USA · NOAA / NCEPGlobal Forecast System: a numerical model that simulates atmospheric physics.
Ensemble charts show a range of scenarios. Different charts may use different issue times, variables or reference elevations. The local forecast for 380 m is on the Forecast page.
Global Forecast System: a numerical model that simulates atmospheric physics.
Artificial Intelligence Global Forecast System: a machine-learning model initialized from NOAA atmospheric analyses.
Integrated Forecasting System: the intergovernmental European centre’s numerical model. IFS 9 km and IFS 0.25° are products of the same model family on different data grids.
Artificial Intelligence Forecasting System: this page uses AIFS Single, which produces one forecast scenario.
Global Environmental Multiscale: the atmospheric model within Canada’s GDPS. The current system combines numerical prediction with large-scale guidance from the GEML AI model.
The blend uses the values available for each day and variable. Coverage falls as individual models reach their forecast limits. The two IFS products are not independent models. Model spread shows disagreement, not the probability of a weather event.
Wind: maximum daily speed at 10 m and prevailing direction of origin. Direction uses a speed-weighted circular calculation; missing or strongly opposing directions display a dash. 🥶: low below 0°C. 🥵: high above 30°C. 💨 in Conditions: wind at least 40 km/h or gusts at least 60 km/h.
