Our computer model ?Extended GFS? goes out 14 days and can be used as a guide for trends.
Our ?Rain Dates Forecast? goes out 28 days and is updated every 14 days. This suggests dates of likely rain (for rainfall >=1mm from 9am of the date to 9am the following day).
Dates which are covered by the 1st 7 days are dates where rainfall >=0mm is likely.
(Both the Extended GFS and Rain dates forecast require Weatherzone Pro subscription access).
