About this forecast

The outlook for the next few days comes from computer weather models and is refreshed regularly. The first two or three days are the most dependable. Beyond that, the exact timing and strength of rain and wind becomes less certain, so treat later days as a likely pattern rather than a promise.

For hour-by-hour detail see the 48 Hour Outlook page, and for how closely different forecasts agree, see the Forecast Comparison page.
