Measurements taken from house allowed NASA to create a heatmap of the northwest, exhibiting the gulf between this weekend’s temperatures and the common temperature for the time of 12 months. Utilizing information from the Goddard Earth Observing System (GEOS) mannequin of air temperatures about 6.5 ft above the bottom, the map is blue in areas the place it was colder on Could 15 than that date’s common, and pink the place it was hotter. The darkest pink zones are the place air temperatures have been greater than 12 levels Celcius (22 levels Fahrenheit) above common.
