A towering cloud, especially one that appears tall and prominent, often indicates the presence of a cumulonimbus cloud, which is commonly associated with thunderstorms and severe weather. However, if it’s not raining in the area, it could mean the cloud is still in the development phase, or the precipitation is falling elsewhere. These clouds can form quickly and might bring rain later, or they could dissipate without producing significant rain.

To add your Personal Weather Station to Windy, you typically need to use a service like Weather Underground or Meteomatics, which can integrate with Windy. These services often have guidelines for connecting your PWS.
