Thunderstorms overnight, during morning commute in the GTA

A cold front is bringing showers and thunderstorms to the Greater Toronto Area (GTA) overnight and during Wednesday's morning commute. CityNews Chief Meteorologist Natasha Ramsahai explains that the rain will begin moving in from the tip of the Bruce Peninsula around evening time and make its way to Toronto after midnight, continuing into Wednesday morning.

According to Ramsahai, the cold front is intensifying the atmospheric instability, causing showers and thunderstorms to form. It is expected that the storms will start hitting the north end of the GTA around 3 a.m. to 4 a.m. Wet roads and sidewalks are anticipated to persist until roughly 8 a.m. during the early part of the morning rush.

Although there will be a brief respite in the morning, pop-up rain or storms are still a possibility in the early afternoon. By 3 p.m., outdoor activities can resume as the weather clears up, with temperatures hovering around 26 C on Thursday and Friday. Although the cold front bringing tonight's storms won't necessarily result in a drop in temperature, it will bring a fresh northwest wind and increased humidity.

However, the weather is expected to be unpredictable for the weekend, with a dry morning on Saturday, followed by rain and thunderstorms that may continue intermittently through Sunday. Ramsahai advises that outdoor activities might need to be adjusted, but notes that Saturday morning, at least the first half of the day, is the best time to enjoy outdoor activities during the weekend.
