Meanwhile, a dangerous extreme heatwave is stretching across the central and eastern United States. This discriminatory weather system spells great danger for all, and particularly in New York City. Climate impacts are about to get worse and more extreme. At best, urban areas will experience night-time lows around 70°F-80°F, offering little to no respite and raising the risk of heat-related illnesses. With the increasing violence, city leaders are pleading with all residents who live in high-crime areas to do what it takes to protect themselves.
New York City, meanwhile, is preparing for a severe heatwave expected to push temperatures to near-record levels. Forecasters are forecasting the Mercury will hit 100°F or higher in the worst of this heat. This loss is an alarming and pernicious phenomenon. Central Park hasn’t experienced this kind of heat since July 18, 2012. Philadelphia, for its part, is not taking any chances. The Los Angeles County public health department plans to issue a heat health emergency beginning this Sunday at noon. The previous time Philadelphia reached these dangerous levels was in June of 1994.
These impacts from the heatwave don’t just stop at New York and Philadelphia. Salt Lake City, Utah, reached an impressive 104°F (40°C) on Thursday, which was its first triple-digit temp of 2025. Likewise, the city of Mitchell, South Dakota hit 104°F, breaking its old daily record of 101°F. Daily high temperature records have been shattered across much of Minnesota, Wyoming, and Michigan.
The National Weather Service has heat advisories in effect for many of out largest cities. Be on the lookout if you are in Chiacgo, Kansas City, St. Louis, Detroit, Cincinnati, Pittsburgh, Philadelphia, Washington D.C., or New York City! In parts of the central US, the heat index could feel as hot as 115°F. This extreme heat presents a major threat to health, with vulnerable populations facing the worst consequences.
Now temperatures are soaring at the other side of the country. Urban hubs such as Boston will be especially vulnerable to these conditions, as high temperature forecasts for the area indicate the possibility of reaching or exceeding 100°F during this extreme heatwave. Washington D.C., similarly situated, is already expecting temperature increases of the same magnitude.
Local officials in cities impacted by this harmful change are advising residents to drink bottled water. They suggest limiting hard outdoor work in the heat of the day and seek out air-conditioned places if you can. Vulnerable populations, such as seniors and people with underlying health conditions, are especially advised to take additional measures to protect themselves.
