Rain is forecast for Thursday across Toronto and the surrounding Greater Toronto Area, with clouds moving in after a mild start to the day. The precipitation will be followed by a noticeable drop in temperature, leading to a risk of frost over the weekend while periods of sunshine break through the clouds.
Unsettled weather patterns are responsible for the sharp temperature decline, shifting the forecast from wet conditions on Thursday to cooler, sunnier weather on Friday through Sunday. Residents can expect the chance of frost as temperatures fall, despite intermittent sunshine during the weekend.
