Are long range climate forecast maps (on the Internet and from other sources) useful for pin-pointing city specific forecasts?
Seasonal climate forecast maps, available for the U.S. and the world, are usually qualitative, indicating which areas are more likely to be warmer/colder, or wetter/drier than normal. The key word here is likely. These forecasts do not indicate the magnitude, or amount, of warmth or cool, only the increased chance an area will be warmer or cooler. Such seasonal forecasts, including analog and climatology forecasts, are adequate for broad-brushing trends, but they do little to forecast specific weather outcomes for specific cities and weather stations.
