Key Messages
- A mild, largely-dry Halloween is in store with intermittent sprinkles/light rain being the only sensible weather.
- A more potent system arrives late Monday and brings the likelihood of a widespread, beneficial rainfall through at least Thursday. Hazardous weather associated with this system is very unlikely (less than 10%).
- Temperatures begin a gradual cooling trend today, but remain at least near early November normals.
