This website is automatically updated in near real time (approximately every 3 minutes) with weather observations from a WeatherFlow Tempest personal weather station located in Dunstable, Bedfordshire. Weather data is received by the Tempest Hub via UDP broadcast on the local network, and processed by WeeWX running on a Raspberry Pi.
The station has been recording weather data since 2020 and provides continuous observations including temperature, humidity, pressure, wind, rainfall, UV, solar radiation, lightning detection and cloud base estimation.
Many thanks to Manfred Kirchner (wetter-ruppersthal.at) for providing the files for the climatological history charts.
TorCast AI is a locally-developed UK severe weather prediction system running on-site. It produces probabilistic forecasts for thunderstorm, severe weather, hail and tornado risk across 440 UK grid points at 0.33° resolution.
The system ingests data from four deterministic NWP models (ECMWF IFS, GFS, ICON, ARPEGE) and three ensemble suites (ECMWF-ENS 50-member, GEFS 31-member, ICON-EPS 40-member), extracts ~48 convective features per grid point, and runs a trained XGBoost/GradientBoosting classifier to produce calibrated risk probabilities.
Training data is sourced from ESWD and TORRO verified storm reports combined with ERA5 reanalysis vectors. Post-processing applies CIN-aware hard caps to prevent physically implausible outputs on stable days.
The model is retrained after every 5+ new verified storm events and verified against ERA5 using Brier Skill Scores.
