The long-weekend weather forecast in the big temperature area shows that only Sunday is expected to usher in short and sunny weather during the Victoria Day holiday. Matt Rodney, a meteorologist from Environment Canada, pointed out that due to the influence of unstable airflow, there will be continuous rainfall, and there will still be showers during the day and thunderstorms at weekends. The rainfall at night is expected to reach 10-15 mm. After the rain gradually stopped on Sunday morning, it turned sunny and cloudy, and the temperature rose to 16 degrees Celsius, making it the best time for outdoor activities. However, in a new round of shanghai dawn on Monday morning, the whole day rainfall may reach 15-20mm, until the rain weakens on Tuesday.
