Share

It’s been a busy start to the week for weather with the Forest City shattering a 58-year-old temperature record on Monday.

According to CTV News London’s Meteorologist Julie Atchison, on Monday the Forest City smashed the previous temperature record for March 4 of 15 C that was previously set in 1966.

On Monday, the temperature reading at London’s airport reached 19.6 C.

London wasn’t the only city to shatter weather records, with Windsor, Sarnia and Wiarton also breaking records. Atchison said Windsor was also the warmest spot in Canada, reaching a high of 22 C.

The weather will take a bit of a shift on Tuesday however, with a cold front bringing a 60 per cent chance of rainfall and possible thunderstorms to the region.

With the temperature peaking at approximately noon and then subsequently falling throughout the day, Atchison said Tuesday will be another “mild” day with the high expected to reach 16 C.
