A recognized element to train disrupted time clings to Quebec and plans to visit certain sectors on Saturday and others on Sunday. Forecast.
A risk of thunderstorms or a routine day
Since the beginning of July, thunderstorms have been part of the routine of most of the Quebec sectors. Could this weekend be the exception to the rule? Not quite, but there are nuances to do! Saturday is generally a beautiful day overall. However, for a corridor which extends from Abitibi-Témiscamingue to the North Shore, there could be precipitation and even some thunderstorms. The sectors targeted by visiting these potential thunderstorms can be reassured: the stormy activity of the day has nothing to do with the violent time sequence that beautiful province has just crossed! A hollow could however generate a thunderstorm strip on Saturday afternoon.
This could move and continue until evening and even on the night of Saturday to Sunday for the eastern sectors of Quebec, such as the Gaspésie, the Saguenay-Lac-Saint-Jean, as well as the North Shore.
More classic thunderstorms
On Saturday, the slightly more disturbed weather should manifest more in the form of showers than thunderstorms, with amounts of rain possibly greater in places. “There could also be strong gusts. We are not talking about violent time, however, because the indices are very limited in comparison with the more intense events of the last days. Low shear, low energy, moderate instability due to a hollow and also a little humidity in the atmosphere, “said Nicolas Lessard, meteorologist.
To be continued on Sunday
Then, the precipitation should start for the south of the province late in the evening on Saturday or early during the night from Saturday to Sunday, especially in Montreal and Quebec. “Sunday could potentially be a spoiled day due to another hollow. This one should be quite stronger on the side of Maine, so Quebec would avoid the worst. There could still be important accumulations of rain along the St. Lawrence Valley, ”says Nicolas Lessard. It is a fairly wide mass of precipitation, but, once again, we do not provide violent thunderstorms on our side of the border with the United States.
Thus, even if the beautiful province is entitled to the start of the weekend with rather quiet appearances, it should never be forgotten that appearances can be misleading!
