerously hot temperatures as a rare June heat wave continued to grip parts of the U.S. Almost all of the Northeast from North Dakota to Maine was under some type of heat advisory Sunday. So were parts of Arkansas, Tennessee, Louisiana and Mississippi. The temperature had already reached 80 degrees Fahrenheit (26.6 degrees Celsius) in the Chicago area by 7:30 a.m. Sunday, according to the National Weather Service. Forecasts called for heat indices of between 100 and 105 degrees F (37.7 to 40.5 degrees C). The heat index in Pittsburgh was expected to top 105 F. The temperature in Columbus, Ohio, was 77 F (25 C) at 8:30 a.m. Highs there were expected to reach 97 F (36 C) with a heat index around 104 F (40 C). Forecasts called for a heat index of 100 F in Philadelphia on Sunday, with a 108 F (42.2 C) heat index on Monday. The city's public health department declared a heat emergency starting at noon Sunday and ending Wednesday evening. Officials directed residents to air-conditioned libraries, community centers and other locations, and set up a 'heat line' staffed by medical professionals to discuss conditions and illnesses made worse by the heat. At Lincoln Financial Field, officials said each fan attending Sunday's FIFA World Cup match would be allowed to bring in one 20-ounce (0.6-liter) plastic bottle of water. Forecasters warned the heat index in Cromwell, Connecticut, would reach 105 F on Sunday, which could make life brutal for golfers Tommy Fleetwood and Keegan Bradley as they compete during the final round of the Travelers Championship. Cincinnati Reds shortstop Elly De La Cruz, playing against the Cardinals in St. Louis, and Seattle Mariners reliever Trent Thornton, facing the Cubs in Chicago, got sick Saturday while playing in the extreme heat. Sunday marked the second straight day of extreme heat across the Midwest and East Coast. Heat indices on Saturday hit 103 F (39.4 C) in Chicago and 101 F (38.3 C) in Madison, Wisconsin, turning that city's annual naked bike ride into a sticky and sweaty affair. Minneapolis baked under a heat index of 106 F (41.1 C). The actual temperature was 96 degrees F (35.5 degrees C), which broke the old record for the date of 95 F (35 C) set in 1910, according to the weather service. The heat is expected to persist into the coming week, with the hottest temperatures shifting eastward. New York City is expected to see highs around 95 F (35 C) on Monday and Tuesday. Boston is on track for highs approaching 100 F (37.7 C) on Tuesday, and temperatures in Washington, D.C., were expected to hit 100 F on Tuesday and Wednesday. Meteorologists say a phenomenon known as a heat dome, a large area of high pressure in the upper atmosphere that traps heat and humidity, is responsible for the extreme temperatures. Mark Gehring, a National Weather Service meteorologist in Sullivan, Wisconsin, said this level of heat is not uncommon during the summer months in the U.S., although it usually takes hold in mid-July or early August. The most unusual facet of this heat wave is the sheer amount of territory sweltering under it, he said. 'It's basically everywhere east of the Rockies,' he said, referring to the Rocky Mountains. 'That is unusual, to have this massive area of high dewpoints and heat.'

Wisconsin will see record-breaking heat through Monday night. How to stay safe and cool.
Wisconsin won't get relief from extremely hot and humid conditions until at least Monday night, when storms will move across the southwestern part of the state. The heat is likely to break records in several ways. The National Weather Service is forecasting temperatures will reach 97 degrees in Milwaukee today, which is the same record high for June 22 set in 1911. "It's going to be close. We could tie it, we could break it, we could be just short," said NWS meteorologist Mark Gehring. There's another important measure called the record high minimum — essentially, the warmest low temperature of a 24-hour period. Madison broke its record for that metric yesterday. In Milwaukee, that record was 73 degrees in 1921. The low temperature in Milwaukee this morning was 78 degrees, Gehring said, and setting a new record will depend on how much temperatures drop late tonight. "There's a very good chance that will happen," he said of breaking that record. That metric is important because it doesn't allow people to cool down in the overnight hours, Gehring said, especially when homes without air conditioning are warmer than outside temperatures.

A heat advisory remains in effect until 7 p.m. June 23 across Wisconsin for heat index values reaching up to 105 degrees. Milwaukee, Kenosha and Racine counties are under an extreme heat warning until 7 p.m. tomorrow, with heat index values reaching up to 110. The National Weather Service and health officials give the following tips to stay safe and cool. Stay hydrated with water or beverages with electrolytes. It's important to hydrate before going outside, not just while you're outside. Make sure you eat meals. Avoid alcohol and caffeine. Limit time outside if you can. If you need to be outside, take breaks in the shade. Wear a wide-brimmed hat, sunscreen and light-colored, loose clothing. Check on people without air conditioning, especially the elderly. The Milwaukee area has a map of cooling centers like libraries. Stay cool in your home by taking colder showers and baths and using wet towels to lower body temperature. Fans are useful but should not be your only cooling method. Know the signs of heat exhaustion, which include heavy sweating, weakness, dizziness, nausea and fainting. If you are experiencing any symptoms of heat stroke — which include high body temperature, dry skin, confusion and rapid pulse — call 911 immediately.

Here's where you can stay cool As extreme heat moves out, storms will roll in across southwestern Wisconsin, including over Madison by early Monday evening. The system will likely weaken before reaching Milwaukee. Rain chances continue essentially every day for the rest of the week. Right now, models show storms are hovering to the north and west of the Milwaukee metro area. "It's close enough that if it shifts just a little bit (to the south), Milwaukee could get rounds of showers and storms through the week," Gehring said. Those storms could involve severe weather not far from Milwaukee, he said, including wind and hail damage.
