A significant heat wave is impacting large regions of the United States and Canada, leading to extreme temperatures and deteriorating air quality.
High temperatures that began on Tuesday are set to persist into Wednesday across Toronto and various Canadian cities, alongside extensive areas in the Midwest and Northeastern United States. Meanwhile, millions of Americans are enduring intense heat further west.
Advisories are currently in effect for millions in cities like Boston, New York City, Philadelphia, and as far west as Buffalo, New York, continuing through Wednesday.
This heat wave follows a record-setting blast of heat that swept through much of the United States on July 4, prompting experts to caution the public to exercise vigilance.
A strong area of high pressure is building eastward, covering parts of the United States and Canada, creating a dome of hot, humid air.
This heat dome has already shattered temperature records in Montana and Utah, and its effects are now shifting eastward.
In Chicago, temperatures are projected to hit 97°F (36°C) on Wednesday, with the northern Plains, Midwest, and Northeast expected to bear the brunt of the heat.
New York City might see temperatures soar to 100°F, while Washington, DC could hit an even sweltering 102°F. In certain locations, conditions could feel even hotter due to high humidity.
Central and eastern Canada are also experiencing warmer days, though a cold front is anticipated to bring some relief in the coming days. Severe thunderstorms are also on the horizon, potentially impacting areas in New England.
By week’s end, thunderstorm conditions are likely to expand across a broader area of eastern North America, alleviating some of the heat, although many regions will still experience temperatures above seasonal norms.
