Toronto and the Greater Toronto Area (GTA) are bracing for severe thunderstorms combined with heavy rain over the next few days. A recent severe thunderstorm watch has been issued by Environment Canada for several regions including Toronto, Hamilton, Halton, Peel, and Niagara.
Weather Forecast: Thunderstorms and Heavy Rain Expected
Forecasters predict that the storms will commence tonight and persist through Tuesday. Residents should prepare for torrential downpours, frequent lightning, and the possibility of hail. Rainfall amounts could reach up to 50 millimeters in various areas.
Temperature Fluctuations
The upcoming days will feature significant temperature variations in Southern Ontario. After starting the week with temperatures close to 20°C, the forecast indicates a downturn as temperatures could crash to around 9°C overnight. This fluctuation will set the stage for a mix of weather conditions, ranging from heavy rainfall to freezing rain possibilities.
Storm Predictions for Tuesday
Tuesday is expected to be the most active day. Warm, unstable air is anticipated to push temperatures up to 17°C, with winds gusting from the southwest at speeds of 30–60 km/h. Rainfall amounts are predicted to exceed 10–20 millimeters, as the risk of thunderstorms lingers throughout the day. This weather system is expected to tap into a significant moisture source, leading to localized downpours.
Midweek Weather Changes
Wednesday will serve as a transitional day. After Tuesday’s storms, the weather will temporarily calm, presenting sunny breaks with a high near 8°C. However, colder air moving in from the north may bring freezing rain or ice pellets by Wednesday evening. This phenomenon is typical for early spring and could lead to slippy conditions overnight into Thursday.
Persistent Rain and Cold Front
On Thursday, conditions are forecasted to shift again, with colder rain expected throughout the day. Anticipated rainfall amounts are between 15 to 30 millimeters. Temperatures are likely to remain close to 3°C, and easterly winds at 20–50 km/h will contribute to a raw, chilly atmosphere.
