Enjoy the colors quickly, with strong winds forecast this weekend, lots of leaves will be hitting the ground.9:45am UPDATE: Heavy Rain Warnings have been extended to Montreal and the metro region for up to 100mm of rain over the next 24 hours. The heavy rain will cause ponding of water on roads and highways as well as some flooding. Watch for blocked drains and sewers due to leaves.
Low pressure is developing this morning in Ohio and is expected to deepen rapidly and move into Ontario over the weekend. This system will bring strong winds to the region along with showers. This morning we remain under the influence of a low pressure trough swinging through the area. Bands of heavy showers and embedded thunderstorms continue to move form south to north from New York into southern Quebec. The rain could be heavy at times with 30-50mm quite likely over the next 24-36 hours. Temperatures will be mild today but gradually cool over the weekend. As the system moves to our north, strong west and southwest winds will develop tonight and last into Saturday. Winds will gust between 40-60km/h in Montreal and locally as high as 80km/h in parts of Ontario and Quebec. Warnings and advisories may be needed for Saturday. Very little sunshine is expected this weekend.
On the backside of this windy system, it will turn sharply colder with rain turning to wet snow in northern Ontario, with as much as 10cm forecast for Pickle Lake and Big Trout Lake.
