Castle Rock Area Outlook
While the Castle Rock area is not part of the watch, our area bears close watching as heavy and slow moving thunderstorms could impact the area in the afternoon and evening hours. A large blob of monsoon moisture has increased dewpoints and precipitable water values across the area, this means any storms that form will have a large amount of moisture to work with and fall as rain.
What to watch for this afternoon:
- Slow moving thunderstorms with heavy rain may cause localized street flooding
- Frequent and dangerous cloud to ground lightning
- There is a small chance of hail with some of the strong storms
