Forecasted Temperature variations
-
In the coming days my area is expecting sub zero temperatures. My preparation from experience is more drastic below -10C. Weather com forecasts-8, environment Canada -7, AccuWeather-10, the weather network-6. Windy is forecasting-15C. Why would there be such a significant spread?
Cheers

What weather model do you use in Windy and where exactly?
Windy's default model has a resolution of 9 km, and if you're in the BC mountains, it can "see" your location at a higher altitude. But in Windy, there are several weather models, including a Canadian model, that can probably provide better temperature forecasts for your location. -

Thank you.
The banks of the Fraser river are surrounded by high mountains. So global models like the ECMWF and GFS with a medium resolution cannot provide correct temperature prediction.
As a Premium user you can use the Observation vs forecast tool to find the best model for temperature.
Here I selected a weather station near Agassiz. In the red rectangle you see the median temperature error by models.
The regional models like HRDPS, HRRR, NAM are a bit better but the best is definitively METEOBLUE.
This model is only available in the local forecast table, not as a map, but provides right temperature forecasts in mountainous areas.
If you need further explanation just let me know.
