Potential storm to pass south and east of Montreal

The stalls were full and customer traffic was steady all day Wednesday at Gordons in N.D.G. The annual rush to get snow tires on and have the car tuned before the snow flies is well underway. Customers were lined up before the 7am opening on Wednesday morning and it will be the same for the next month. (ValleyWX Photo)

It looks like our first shot at snow for the 2014-2015 season will just miss Montreal. A cold upper level low will dive south from the Great Lakes into the Ohio Valley on Friday before moving off the middle Atlantic coast Saturday. This system will then develop into a strong Nor'Easter and move towards Atlantic Canada by Sunday. The path of the low will keep it well offshore, far enough to spare Montreal from any significant weather. However, if you have friends or family in interior New Brunswick, they may see a decent snowstorm on Saturday night with rain changing to wet snow. The same is possible across eastern interior New England depending on the track of the low.

At this time the weather looks grey and cool in Montreal with perhaps a stray shower for trick or treating on Halloween night. Temperatures will be around 5C (41F), so dress the ghosts and goblins up well. Until then expect mostly cloudy skies, typical October weather, with a cool gusty wind. The high temperature today will be near 8C (47F). The weekend forecast will feature clouds on Saturday with a cold north wind gusting to 40km/h and perhaps a few showers or a stray snowflake in the mountains, highs only near 5C (41F). Sunday will be partly sunny and cold with highs near 4C (39F). Overnight lows this weekend will range from 0 to -3C (26-32F), so frost and a freeze will occur.
