Tornado, damaging wind risk in Ontario and Quebec; prepare in case of outages
Heat and humidity return to Central Canada, elevating the thunderstorm risk in both Ontario and Quebec Thursday. DON'T MISS: Several lines of severe thunderstorms are expected to develop as humidity and instability peak during the afternoon and evening hours. Key factors driving this weather include moisture, instability, wind shear, and a low pressure system acting as a trigger. While the main risks are hail, heavy downpours and potent, potentially damaging wind gusts, there is a chance of rotation and one or two tornadoes for parts of northeastern Ontario, Lake Huron-Georgian Bay shores and Quebec. Make sure you keep an eye on the radar––especially if you have outdoor plans––and stay aware of any severe weather watches or warnings issued in your area. Thursday: Severe storm threat bubbles up with the rising humidity and instability Southern and eastern Ontario will experience humidex values near 40°C during the afternoon, with dry conditions likely until storms develop in the evening hours. SEE ALSO: Timing: 4-5 p.m. Thunderstorm activity is expected to begin as early as 4–5 p.m. in northeastern Ontario and parts of Quebec, where severe weather has the highest confidence. Early-stage storm development may lead to isolated, rotating cells capable of producing tornadoes, particularly in Quebec. Heavy rainfall is also a significant risk, with totals exceeding 50 mm locally due to multiple storm cells passing over the same areas. Localized flooding is a concern. RELATED: 7-8 p.m. As storms mature, a transition to a more linear pattern is expected, increasing the likelihood of damaging wind gusts between 90–100+ km/h, particularly along Georgian Bay and Lake Huron Shores from 7–8 p.m. onwards. Late evening and overnight: Thunderstorms may reach the northern Greater Toronto Area (GTA) during the late evening or overnight hours, but will weaken as energy diminishes. DON'T MISS: Rainy periods could persist into Friday morning for parts of the GTA. WATCH: In a tornado warning? Here's what you should do Click here to view the video Signs of cooler weather for the August long weekend Early next week, conditions will stay mostly sunny, hot, and humid, accompanied by a chance of passing thunderstorms. A strong cold front is expected to sweep south through the region midweek, bringing a heightened risk of thunderstorms. By late next week, cooler air will settle in, with temperatures expected to remain below seasonal averages through the August long weekend and into the first week of the month. However, a return to significantly warmer weather is anticipated for the second week of August.

Drier air moves in after round of scattered showers across South Florida
Scattered showers and storms will move across South Florida on Thursday before drier air moves in just in time for the weekend. The chance of rain will be highest in the morning through the midday hours, with the potential for some heavy downpours and localized flooding. The atmosphere remains juicy and unstable due to an upper-level area of low pressure which has led to all the wet weather over the last few days. Afternoon highs will climb to the low 90s, but when the humidity is factored in, it will feel like the upper 90s and 100s. There is a moderate risk of rip currents along the Atlantic beaches and the UV index is extreme. There are no alerts or advisories for boaters over the Atlantic or Keys waters. Late Thursday afternoon, a plume of Saharan dust will begin to move and storms will push inland and to the west. The drier air and high pressure will bring drier, hotter conditions on Friday and through the weekend. It will be a scorcher due to the lack of rain and cloud coverage. Highs will soar to the low 90s and it will feel like the triple-digits. The National Weather Service may issue heat advisories. Early to middle of next week the chance of rain rises with the potential for passing showers and a few storms. The National Hurricane Center is monitoring a trough of low pressure over the north-central Gulf that has a low potential (10% chance) of development as it moves generally westward across the north-central portion of the Gulf. Regardless of development, this system is expected to bring heavy rain and the potential for flooding along the Gulf coast.
