We are looking forward to receiving feedback on the usefulness of the longer period forecasts, we aren't sure how good they will be. We suspect that different users, who each have their own particular need for a forecast, will each have a different perception of their usefulness and accuracy.
Clearly reliability will decline with the length of the forecast - experience and time will tell how significant this is. We wouldn't advise anyone to take the seven day forecasts literally but hope that these longer forecasts will provide some useful indication of how things might develop.
If the longer forecasts are of little or no value then we will remove them from the MetVUW site.
