Weather synopsis

Beginning tomorrow, a warm front from the Great Lakes will move into 
Quebec. Behind the front, winds will become southwesterly and usher 
in a warm and humid air mass.

For now, it seems that this situation will persist until the end of 
week over a great part of the southwest and the centre of the 
province. The maximum temperatures over these regions could exceed 
the 30 degrees, as the humidex values will climb generally between 35 
and 40. These values could even exceed the 40 mark over areas more to 
the south Thursday.

As this hot spell air settles itself over the province of Quebec, the 
probability of thunderstorms will increase and some could be strong.

This bulletin is only an advisory notice and the public is advised to 
follow present and future warnings issued by Environment Canada.
