Interpreting GFS data

[corvus17samaramail]

Hi, Patrick.


PR> I'd like to interprete the GFS data for a given time (like +18 h, for
PR> example) and put a pictograph telling whether it is sunny, raining,
PR> hail, cloudy, very cloudy, etc., starting from the precipitation data,
PR> the cloud cover, and any other available GFS data.

PR> I would appreciate any comment - even when you tell me that it is a secret !

Please contact me: corvuscorax at mail.ru



Best regards, Vladimir.
