Icy overpasses and bridges yesterday morning and this morning have causednumerous accidents in and around Montreal. Slow down!
A rather unstable weather pattern is upon us, but it is zonal, west to east, so it should limit any big storms or really cold air. It will result in rapid changes in the weather over the next week. Skies will clear out this morning after some overnight flurries, just enough to make roads icy. Clouds will increase once again tonight in advance of two clipper systems this weekend. The first will bring a general light snow to the area overnight and into Saturday morning. I don't think much more than a centimetre or two will fall (perhaps 5cm in the Laurentians). Winds will turn out of the southwest and become gusty up to 50km/h causing blowing snow in open areas. We will see a few breaks in the clouds late Saturday before the next low moves in mid Sunday into Monday morning. This system will have a little more moisture and give perhaps 5cm locally to the area. It will be followed rapidly late Monday by a brief shot of cold air before a big warming trend late next week that will see temperatures go above freezing. Temperatures will be around -3C for highs this weekend and -10C overnight. Monday night lows could drop to -20C before the warming trend starts.
