Answer: analog method
Explanation: Analog method of weather forecast takes a look at today's forecast and compares it with a day in the past when there was a similar weather forecast or situation, it would be predicted that the weather will be similar to how it was in the past. It is a complicated method of weather forecast because it can be difficult if not impossible to get a perfect analog, weather situations rarely align in the same location when compared with the way it was in the past.
