Morning Planning Cues
- Prioritize forecast checks for spring and fall windows where overnight cooling and light winds align.
- Compare signal direction over several mornings instead of trusting one isolated model snapshot.
- Use the one-spot check as a quick filter, then sign in for saved alerts and multi-day planning context.
