The first snowflakes of the season possible by late Halloween night....very scary!

There could be snow on the pumpkins of southern Quebec by Saturday morning.

 The first snowflakes of the season for Montreal and the St. Lawrence Valley may be in the air as early as Halloween night or Saturday morning. Low pressure is forecast to develop from a rather complex weather setup with a cold rain late Friday in the region and perhaps ending as a period of snow. The system will evolve along the east coast which means areas of the Townships and Eastern Vermont have the greatest threat for accumulating snow. The coldest air of the fall will be drawn down behind the system. Temperatures will be mild most of this week but drop on Friday down to the freezing point by late in the evening, even here in metro Montreal. Overnight lows into Saturday morning will be down to -3C, so anything that does fall from the sky will be snow. I am hopeful we will make through the Trick or Treat period dry but cool.

We will have to monitor the systems development as the week moves along. Temperatures will only be 5C (41F) for a high on Halloween Friday with the low temperature dropping into the minus 3C (26F) range by Saturday morning. Frost or a hard freeze is likely this weekend everywhere. In any event the last week of October is always the time I head over to Gordons in N.D.G. to get the winter tires on and this year is no different. Time to put your winter preparations into to full gear, once we are on the other side of Halloween, we are at the mercy of the seasons.

Our clocks go back one hour this Sunday at 2am, another sure sign of winter!
