A relative difficult method of forecast, the analog technique requires remembering a previous weather event which is expected to be mimicked by an upcoming event.  What makes it a difficult technique is that there is rarely a perfect analog for an event of the future.<ref>[http://ww2010.atmos.uiuc.edu/(Gh)/guides/mtr/fcst/mth/oth.rxml Other Forecasting Methods:  climatology, analogue and numerical weather prediction.] {{Webarchive|url=https://web.archive.org/web/20070519200402/http://ww2010.atmos.uiuc.edu/(Gh)/guides/mtr/fcst/mth/oth.rxml |date=2007-05-19 }} Retrieved on 16 February 2006.</ref>  Some refer to this type of forecasting as pattern recognition, which remains a useful method of estimating rainfall over data voids such as oceans using knowledge of how satellite imagery relates to precipitation rates over land,<ref>Kenneth C.

A variation of this theme, used for medium range forecasting, is known as [[teleconnection]]s, when systems in other locations are used to help determine the location of a system within the regime surrounding.<ref>Weather Associates, Inc.
