Week of transition

It was a busy weekend as valleyweather moves from the south shore of Montreal to the just off the western tip of the Island of Montreal about 50km to the west. It will take a few days to get things properly up and running so the blog entries may be a little small.

This truly is a week of transition both personally and in the weather. The week will start off sunny and mild, although this "dirty" high pressure system continues to allow for low clouds and fog to form in the past 24 hours, this should burn off shortly. Temperatures continue well above normal for November, close to 8C. By Wednesday the first in a series of low pressure areas will begin to affect the region. Showers are expected from Wednesday into the US Thanksgiving holiday. By Thursday low pressure organizing along the Carolina coast will move north towards Long Island. Precipitation in the form of rain will spread inland from south to north across Vermont and New York and into Quebec and Ontario. At first rain is expected, but as cold air moves into the region from the north, we expect the rain to mix with and change to snow Friday night. It is very early in the forecast period, but be advised that colder weather and some snow is in the extended forecast. More on this later in the week.
