First a few words about my forecast for Easter issued on Friday 02/04/04.
It was probably the worst forecast I have ever prepared since starting
these
weekly discussions. At the time of issue most forecast models and ensemble
data
had been going solidly for a cold northerly plunge with only a hint at the
time
that things may not turn out that way. On the next day - Saturday that
hint
became stronger but then it was too late of course. Also first principle
forecasting gave a northerly plunge over the UK with strong warm advection
of
air to the west of Greenland, in the event this did not come to pass and
so the
plunge of cold air went to the east. Having said that most people weren't
too
bothered, with the weather turning out to be much more pleasant than I
predicted. In retrospect perhaps my confidence level should have been
moderated
given the few hints that it may not come off at time of issue.
I for one was quite happy with the weather as it happened in Edinburgh for
my easter break, so don't beat yourself for it going awry.
