Warmer weather forecast - but with some precipitation

The first signs of Spring are in the air as we move the clocks ahead tonight and the angle of the sun slowly increases. However we still have towering piles of snow around the city like this one in St. Laurent. It seems like it will take until July for them to melt away. (ValleyWX Photo)
After the stupid cold of this past week, it was great to reach the freezing point on Friday in Montreal. The overnight low at my home on L'Ile Perrot Friday morning was -21C but we manged to just nudge above 0C by late in the day. This was quite a big, but not uncommon temperature swing under the warm March sun. We had a little light snow overnight along a weak cold front, but that is coming to an end and we can expect sunshine the rest of the day and most of Sunday. Temperatures will remain around 0C today, dropping off to -14C tonight. By late in the day and overnight into Monday another weak clipper system from Alberta will bring 1-3cm of snow with continued milder weather. It will be near freezing during the day and about -10C at night. A couple of other small western systems will bring light rain or snow showers through Tuesday. By Wednesday, depending on which computer model you prefer, we may have sunshine or snow. A coastal system is expected to move up the eastern seaboard and could affect southern Quebec. It is too soon and with forecaster confidence rather low at this time, we will hold off on that threat and wait until we get through the weekend.
