Weekend Update

Another sunny day is expected in southern Quebec and eastern Ontario today as high pressure prevails. Yesterday we reached 30C and it should get very close to that again today. So far the showers and thunderstorms have remained to our southwest over western New York and Ohio. I believe they will stay there. A weak cold front will cross the region tonight with clouds and a slight risk of showers. The weekend looks great at this point with sunny skies both days and seasonable temperatures around 25C.


Alberta funnel clouds
A big spin of low pressure in the upper atmosphere produced numerous heavy showers and thunderstorms yesterday across Alberta and Saskatchewan. In Alberta, Environment Canada posted a tornado watch for most of the central portion of the province, including Edmonton, for the development of funnel clouds and weak tornadoes from late in the afternoon into the evening. Slow moving heavy thunderstorms also produced decent rainfall with 20-40mm expected in Alberta and as much as 75mm or more in southern Saskatchewan where heavy rainfall warnings are in effect. Flash flooding was observed just south of the border in Montana. The system will slowly move northeast from Montana into Saskatchewan today and gradually weaken.
