Twelve hours without a long scroll
Weather Slate’s Next 12 Hours design uses two rows of six forecast cells. Time, a weather icon, temperature, and precipitation probability when useful sit together. A “Now” indication makes the current hour easier to find.
Read across the hours in sequence. First look for a change in conditions, then compare temperature and rain probability around that change. The small cells are a way to orient yourself; they do not replace the detailed daily outlook.
- Next hourWhat may happen soon?
- Next 12 hoursWhen does the day change?
- Next 10 daysWhat pattern should I prepare for?
Timing can change the whole decision
A forecast with rain late in the day may still leave a useful morning window. Conversely, an afternoon high can hide a chilly start. When you compare times, include the trip there, the activity itself, and the journey home.
For example, an errand that takes 20 minutes is a different planning problem from a two-hour practice at the same start time. Review the entire window instead of selecting a single favorable hour.
What an hourly rain percentage means
A precipitation probability describes the chance of measurable precipitation at a point during a specified period. It does not describe how much of that hour it will rain or how heavy it will be. See the National Weather Service forecast terms.
Hourly probabilities can change as the expected location and timing of rain change. Do not add percentages from adjacent hours or average them to calculate a daily chance; those periods are related, and the daily product covers a different interval.
Use the right view as your departure gets closer
The hourly forecast is useful for choosing a window. Close to departure, check 60-minute precipitation and radar for more immediate context. Recheck if your plan moves to another time or location.
Forecast hours are estimates, not appointments for the weather. Leave some flexibility around transitions, especially when showers are scattered. A dry-looking cell does not cancel an official warning.
