Easter snow for Montreal

Special Weather Statement for snow for southern Quebec.
Winter Weather Advisory for snow: Adirondacks, Northeast Vermont.

The seasons will do battle this weekend as is typical in the volatile season of spring. There is plenty of energy available in the atmosphere from April through June, that is why we have so much severe weather in the central and southern plains of the US. Cold air remains in control of portions of central and far northern Canada while warm and humid air has started streaming northward form the Gulf of Mexico. This scenario will be all too clear in Montreal over the next 24 hours. We start this morning very mild at plus 6C (43F) with the prospect of our warmest day since early November. With some sunshine through thickening clouds we may reach 14C (56F) in Montreal and Ottawa.

A strong cold front will move across the region late this evening stalling to our south separating the warm air from unseasonably cold air that will become our reality for this weekend. The temperature will crash from today's warm highs down to -3C (27F) overnight. Low pressure will develop and move along the front with rain developing this evening and changing to snow overnight in Montreal. Wet snow is likely Saturday with a cold high of only 2C (36F). The heaviest snow will fall south and east of Montreal with 10-15cm in Sherbrooke and northeast Vermont. From Montreal east to Quebec City we can expect 5-10cm with 2-4cm for the Ottawa Valley and eastern Ontario. The snow will taper off Saturday but it will be a raw and chilly day. Temperatures will be cold Saturday night with lows of -7C (19F). Easter Sunday will be partly sunny and cold with a high of only 2C (36F).

Looking ahead to next week, it remains unsettled and cold for early April with the chance for more snow. The good news is we see some above normal temperatures finally by the middle of this month so don`t loose hope.
