We're thrilled to introduce Version 41 and guide you through its latest enhancements: Radar Nowcasting for a 1-hour forecast ahead of time, and two more aviation related features: Icing severity and Clear Air Turbulence.

Radar nowcasting

Our radar nowcasting feature allows users to see weather conditions up to one hour in advance, directly on the radar map. The process is calculated by optical flow, which is calculated over the whole composite at once through the process of extrapolation.

As this is a brand new feature on Windy, we'd like to hear feedback from your side. Let us know what you think in the comments. One of you can win a Windy sweatshirt!

Icing Severity

The icing severity feature offers automated, objective, and reliable forecasts of the probability of encountering icing conditions in different altitudes. This feature may prevent multiple aviation risks, such as the process of take-offs and landings or frozen precipitation on an aircraft. The layer is available in 5 different weather models (ECMWF, GFS, HRRR, NAM, ACCESS).

Remember to change the altitude, as the Icing Severity layer may change dramatically at different altitudes.

Clear Air Turbulence

Clear Air Turbulence (CAT), often viewed as a threat to aviation safety, makes it difficult for pilots and onboard radars to detect. It's a critical tool for planning air travel and understanding the broader climatic conditions. CAT also can to be interpreted in terms of altitude.

This layer is available in 9 weather models (ECMWF, GFS, ICON, ICON-EU, ICON-D2, UKV, HRRR, NAM, ACCESS)

Even more impressive with Windy Premium

We're delighted to enhance your Windy experience by making it more seamless and adding new relevant features. Icing Severity and Clear Air Turbulence layers are available in a 10-day forecast (ECWMF and GFS model) with Windy Premium.
