Arctic Air Mass To Shatter U.S. Early-Season Cold Records; Earth-Directed X-Flare To Deliver Double Hit; + BBC To Review Its Own Climate Lies

The last time the US saw this kind of early season cold was Nov 13, 1977. What followed was the historic winter of 1977-1978. (Image: 500 mb temps)

Arctic Air Mass To Shatter U.S. Early-Season Cold Records

A brutal Arctic outbreak is tightening its grip on the United States, with models showing one of the most severe early-season cold anomalies ever observed for November.

At 500 mb —the mid-troposphere level where large-scale air masses and jet stream dynamics are measured— the European model projects temperatures plunging below -40C (-40F) from the Great Lakes to Kentucky by Tuesday, November 11.

Such values are extraordinary for mid-November, rivaling events seen only a handful of times in recorded history. For example, the forecast of -38C (at 500 mb) near Dulles Airport Tuesday would break the November record of -37.3C set Nov. 13, 1977:


The anomaly forms a near-perfect, spherical cold core extending through the Midwest and Ohio Valley — effectively a dislodged lobe of the polar vortex swinging down from Hudson Bay:


At the surface, the cold will be just as historic.
