Stratospheric Warming Caused The Historic U.S. Arctic Outbreak

A stratospheric warming event occurring Dec. 21-25 across northern Canada caused an arctic air mass to emerge in southern Canada touching the northern U.S. Dec. 24-28. The southern periphery of the arctic cold gained snow cover in the following days with resurgent following arctic air growing more intense as the polar vortex intensified and snow cover widened/deepened. The result for early January in the Midwest/East U.S. was a record to near record cold for the first 6-7 days of the New Year.

Sydney, Australia 117F! Why?

Sydney, Australia roared to 117F over-the-weekend, the hottest day in 80 years. Foreshadowing this event is the super warm ocean surface east of Australia. More super heat for eastern Australia is likely for summer 2017-18!

Bombogenisis Off NE Coast Tomorrow!

The arctic air reservoir across the Midwest/Northeast U.S. this afternoon is set to be replenished over the next 2 days pulled southward by a developing storm off the Mid-Atlantic/Northeast coast. The developing storm will be quickly unusually intense due to the replenishing arctic chill across western North Atlantic SSTA averaging 1-3C warmer than normal.
