Short-range forecasting refers to predicting weather conditions for a time frame that includes the next few hours to a few days. This type of forecasting is often characterized by its reliance on current weather data and models that provide high resolution and detail over shorter periods. Meteorologists focus on immediate atmospheric conditions, which are subject to rapid changes, making it essential to have real-time data and observations.

In contrast, other options describe different forecasting periods: the first choice mentions a period of 1 to 3 days, which can overlap with short-range forecasts but does not fully capture the immediacy of "the next couple of hours." The second choice extends accuracy to about a week, which is more consistent with medium-range forecasting. Lastly, the third option implies forecasts that push beyond a month, aligning with long-range forecasting, which utilizes different methods and models than short-range forecasting. Thus, the definition that encompasses the immediate future to a few days best fits the concept of short-range forecasting.
