An animation of the Heat Dome #HeatDome presently over the United States which is responsible for the heat wave. The dome appears to be pretty stationary and covering the entire U.S. land mass. /1
The animation shows a period from today till July 23 (a bit over a fortnight). And as you can see this Heat Dome is not forecast to depart. Below are images from the beginning and the end of the sequence. Today on the left, July 23 on the right. /2 
The darkest red contour line shows the height of the atmosphere as 597 dm (decameters) or 59.7kms. The lighter dark red shows 59.4kms. The higher the atmosphere the higher the average air pressure on the ground. /3
NZ was one of the only populated places on the planet yesterday where there were temperatures under 15 degrees celsius.
This shit is not normal. (HT @cupoteacoast)
