This week’s weather: Humid with a bit of sunshine and rain in Ontario

This week will bring a mix of cloudiness, rain, and sunshine, but some hot and humid weather will hit first.

Environment Canada has issued a multi-day heat warning for southern Ontario.

Daytime highs are forecasted to rise to 31 degrees Celcius, with humidex values ranging between 35 and 38.

As of today (July 7), it will be mainly sunny, with temperatures reaching 27 C.

By the evening, temperatures will drop to 17 C and the skies will become partly cloudy, clearing overnight.

Monday is anticipated to be mostly sunny with some cloudy periods. Temperatures will soar to 30 C, but with the humidex reaching 38, it will feel significantly hotter.

The UV index will hit very high at level 9. Environment Canada advises protecting your skin when the UV index is three or higher, particularly between 10 a.m. and 4 p.m

Additionally, Health Canada says that if outdoors, individuals should seek shade, wear protective clothing and hats, apply SPF 30 or higher sunscreen, avoid tanning, use UV-protective sunglasses, and stay hydrated throughout the day.

Environment Canada notes on its website that those affected by the heat warning are urged to drink plenty of water regularly, even before they feel thirsty, to decrease the risk of dehydration. Thirst is not a good indicator of dehydration.

As the evening approaches, the skies will gradually become cloudy with a 30 per cent chance of rain, potentially bringing overnight thunderstorms. Temperatures will slip to 18 C.

Tuesday will bring another round of 30 C temperatures with a mix of sun and clouds and a 30 per cent chance of rain— though the exact amount is unknown. Evening temperatures will dip to 17 C, with skies becoming predominantly cloudy and a 30 per cent chance of rain returning.

A cooler airmass is expected to arrive Tuesday night, bringing relief to most of the region.

Wednesday and Thursday will be similar, with mainly cloudy skies and a 60 to 70 per cent chance of rain throughout the day. Daytime temperatures will be cooler than the beginning of the week, reaching 22 C and dropping between 16 C and 18 C at night.

Sunshine will return on Friday and Saturday, with occasional clouds. Daytime temperatures will hover between 28 C and 29 C, dropping to 17 C in the evening.

The following week, it appears that Monday through Wednesday will see plenty of rain and possible thunderstorms. However, temperatures may remain on the warmer side, sticking between 25 C and 29 C.

Sunshine will return from Thursday into the weekend, bringing with it some cloudy skies. Evening temperatures will shift between 15 C and 26 C.
