A disturbance across the Great Lakes will track east-southeast through tonight (Monday night) and spread thunderstorms from Michigan into southern Ontario from late this afternoon into tonight.
The greatest threat with these storms will be strong, straight-line winds and heavy downpours.
Strong thunderstorms capable of producing strong winds and hail will also track across southeastern Alberta and extreme southern Saskatchewan this afternoon and through the evening.
By Wednesday, a stronger system will produce more widespread showers and thunderstorms from southern Ontario through Quebec. At this point, I see the greatest potential for damaging thunderstorms from near Hamilton, Ontario, through Kingston, Ontario, and up into the Montreal, Quebec, area.
The new ECMWF forecast model monthlies (through the end of the year) are out, and I will discuss them on my next post.
