High pressure that is sitting over New England will create some changeable conditions across Ontario this week. A southerly flow will bring heat to the region and Environment Canada has issued widespread special weather statements that warn of the hot and humid conditions expected on Tuesday. Details and timing, below.

THIS WEEK: FLIP-FLOPPING TEMPERATURES, COOLER START TO JUNE

Summer-like warmth will return to southern Ontario this week and Environment Canada warns that several regions will see maximum temperatures of 31°C and overnight lows of 20°C.

“These conditions pose a health risk when you are not used to the heat. Everyone is at risk from heat, especially older adults; infants and young children; and people with chronic illnesses. You are advised to 1) drink plenty of cool liquids before feeling thirsty; and 2) keep cool by dressing for the weather and spending a few hours each day in a cool place,” states Environment Canada.

With the resurging heat and humidity, there will be enough instability to allow for some showers and even some thunderstorms. The risk looks to be non-severe for many areas, but some regions could see strong winds, heavy downpours, and small hail where the storms strike.

One contributor to those unsettled conditions will be a system moving in from the Prairies that will also fuel some strong winds, in the 50-70 km/h range.

Relief from the humidity will come on Wednesday. Another temperature dip is ahead for the late week and many areas will see below-seasonal temperatures on Friday that will be under 20°C.

Conditions will eventually warm back up again in time for the weekend for most people, but a preliminary look ahead to the first week of June shows a period of cooler weather, so the start of meteorological summer could feel more like spring.
