Montreal's heavy precipitation event of 8--9 November 1996 was noteworthy for its all-time record-breaking 24-hour accumulation of 134.0 mm. We analyse this case through a study of the synoptic-scale and mesoscale states. / Searches for the best analogues to this event are conducted. Fields of the best mass analogue, for 1977, are compared to those of the 1996 event. / It is found that, in the Montreal area, the 1996 event had persistently larger precipitable water content and synoptic-scale ascent values. Averaging the storm-total precipitation values of five randomly-chosen Montreal-area stations yields a value of 74.8 mm for this event. The analogue case, despite its excellent synoptic-scale similarity, was characterised by an average value of only 20.2 mm.
