Cloud conditions can change quickly and vary locally, so using multiple weather sources is key to accurate planning. Here’s how to do it:

  • Check weather apps: Use Clear Outside or Windy for detailed cloud layer forecasts.
  • Watch live webcams: Local sky cams show real-time cloud coverage and movement.
  • Review satellite imagery: Infrared maps reveal cloud thickness and altitude on a broader scale.
  • Consult local METAR reports: These aviation weather reports provide cloud base altitudes and visibility.
  • Observe the sky yourself: Nothing beats your own eyes for spotting subtle cloud changes.

By cross-referencing these sources, you reduce surprises and increase your chances of shooting under ideal conditions.
