These forecasts use interpolation to improve accuracy for your specific location, and are powered by either ECMWF or GFS model data depending on your selection. As with all weather forecasts, confidence decreases rapidly beyond 5 days ahead — treat the later dates as a heads-up about possible conditions rather than a firm prediction.

If you have a moment, please let us know what you think.
