Weekly weather pattern update

The core of the heat is likely to be focused across the western two-thirds of North America over the next couple of weeks. There will likely be a decent cooldown with lower humidity across eastern Canada, the Great Lakes and the Northeast United States late next week till about Aug. 15, when it will start to warm up again, but not to the extent of what we will see farther west.

The southwest U.S. monsoon will likely continue to be active much of this month, which may, in turn, lead to below-normal rainfall across southwestern Canada.
