Last year I developed a method of estimating snowfall from
looking at the daily Central England Temperature and England
Wales precipitation series. I thought it made a fairly good stab at
producing a Central England Snowfall series and one of the
weather events it highlighted was the bitterly cold period in
January 1987. I thought then I would blog in more detail about
what I remembered - It’s hard to believe that all happened 27
years ago!

My estimate using that method was for 7.1 cm of snow for the 11
January 1987 making it the 21st snowiest day in Central England
since 1931, but that was way of the mark for Louth in Lincolnshire
where we lived at the time, and I can still remember quite clearly
over 30 cm of the lightest powder snow accumulating during
Sunday the 11th.

I suspect that the low temperatures made the snowfall unusually dry and
powdery, such that a modest amount of precipitation (once melted)
equated to an awful lot of snow. Also I think Louth is fairly near the
east coast, isn't it, which may have meant that it had more snowfall
than places in Central England that are farther west.

Thanks for a fascinating analysis.
