I've gone back to my thickness study I stuck on here last month -
top 10
lowest thicknesses I could find from the NCEP reanalysis (which I
realise
will have its errors, and I've only looked from 1960-2000) is - and
these
are daily mean thickness for a gridpoint in west/central England:

Date TT500
22/11/1965 517.2
19/11/1971 519.2
19/11/1962 519.4
21/11/1993 519.4
29/11/1969 519.7
23/11/1993 520.7
28/11/1985 520.8
22/11/1993 520.8
28/11/1980 521.2
25/11/1978 521.3

.... interesting, thanks Richard: *if* the GFS output is correct (still
indicating sub-512 dam), then we'll be testing all of those values
come this weekend!
