I see you site is *currently* forecasting a mean wind of 32.1 mph for the
City of Derry for 0900 tomorrow - only 9 hours away. I'm amazed at your
resolution to 0.1mph, but have a feeling your error will be of the order

of
15-20 mph. I suppose you might have a .1 in the speed - well a 10% chance
- though no sensible forecaster would use such a resolution.


Mike,

I'm currently verifying forecasts/actual against last nights GFS for Derry,
you seem to have picked the one location which I am not sure whether the
data is correct for. A visitor yesterday complained that the forecast was
underestimating the actual wind speed so I had to do something about this to
verifiy the forecasts.

If the compaint is not upheld then the dataset will return to the original
configuration.... I'll email you when I know the results at 6pm tomorrow.

Yet you rubbish the GFS model in the above quoted paragraph - slight
contradiction?


Huh? The GFS is the mutts nutts with regards to emprical forecasts... it got
a day wrong, as Metcheck did... big deal... I was simply offering a balanced
view.
