ANALOG TRENDS:
This is not an official forecast, but shows you a blend of similar years & what commonality they have in terms of temperature & precipitation deviations from normal.
This shows what analog data suggested in the June outlook & in the latest outlook.
We've got an unusually cool to cold Atlantic, a very warm eastern Pacific, a developing El Nino Modoki with low solar output (lack of sunspots) with likely dominant eastward phase of the QBO..........all tends to point to colder & snowier than normal winter, but an overall below normal precipitation regime.
Analogs suggest warm December initially, then big change late month with consistent below normal temperatures January, February & March & considerable blocking by ridging south of Greenland & again over the Pacific Northwest & Alaska.
Analogs suggest cold perhaps like the 2013-14 & 2014-15 winters with many below zero nights here with snow deep into the southern U.S. & major snows on the East Coast. Meanwhile, unsually dry, mild to warm weather would give the Pacific Northwest a lack of gray weather (due issues with lack of rainfall),
It is odd that this analog package focuses more int he way of rainfall on California. Usually El Nino Modokis shift it a bit farther north.
