Wow, how quickly the weather and seasons can change. With fall just a week away, cold air is pouring into the northern plains and Prairies. It is -5C this morning in Regina and 0C in Winnipeg, both were in the 30's just last week. Montreal managed to reach 27C yesterday before a turbulent cold front raced across the region. Thunderstorms lasting several hours, produced heavy rain, over 25mm in many locations.
Today southern Quebec will see variable skies with temperatures nudging to the 21C mark. Another cold front will bring showers tonight and a re-enforcing shot of cold air that will see temperatures drop to cold lows around 5C by Friday morning and daytime highs only around 15C.
Tropical Storm Maria is south of Bermuda this morning and expected to pass west of the island on Thursday before accelerating northeast. The storm is forecast to come close to Nova Scotia and possibly cross the Avalon Peninsula in Newfoundland by the weekend. Heavy rain, strong surf and gusty winds can be expected from Maria in southern coastal Nova Scotia and especially southern and eastern Newfoundland. Currently the storm has 60mph winds with some strengthening expected over the next 24 hours.
