High temps with wind and storms possible

London area forecast for April 21, 2025

The temperature continues to climb Monday with strong winds in the afternoon — gusting upwards of 80 km/h.

“It’s all a part of a low-pressure system moving throughout our region this evening,” said CTV News London’s Reta Ismail. “And as a result, some pop-up thunderstorms are possible — non severe right now.”

A cold front will push through tonight, but it won’t really impact our temperatures, said Ismail.

“They’re actually going to remain at or slightly above what is normal this time of year, which is about 13 C.”

There is a line of storms being tracked in the region that could result in a special weather statement currently in effect, being upgraded to a severe thunderstorm watch or warning.

High pressure moves in for Tuesday, which means plenty of sunshine in the forecast.

The high tomorrow is right were it’s supposed to be this time of year, and we’ll hold on to that sunshine into Wednesday under a nice mix of sun and.
