Current Heatwave Expands Across US and Canada
A strong area of high pressure in the upper levels of the atmosphere is building eastwards across the US and parts of Canada.

[1] At the same time, New York could reach 100F while Washington DC is expecting 102F. [1] A few places could get even hotter, with high humidity making it feel even more uncomfortable. [1] Toronto and other Canadian cities as well as parts of the US Midwest and Northeast will see the high temperatures that started on Tuesday continue into Wednesday. [1] Central and eastern areas of Canada have also been hot, but a cold front is set to bring lower temperatures over the next few days.
