After a cool start to spring, it may be difficult to believe that the GTA is in for summer heat and even humidity on Wednesday.

680 NEWS meteorologist Jill Taylor said the temperature is expected to hit 29 C under mainly sunny skies. The heat will intensify throughout the day as the humidex hovers around 37. There is a chance of showers or thunderstorms after 9 p.m.

Taylor said while it will be a hot day on Wednesday, it likely won’t be a record-setting one. The record for a May 17 at Pearson Airport was 34.4 C (without the humidex) set in 1962.

However, it could be the hottest day of the year so far at Pearson. The temperature would need to surpass 25.7 C, which was reached on April 27.

The heat will stick around on Thursday with a high of 29 C but it will feel like 34 C with the humidity. There is also a slight chance of showers or thunderstorms.

As Friday arrives, temperatures will be cooler for the Victoria Day long weekend. The highs on Friday and Saturday will be in the mid-teens with sun and cloud.

Sunday should be the warmest day with a high of 21 C but it will be cloudy with a chance of showers of thunderstorms for the evening. Cloudy conditions continue on Monday with a high of 18 C.
