New York City is enduring a dangerous heat wave that is expected to persist through Saturday, July 4. An extreme heat warning is active for the city and its surrounding metropolitan area, forecasting high temperatures between 97 and 102 degrees. The humidity will make it feel significantly hotter, with heat index values potentially reaching 105 to 115 degrees.
This heat wave, the year's first major one, coincides with a busy Independence Day weekend. On Thursday, July 2, Central Park recorded 100 degrees, a mark not seen since 2012. Overnight temperatures are also expected to remain high, offering little respite. An air quality alert is also in effect for Friday, with ground-level ozone levels predicted to be unhealthy for sensitive groups.
However, a shift in weather is anticipated for Sunday, July 5. Showers and thunderstorms are forecast to move into the region, bringing a significant drop in temperatures to around 86 degrees. This change will signal the end of the oppressive triple-digit heat index values and provide much-needed relief to the city.
