I know Philip Eden has already mentioned it, but why and what has
caused the the Greenland High to be so dominant over the past 3
months?

If only this was Winter, we may be in for some interesting cold
weather.

However in Summer it is just a spoiler.

If this continues, people may stop talking about global warming and
start talking about localised cooling!

If only anyone actually knew! And; if only anyone could have actually
predicted its persistence and be confident of doing it again in the
future!! Weather life would then be a much more forecastable
place.....though perhaps much more boring too!

With the Low ancillary n the North American side whilst we have a
local low and a nearer Scandinavian one, snow is unlikely fopr us
whilst Ice Storms or their summer solstice equivalents are likely for
N. America.

History of snowflake studies. Rough sketches of snowflakes were
published by Olaus Magnus of Uppsala around 1550. Johannes Kepler made
more detailed pictures and identified hexagonal symmetry around 1611.

Over the course of the next few centuries, following work by René
Descartes, Robert Hooke and others, progressively more accurate
pictures were made and correlations between weather conditions and
snowflake forms were found.

Thousands of photographs of snowflakes were taken by Wilson Bentley
over the period 1884-1931. Beginning in 1932 an extensive study of
snowflakes was made by Ukichiro Nakaya, who in 1936 also produced the
first artificial snowflakes. Most of the fairly small amount of more
recent work on snowflakes has been done as part of more general
studies on dendritic crystal growth.

Note that tree-like snowflakes are what make snow fluffy, while simple
hexagons make it denser and more slippery. The proportion of different
types of snowflakes is important in understanding phenomena such as
avalanches.

Might help explain the slushy stuff we are prone to.

Forgot to mention the obvious:
While an adjacent Low and High to our north will provide a south
flowing air mass (Winter's cold north winds) two Lows to our north
will just make a mess.

The cylone on the one side will have winds flowing opposite the way
the cyclone on the other side is flowing.

Strangely it might explain how it is that Highs and Lows don't cancel
each other out. At least it indicates that twin cyclones or for that
matter twin anticyclones will never form a perfect storm.
As for the Perfect Storm:

PHAH!
