Obviously nothing's perfect, but I'm mostly impressed with how close modern forecasting is .... the longer the lead time the more it's likely to change .... but by the time it gets to tomorrow's weather they're usually pretty right (even when it seems unlikely ... recently we were having a real run of great weather and the forecast suddenly said snow tomorrow ... you'd never have thought the weather could change so much so quickly .... but against all expectations, snow it did!)
Not what you want to hear Graham .... but who knows? .... could be one of their off days and you bask in sunshine with the hood down ...hope so!
