Tuesday, June 14, 2022, 8:56 PM – The risk of storms and humidity will increase this week in southern Ontario, and some places will likely see humidex values in the mid-1940s on Thursday.
The rest of southern Ontario in the face of heat and the potential for storms will come to an end. Some areas in the southwest could see storms, possibly also strong, on Tuesday night before the heat and humidity return for Wednesday and Thursday. Wednesday will be a situation of rising or falling storms, much depending on the confluence of many factors. On Thursday it will have a similar configuration of heat and storm, with humidex values that will go up to the 40s in some areas.

TUESDAY NIGHT / WEDNESDAY: CONDITIONAL STORM THREATS As heat builds up
As the heat returns to southern Ontario, so does the possibility of storms.
There is a possibility that parts of southwestern Ontario may be awakened by Mother Nature’s alarm clock on Tuesday night in the early hours of Wednesday morning.
There is a risk that storms will develop during the hours of Tuesday night from the shores of Lake Huron and then head south to the shores of Lake Erie.
Some storms could develop and become a little stronger with the main threats of hail and strong gusts of wind.
On Wednesday, there is another risk of storms. However, it is a bit of a conditional threat that will leave most without seeing storms or rain.
Storms have a chance to unfold along the lake breeze near Lake Huron and travel east. These storms could become very strong, producing heavy hail and strong gusts of wind. The hail could reach the size of a golf ball.
This is a very complicated forecast, so there is also the possibility that no storms will develop, leaving everyone in the region with hot, humid and sunny conditions.
Temperatures will warm to 20 degrees above average in most of southern Ontario on Wednesday. Southwestern sections could even reach and exceed the 30-degree mark, with values similar to 44 in Windsor. Elsewhere, widespread wetland values are expected between the 1930s and 1930s.
THURSDAY AND BEYOND: THE POTENTIAL OF WEATHER, HUMIDITY AND TEMPERATURES WILL RELAX THE FATHER’S DAY WEEKEND
The risk of severe to severe storms will re-emerge on Thursday in southern and eastern Ontario with localized torrential rains and the potential for harmful winds. However, most of the day will be free of rain and some places may miss the storms.
DON’T MISS: Is Father’s Day Coming? Consider these five gifts
Thursday will be even hotter than Wednesday, with high temperatures ranging from the upper 20 degrees to the lower 30 degrees. Humidex values will be in the upper 30s and lower 40s. The timing of storms will have a major impact on high temperatures.
Cooler, near-seasonal conditions return on Friday, marking a great day for southern Ontario, but showers and thunderstorms are possible in the eastern areas. A “sunny” weekend is approaching in southern Ontario. Abundant sun, low humidity and pleasant temperatures, although degrees cooler than seasonal ones. There will be time for Father’s Day.
Beyond that, a warming trend is forecast for early and mid-next week as the heat wave in the midwestern U.S. tries to spread to the region. There is uncertainty about where the boundary between tropical heat and humidity will be compared to more comfortable conditions.
Southwestern Ontario will probably have a couple of days of excessive heat with a humidex by the 1940s. This pattern favors a pair of MCS (mesoscale convective systems) near the warm front. Cooler weather is expected to return on weekends and weekends.
