ROANOKE, Va. – In recent weeks, the heat has broken records in parts of the Western United States; however, it’s now the Pacific Northwest that’s getting in on a potentially historic heat wave. This is especially dangerous, as this is a part of the country where proper air conditioning is lacking.
Excessive Heat Watches and Warnings are in effect for the coming weekend into early next week for several parts of northern California, Oregon, Washington and Idaho.
An extremely strong area of high pressure will be camped out near Washington and British Columbia. The stronger the high pressure is, the more the air sinks and heats up.
This is why places like Portland, Oregon could break an all-time record high temperature on Sunday.
Extreme heat wave expected this weekend, likely breaking several records. Make sure you're prepared for the heat!— NWS Portland (@NWSPortland) June 23, 2021

Seattle’s records go back to 1945. In that time, the high temperature has hit 100° twice - once in 1994 and one other time in 2009. In fact, its average high temperature this time of year is in the 70s.
This kind of heat is more characteristic of late June in Las Vegas.
This also is bad news for areas already impacted by an extreme drought.
The National Weather Service in Seattle is warning of heat-related complications, but also warning that water temperatures in area rivers are still in the 50s and 60s.
This will be a significant heat event for the Pacific Northwest. Hot temperatures will lead to heat-complications if preventative actions are not taken. We’ve highlighted some calls to action to prepare for this record shattering heat event. (8/8) #WAwx pic.twitter.com/FQgWelLndK— NWS Seattle (@NWSSeattle) June 23, 2021
