Heat warning in effect

The weather, currently.

The Heat Warning continues.

Temperatures will be well above seasonal with humidex readings approaching yet again near 40°C. Wednesday morning will start under mainly sunny skies and a wake-up temperature of 23°C, feeling like 29°C. A mix of sun and clouds can be expected overall for the day, with a high of 31°C, feeling like 40.°C There will be a breeze from the SW at  20-40km/h, and the UV index will be 10 or very high. An approaching cold front will help trigger some intense thunderstorms and bring some rain showers by late evening in the GTA. It appears it will be a broken line of storms, with the greatest risk of severe and damaging weather occurring in the Windsor, Sarnia London area and also parts of cottage country including Barrie. These storms will likely deliver, hail, strong winds, and even the possibility of tornadoes.  Again that risk primarily -  but not exclusively - will be SW and North of the city. For those who are camping etc, please keep an eye to the sky

Wednesday night: Scattered rain showers and isolated thunderstorms ending early overnight with partial clearing by dawn and a low of 21°C, feeling like 25°C.

Sidenote: It is important to stay hydrated during extreme heat events. The symptoms of heat stress include dizziness/fainting; nausea/vomiting; rapid breathing and heartbeat; extreme thirst; decreased urination with unusually dark urine.

What you need to know, currently.

The June 2022 Global Climate Report came out a few days ago.

The report said that the global surface temperature for June 2022, which was 0.87°C (1.57°F) above the 20th century average, was the sixth-highest for June, in the 143-year-long recorded history. This month was also 0.08°C (0.14°F) cooler than the warmest June on record, which was in 2019.

June had some very warm temperatures across the Northern Hemisphere with several places across Europe, the Middle East and northern Africa experiencing daily maximum temperatures over 35°C (95°F), with some places reaching 50°C (122°F) during the first week of the month. North America and Africa had their seventh and tenth-warmest June on record, respectively.

The extreme heat that suffocated much of Asia, and now Europe, led to both continents having their second-warmest recorded June as well.
