The oppressive heat dome affecting parts of the central and eastern U.S. is finally beginning to ease, following a record-setting stretch of high temperatures throughout June. The last few days have brought extreme heat to the Northeast, where seven states have either tied or broken their all-time June temperature records.
Among the notable records, Boston soared to 102 degrees, the highest June temperature seen in the city since 1872. Newark also reached a sweltering 103 degrees, matching its June record. According to weather expert Maxmiliano Herrera, the effects of this heat will linger for a while longer, especially in the mid-Atlantic and southern regions of the country.
As temperatures are expected to remain high one final day on Wednesday, several areas, including Baltimore, Philadelphia, and Richmond, Virginia, may set additional daily records. However, starting Thursday, the Northeast will experience a significant drop in temperatures, particularly in New England and New York, where readings could fall into the 60s and 70s by the end of the week.
Meanwhile, areas in the mid-Atlantic, Ohio Valley, and parts of the South will see gradual cooling or steady temperatures, remaining in the mid-80s to mid-90s range with high humidity, contributing to a continued summer feel.
It’s crucial during this heat wave to prioritize safety, as extreme heat is a leading weather-related cause of fatalities in the U.S. Checking on vulnerable individuals, such as the elderly or those without air conditioning, is essential. People are encouraged to limit their outdoor activities during the hottest parts of the day, stay hydrated, and dress in light, loose clothing to mitigate heat stress.
The sustained heat is largely due to a robust heat dome, a high-pressure system characterized by descending air that inhibits cloud formation and intensifies ground heating from the sun. Meteorologists predict this heat dome will slowly weaken over the coming days, leading to more comfortable conditions.
Overall, while the heat has posed challenges, relief is on the horizon, and understanding how to navigate these temperatures can help ensure the safety and wellbeing of affected individuals.
