Wednesday, September 15th 2021, 12:45 am - Tornado warnings and watches were dropped in Ontario earlier Tuesday evening but the threat of severe weather continues overnight Tuesday as a line of storms pushes its way into eastern sections.
After a stormy Tuesday afternoon and evening that yielded tornado warnings for parts of Ontario, a line of nocturnal storms continues to push east after sweeping through the Greater Toronto Area (GTA), which prompted severe thunderstorm warnings in the latter but have since ended. They are now heading towards eastern Ontario and Quebec through the rest of the overnight hours. Severe thunderstorm warnings remain in eastern and southeastern Ontario, but will drop once they depart the province. Storms may bring strong winds, heavy rain and large hail. Conditions will greatly improve by Wednesday morning. More on what's to come with the severe storms, and what lies ahead for the rest of the week, below.
TUESDAY NIGHT: SEVERE STORMS TREK EAST, CONDITIONS WILL IMPROVE BY WEDNESDAY MORNING
After racing through the GTA in the early overnight, the line of severe storms are making their way into southeastern and eastern Ontario. Severe thunderstorm warnings continue for the latter areas as they push into and through the regions overnight. Storms are likely to bring strong winds, hail and frequent lightning as they pass through.
The storms will also reach southern Quebec through the overnight period.
