A long-lasting heatwave is set to bring record-breaking temperatures to the eastern United States, with major cities such as New York, Philadelphia and Washington DC expected to see unprecedented heat for April. Forecasters predict highs of 93°F (33.9°C) in the capital on Wednesday and Thursday, with the unusual weather pattern persisting into the weekend.
The heat is notable not only for its intensity but also for its duration, which experts describe as 'borderline unprecedented' for this time of year. Senior meteorologist John Feerick of AccuWeather.com said records would be challenged from Georgia to the New York City area and back towards the Ohio valley. The National Weather Service projects 86°F in New York's Central Park, just shy of the 1941 record, while Philadelphia may hit 92°F and Atlanta 88°F.
Despite the high temperatures, humidity levels are not as high as in summer, making it feel less oppressive. However, the early-season heat can be more stressful on bodies unaccustomed to such warmth, and heat is the leading weather-related killer in the US. Vulnerable groups include infants, older adults, and those with chronic conditions.
The heatwave follows severe storms that struck Kansas, Minnesota, Wisconsin, and Michigan earlier in the week, damaging buildings including the historic Yost Ice Arena in Ann Arbor. The ridge of high pressure responsible for the heat is expected to break down by Sunday as a cold front moves east, bringing 'pleasantly cooler' conditions by Monday.
