“In its own league” – “Without precedent” These terms fail to convey how deviant of the Southwest US Heat has been. This visual shows the average temperature of each day in the Southwest US since 1979 (black). The average (green).
This year is the red line. The red dot represents last week’s peak heatwave day. I’ve been a meteorologist for 30 years and I’ve never seen a #heatwave of this size, intensity and longevity depart so far from the norm.
