Chicagoans flock to city's beaches to beat the extreme heat
Summer in Chicago started off with oppressive, dangerous heat as temperatures topped out above 90°, with the heat index climbing well above 100° on Saturday. The lakefront was crowded, and so were public pools, as crowds headed out to keep cool by taking a dip anywhere they could. "I am doing a plein air painting," Kira Mountjoy-Pepka said along the lakefront. "It means painting outdoors and capturing the light exactly as it is." As an artist captured Chicago's light and shadows, the heat left an impression on everyone. "Hopefully, I'll get out of here before I melt and turn into a puddle," Mountjoy-Pepka said. She painted in plein air that felt like 100° and rising. During an extreme heat warning with dangerously hot and humid conditions, people like Allison Vega flooded places like Millenium Park. "Kids are running around in their bathing suits, just laying on the ground in the dirty water, but they're cool. So, that's what matters. They're happy and they're cool," she said as her kids played in Crown Fountain. Bodies of water, no matter how big or small, were the place to be on Saturday. Buddies Zach Frame and Parker Greenfield beat the heat and the crowds at Humboldt Park Beach, the city's only inland beach, avoiding the larger crowds on the lakefront while still managing to find sand and sun. "I feel like we kind of skipped spring and went right into summer and then it hit pretty hard," Frame said. Chicago was sweltering, but the Windy City offered some brief relief. "The breeze definitely helps," Frame said.

'At Least' Three Dead After Tornado Outbreak Slams U.S. State
'At Least' Three Dead After Tornado Outbreak Slams U.S. State originally appeared on The Spun. While most of the United States is dealing with a heatwave this weekend, one region is picking up the pieces from a deadly tornado outbreak. On Friday, tornadoes with 100+ mph wind gusts were detected in North Dakota and Minnesota. There were plenty of power outages reported last night, but the main concern is that North Dakota lost a few lives. According to ABC News, at least three people died in the rural town of Enderlin. The Cass County Sheriff's Office was dispatched at around 11:40 p.m Friday to assess the damage. Before they arrived at the scene though, storm chasers found two deceases people. The death total increased to three shortly after. "Shortly after learning of this, the Enderlin Fire Department was dispatched to another location, and a third deceased person was found as a result of the tornado," the Cass County Sheriff's Office said. "Deputies found extensive damage to the area and began conducting well-being checks on people with several partner agencies. Law enforcement, the Enderlin Fire Department, and other first responders continue searching the area and checking on residents now." The National Weather Service has not yet rated Friday night's tornadoes. "We can't really rate it until we see what kind of damage it produced," National Weather Service meteorologist Timothy Lynch said. "However, from what I saw on radar and first hand accounts that were sent to us via video, they look like they could potentially be very strong tornadoes. Radar-indicated winds upwards of 110 miles-per-hour and several reports from NDDAWN, personal weather stations reported 80, 90, 100 miles-per-hour winds." The National Weather Service usually issues life-saving warnings before tornadoes strike in the United States. Here are some tips in the event a tornado pops up in your town: Listen to local news or a NOAA Weather Radio to stay informed about tornado watches and warnings. Have a family plan that includes an emergency meeting place and related information. Pick a safe room in your home, such as a basement, storm cellar, or an interior room on the lowest floor with no windows. Conduct a family severe thunderstorm drill regularly so everyone knows what to do if a tornado is approaching. Consider having your safe room reinforced. Encourage your loved ones to prepare for the possibility of tornadoes. Tornado season usually ends in June, but it's possible it'll linger a bit longer this year.
