Storm Begins June 8-9, Report on Global Specific Humidity

By Paul Huntington Starting on June 8 Thursday a big pattern change is taking place with a very unseasonable strong low pressure rotating down from Aleutians and could bring as much as a foot of snow above 8000 ft, adding even more white stuff to our already incredibly large snow pack in the Sierra. The meridional angle (El Nino type trajectory) of the jet stream in the North Pacific is following a very similar path to what brought us saturated air masses throughout the Winter in 2016-2017. Moreover, it seems the Arctic Oscillation is finding a quasi equilibrium more around negative than positive meaning the pressure gradient in the North Pacific on the southerly extent of the northern hemispheric jet stream (westerlies) is lower than average thus allowing the jet stream to dip down into California. Also the Antarctica Oscillation is finding a quasi equilibrium in the positive (climate change and a warming planet could be fueling this pattern change) meaning the jet stream is hugging...
