Sleepless in Seattle?

A high pressure system, to the North of Vancouver Island and British Columbia, is scheduled to bring record high temperatures to the Pacific North-West (https://www.theguardian.com/world/2021/jun/25/pacific-northwest-heatwave-washington-oregon). The Pacific NW is usually a relatively cool and damp place. The US National Weather Service reckon, however, that Oregon, Washington and Idaho could all surpass their all-time record temperatures (over 114 degrees Fahrenheit) at the end of June into July. Nights could be especially muggy in Seattle. There, only one third of households have air conditioning, as they don't usually need it! The breaking of weather records (both high and low) seems to be the shape of things to come in many areas of the globe. There was recently a tornado in the South of the Czech Republic in Europe. These things 'never' happen?
