Setting a record high temperature and new record for most 90 degree days in a summer is a foregone conclusion Tuesday.
Portland will easily reach 90 degrees today, making it the 25th day this summer that the thermometer has reached that mark. We are currently tied at 24 days with summer 2009 for most days of 90+ degrees. The heat has prompted a Heat Advisory to begin at 11 a.m. that encompass much of western Oregon, with exception of coastal towns.
Tuesday's final high is expected to be 97 degrees, easily outpacing the previous daily high record of 93 degrees set back in 1946. Expect hazy sunshine in spots with smoke from wildfires. A Red Flag Warning will begin at 11 a.m. for the Portland metro areas and central Willamette Valley, in order to prevent brush or wildfires.
Speaking of wildfires, there is no help weather-wise in fighting the blazes. Thus, an Air Quality Alert has been issued for a majority of central and eastern Oregon and Washington.
