WXSim Forecast Page

Our hyperlocal forecast combines multiple realtime and modelled weather data, ROAB (upper-air) soundings, synoptic and local observations using an application called WXSim to simulate and model weather systems and the likely surface conditions up to seven days ahead. The forecast is generated seven times a day, every three hours from 03:00 until 21:00. There is no forecast issued at 00:00. Due to data availibility, forecasts for three and more days ahead are more accurate when issued after 12:00.

Feeding into the main forecast algorithms is a second application that uses machine learning to create bias corrections to ECMWF data modelled using current and historical observations from our local station. These correction data improve the overall forecast accuracy as much as 20% to 30%.

The forecast is presented in the European Weather Network format. The top section shows the issue time, next update and the forecast for the coming hour, with unit options on the top right. A six-day iconic forecast follows, with three tabs below: Overview (detailed day and night forecasts), Table (hourly conditions, selectable by day), and Graphs (visual forecasts for each day or the full period). See the About page for more information.

Visit the WXSim Website for more information on the application and its development.
