"High pressure slides through Ontario for the next few days, with pleasant skies, drier conditions and warmer temperatures forecast," says Weather Network meteorologist Brian Dillon. "Humidex values will be near 30-32 on Saturday and Sunday."
According to Dillon, the next chance of thunderstorms in the Nickelbelt, southern and eastern Ontario will be on Monday as the next cold front pushes through the area.
3. Large hail, gustnado hit southern Alberta
"Although Calgary was not directly affected by a thunderstorm, there was a report of a gustnado near Stony Trail and Metis Trail and northeastern Calgary," says Environment Canada in a weather summary.
According to EC, gustnadoes are short-lived, low-level rotation associated with the outflow winds from a thunderstorm.
