It is as if the thunderstorms were tested on these sectors. Forecast.
In short:
-
The risk once again present for the West;
-
The ingredients gathered for violent time;
-
Supercellules and possible rotation.
Hot and humid
Everyone is aware; It has been hot in Quebec for several days. To tell the truth, the province is at the heart of a rare heat wave that could last up to seven days in southern Quebec and which could be among the most intense recorded in Montreal. The other regions are not to be outdone: heat records were broken Sunday in many sectors, especially in Chibougamau. It goes without saying that these elements fuel the risk of thunderstorms and it is the western regions that could undergo the wrath on Monday.
Like the last months
The west of the province has been the scene of thunderstorms on many occasions since the start of the season and the day on Monday will be no exception. In the afternoon, cells could train in Abitibi-Témiscamingue and generate torrential rains, large hailings and powerful gusts. On the outskirts, the risk will be less, but still present. As for the southern, center and east regions, thunderstorms should be held out.
The manager
This risk of violent thunderstorms is a graciousness of the passage of a cold front in the northwest of the province. Thus, all the ingredients will be gathered for particularly active time from Témiscamingue in Chibougamau until evening. It is at the front of the hollow that this instability conducive to thunderstorms will be created. The air will be full of energy and humidity and we even speak of a possibility of supercellules and rotation. Let’s not forget that August rose in second place in the most stormy months of the year in Quebec.
