Looks like a significant pattern change is coming across North America as we reach the second week of August.
The hot/dry pattern over the Pacific Northwest and British Columbia should get replaced by a more typical west to east flow of air off the Pacific, which will allow some fronts to bring some rainfall starting late next week and the following week.
Cooler and wetter weather should also make a return to Atlantic Canada late next week, but it may not last too long as there are signs of another very warm/humid pattern shaping up after the 12th.
Mid-August should bring more typical summer weather to eastern Canada, which is good news for those who have been just staring and not swimming in their pools.
