Wildfire Smoke Blankets Northeast as Heat Dome Bakes Region

A sprawling heat dome is driving temperatures into the danger zone across the Northeast while pushing Canadian wildfire smoke eastward over millions of residents.

A heat dome is trapping dangerously high temperatures across the northeastern United States as of Wednesday, July 15.
Wildfire smoke from Canada is being pushed eastward by the same weather system, degrading air quality across the region.
New York City and surrounding metro areas are among the areas affected by both the heat and the smoke.
Officials in multiple states have opened cooling centers as the compounding conditions raise public health concerns.
The heat dome is expected to persist through the coming days with little immediate relief in the forecast.

A heat dome is sending temperatures spiking across the Northeast on Wednesday while simultaneously funneling Canadian wildfire smoke into the region, creating a compounding public health emergency stretching from Minnesota to New York City.

The high-pressure system is trapping hot air at the surface and driving conditions into the danger zone across millions of square miles, according to meteorological reporting reviewed by the Wail.

Smoke from active wildfires in Canada is riding the same atmospheric current eastward, dropping air quality to unhealthy levels in multiple major metro areas. New York City is among the affected cities.

Cooling centers have opened in several states as health officials urge residents — particularly the elderly and those with respiratory conditions — to stay indoors during peak afternoon hours.

The National Weather Service has issued heat advisories and air quality alerts covering large portions of the region. Forecasters expect the heat dome to hold through at least the end of the week, with conditions unlikely to break before the weekend.
