You need to learn to read the synoptic charts and learn local weather patterns.

In some situations the weather is very predictable for 3 to 5 days and the reliability of a forecast nears 100%

In others say where you have strong instability, sea temps above 83 degrees and weak pressure gradients the weather is very unpredictable even for 12 hours.

I learned my weather lore flying hang gliders and the book I relied on was written by Chapman [ I think - it was a while ago ]
