I'm a bit surprised at the minimum temperatures forecast on BBC1 at 6.30
p.m. this evening. Single figure mins were predicted for Scotland but
elsewhere double figure mins were predicted. I haven't looked into it in
much detail but for this part of the country the McKenzie method
predicts a min of around 7-8C, assuming light winds and only small
amounts of cloud. This would be quite a bit colder than the TV forecast
suggested.

I have noticed for some time now that the forecast minimum temperatures
seem to err on the high side on radiation nights. I'm not certain but I
think that this apparent systematic error started at the time of the
introduction of the new graphics. It may be a presentation problem
rather than a forecasting problem.

I think the BEEB have dumbed down their mins, giving the likely temperature
when your average Joe Sixpack is leaving for work, rather that the actual
min.

This seemed coincide with the new graphics. You may notice that when they
show/talk about mins the screen says 8am or thereabouts.

I used to watch the BBC forecasts a couple of times a day. I'm down to a
couple of times a week now and think I'll stop soon.
