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!

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.
