Scenarios
Is it warm enough, or too cold?
One decision per page. Each one gives you the threshold, the variables that move it, and what to do on either side of it.
- Temperature to paint outside Ranges by paint type, plus the overnight low that ruins more jobs than the daytime high.
- Overwintering plants Per-plant thresholds, and the difference between chill damage and freeze damage.
- Too cold to walk the dog? Thresholds by size and coat, not one number — and the signs that mean turn back.
- Running in cold weather Layer for 20 degrees warmer than it is — and know where the real thresholds sit.
- Winter thermostat setting Three settings, not one, plus the floor that overrides every saving.
- When to cover plants The trigger temperature, what each material is worth, and the two mistakes to avoid.
- Cold weather and car batteries Two curves crossing, which is why failures cluster at a threshold.
- At what temperature frost forms Frost forms above freezing on clear still nights — which is why the warnings are not set at 32 °F.
- Temperature to pour concrete The pour is the easy part. The 48-hour curing window decides the outcome.
- When to turn the heating on A temperature trigger instead of a date — and what holding out actually costs.
- Halloween and Thanksgiving weather Normals for both dates across US regions — and how wide the real spread is.
- How cold is too cold for chickens They cope better than you think. Ventilation beats heat, and heat lamps are the hazard.
- Winter storm prep Ordered by deadline, not by category: what has to happen before the weather arrives.
- Scenarios Go or no-go answers for the jobs the temperature decides: painting, walking the dog, covering plants, pouring concrete, turning the heating on.
