Portland's Weather Outlook: From Rain to Heat Wave

Portland, Oregon, may experience its first 100-degree day of the year between August 13-15, with a 50% chance according to the National Weather Service. While forecasts beyond five days are uncertain, a building high-pressure system is expected to bring hot temperatures in the 90s to the Pacific Northwest. If the Portland International Airport reaches 100 degrees, it will be the first time this year, although other parts of the region have already experienced such temperatures.
