{
  "id": "MLC-T-MET-005713",
  "term": "Forecast lead time",
  "field": "Meteorology and atmospheric science",
  "definition": "The duration between the time a weather forecast is issued and the future time for which the forecast is valid. For example, a forecast issued at 6 AM for conditions at 6 PM on the same day has a 12-hour lead time. Longer lead times generally correspond to lower forecast accuracy due to the inherent chaotic nature of the atmosphere.",
