From the National Weather Service Operations Manual, the Probability of Precipitation (POP) forecast is "The likelihood of occurrence (expressed as a percent) of a precipitation event at any given point in the forecast area. The time period to which the POP applies must be clearly stated (or unambiguously inferred from the forecast wording) since, without this, a numerical POP value is meaningless." (

So if the POP forecast for Laconia is 30%, then there is a 30% chance that Laconia will see precipitation.
