The season begins in force. Forecast.
Return thunderstorms
An atmosphere context that strangely resembles that of Tuesday is emerging for Friday day. The ingredients are again gathered for the formation of thunderstorms. A contrast between two air masses could cause an uprising. In addition, a mild and humid air rise should be an energy tank to power these stormy cells.
A system and a front
Friday afternoon, a system followed by a cold front could generate stormy activity. If we compare with Tuesday’s situation, temperatures should not reach such high thresholds. The humidity intake would also be less intense with a dew point from 10 ° to 15 °. Therefore, there will be less energy available.
Other sectors
Depending on the models, other sectors are targeted by these stormy cells. Indeed, the system could generate thunderstorms south of the river. Estrie, Montérégie and Bois-Francs may see action on Friday. Note that heavy rain, strong winds and small hailstones represent the main threats.
Active season
Note that April rarely puts days days with thunderstorms. On average, the province observes four. This year, Quebec has had more and May promises to be active. As heat and humidity take stock, there is an increase in the number of days with thunderstorms. In May, Quebec recorded a dozen.
