Additional
comments on the weather in November, 2005
[ The
bulk of these data are copied wholesale/adjusted from Clive Temperton's site
which is close-by: the break was due to our being in the process of selling the
house, but this was abandoned mid-November 2005, so I was able to restart observations
again. ]

marked squall-line 1525-1540Z, with wind up to F6, perhaps F7 for a short time;
