On Thursday evening just gone, I checked the BBC 24 forecast for Sunderland
on Friday and it proclaimed it was going to be a day of unbroken sunshine
and no cloud cover at all. It wasn't an entirely unpleasant day, but there
was very little going in the way of sunshine and lots and lots of clouds.
Today, Saturday, the summary is still showing a big sun symbol for
Sunderland and a temperature of 21C. It's now 18.30, it's been cloudy all
day and started spitting rain at around 16.00... the temperature has been
quite cool and no where near the optimistic 21C.

The lesson seems to be that you take these 'forecast's with a pinch of salt
because all too often they appear to be wide of the mark.

Actually, the lesson I've learned is to take forecasts I *like* with a
pinch of salt, while you can bet the farm one ones you *don't like*
being correct.

Seriously though - high pressures seem far easier to predict than lows,
so once one of the former appears on an LRF, it rarely if ever fails to
materialise.
