The Weather Network provides radar-based six hour nowcasts on their web site, based on extrapolation of radar imagery. The aim is to evaluate and improve the performance of these forecasts which use a version of MAPLE (the McGill Algorithm for Prediction by Lagrangian Extrapolation). One goal in Phase I has been to see over what lead time, under various circumstances, nowcasting procedures give reliable results. In Phase I we are focusing on the southern Ontario region where lake effects can strongly influence winter snowfall.

天气网根据雷达图像外推法，在其网站上提供基于雷达的6小时临近预报。其目的是评估和提高这些预测的性能，使用MAPLE（麦吉尔算法预测拉格朗日外推）的一个版本。第一阶段的一个目标是，在不同的情况下，看看在什么样的提前期内，临近预报程序给出了可靠的结果。在第一阶段，我们将重点放在安大略南部地区，那里的湖泊效应会强烈影响冬季降雪。
