At approximately 4:00 pm MDT on June 9, 2017, a brief tornado was observed 20 km north of Mannville. Environment and Climate Change Canada received multiple reports and photos. A dust cloud was seen at the base of the funnel, however there were no reports of damage therefore, this tornado has been given a preliminary rating of EF0.

Heat warnings are now in place for ON as robust upper ridging makes it’s move into the region over the next few days, ahead of a rather modest cooling trend later in the coming week. This near-term pattern and expected transition could be marked by episodes of severe weather.
The extended range could feature a return to more of a western ridge and troughiness through the central portion of the country if guidance is correct.
