Tienen - east of Brussels - reported about 1 cm snow on Monday.

Tienen is well-known for its large sugar factory. The effect of the extra
water vapour released into the atmosphere by the factory and the prevailing
freezing fog led to the snowfall. A similar phenomenon occurred in places
in Germany.

Seen this several times in or near Didcot, Oxon. From the cooling towers
of the power station. In fact I've seen it this winter during the cold
spell at the end of November.

Usually it is a very fine deposit of ice crystals. The most I've seen is
around 0.5cm in a very clear "stripe" heading SE from the power station
about 15 years ago.

The more annoying weather phenomenon around Didcot is the Didcot gloom
when you are situated right underneath the plume on a summer's day and
register no sun, whereas a few hundred yards in either direction it is a
glorious.
