|It turned out to be a decent Sunday with the sun and clouds playing in a gusty northwest wind. The fall colours were in fine form across the St. Lawrence Valley including Lancaster, Ontario yesterday. (ValleyWX)|
Our weather for the start of this week will be controlled by a very strong early fall storm located in Hudson Bay. This storm is producing a wide area of snow and very strong winds across portions of Nunavut and northern Manitoba. Its effects on southern Ontario and Quebec will be in the form a persistent northwest flow of cool, moist air with a couple of areas of clouds and showers rotating throughout southern Quebec into Wednesday. In between the cloudy periods and showers we may see a few glimpses of sun like this morning. Temperatures will be seasonable today at 16C (60F) but rather mild on Tuesday and Wednesday, close to 19C (66F). By Wednesday a more important area of showers will lift northwest off the Atlantic across New England and into Quebec with perhaps a decent area of rain. More on that tomorrow. We will not see clearing skies before Thursday, and it will turn cooler and dry for next weekend.
