frost window
Turns an hourly forecast into the thing that is actually planned around: continuous frost windows. Each window carries its start and end hour, its duration, the lowest temperature within it and the hour that low occurs, so a two-hour dip at dawn is distinguishable from a night-long freeze. Air frost and ground frost are reported against separate thresholds and never conflated: forecasts are for two metres above ground, and on clear calm nights the surface runs three to five degrees colder,.
