"Here we are in the graze of winter"
John Mellencamp
the time was October 31 1991:
Winter's moved in, what they call an "Arctic blast", changed the configuration of the entire North American weather map. Very bitter cold. This in part created the Perfect Storm of Andrea Gale fame, ode to the fishermen of NE coast who braved it.
2016 has same winter blast, much weaker, is a coming 40 days late:
ECMWF portrays coming High pressure "Arctic dome" originating mainly from Alaska,
a pale shadow of former self, while the Arctic Ocean is currently dominated by a Cyclone which just kicked out a budding mega cold "dome" forming, the by-continental merge of cold air zones was cut in two, leaving Alaskan build up to come down the Rockies path. However, on the East coast of North America, a huge Cyclone system will blossom December 9-10 not unlike segments of the Perfect Storm of 91, but minus Hurricane Merge, December being well past hurricane season, the last one Nicole streamed by Mid-October 2016.
Last 30 days (from December 7) NOAA temperature anomaly. North America is not as cold as old November's use to be.
We have an "Alaskan Cold Dome" slowly moving South, looking very similar to the 1991 chart above, 40 days late from the Perfect storm date. Winter is starting late. CMC 0600 UTC 12/08/2016. WD December 8, 2016.
