Never mind the medium range, today's forecasts in BBC R4 have been
pretty useless. Unless my hearing is faulty, the only mention of rain
on the 7.55 forecast was some drizzle over Wales. There was already
some precipitation in the SE showing on the radar then, and here we
had intrermittent slight drizzle all night, and this developed into
over an hour of moderate rain and drizzle here, and appeared to be
quite widespread on the radar. The models obviously missed this
development, and a lack of a decent covering of 'real' obs and a
dearth of radio soundings makes this type blunder only to be expected..
I noticed too, that the EGLL TAF has almost as many amends as there
were METARS!. On the 1255 forecast I heard a lot about how cold it
would be later in the week, but no mention or apology for the
downright duff forecasts for today.

The forecast for SE England currently shown on the Met Office website,
and time-stamped at 13:19 says:

This Evening and Tonight:
Often overcast skies tonight with mist and patches of fog. Light winds
at first will freshen later. It should be a dry night for most, but with
a few spots of drizzle in the wind. Minimum Temperature 5 °C.

I happened to be visiting a friend in SE London today, and there was
moderate rain there from at least 18:30 to 19:00. So it seems that
nobody at the Met Office noticed that their forecast was wrong till
later than 13:19, and even then they didn't bother to issue an updated
forecast. I know it's Sunday, and perhaps there aren't mainly people on
duty, but it's not very impressive.


TBH I don't think many care anymore. Morale is still rock-bottom and I
know of several who want to give up operational meteorology as the plan
is still full automation (apart from warnings) by 2020.

Another point is that there is now no experience left in UKMO. I mean
real experience of 30 years+ in synoptic met. relating weather to charts
etc. If the model says no then the forecasters have little to draw upon
to go against it. An example is showers. Not many people know that the
high res models do not advect showers, they are formed in situ at each
gridpoint. That is why windward coasts get warnings and not places
downwind. Of course if the forecasters had a lot of experience of
different situations then they could correct that. The next 10 years may
see very poor forecasting indeed until models improve and start to take
over the experience of relating weather to synoptics. But then again the
scientists to do this automation work are often not experienced either,
oh dear! And no I'm not going back, I love not working after getting
voluntary redundancy (and a big pay off) in 2012.


Oh dear, more smugness. Look at me, see how much I've been paid off at the taxpayers expense. Best not mention that gilt-edged pension, eh?
