The heat will remain in Atlantic Canada for one more day before being swept away by a cold front. Temperatures won’t drop dramatically on Tuesday, but they should make conditions more comfortable for those who didn’t enjoy the heat. However, there could be severe weather for parts of the Maritimes on Monday before cooler air moves in for the rest of the week. More on what to watch below.

Monday: the last day of heat arrives with the risk of strong storms in parts of the Maritimes
Monday will be the fifth day of temperatures in the 30s and values similar to the 40s for parts of the Maritimes. But that will change on Tuesday after a system passes through.
The start of the week will also see the arrival of a cold front after it develops in Maine and spreads across New Brunswick and Nova Scotia. Strong winds will be the primary concern with any severe storms that develop, possibly as a squall line.
Ahead of the front, isolated storms forecast for southern Nova Scotia and the Bay of Fundy will spoil some Monday afternoon plans.
Another day of high temperatures close to 30 °C and 30 degrees lower in the Maritimes. Some spots could even reach the mid 30s. Humidex values will reach the upper 30s and even near 40s.
On Sunday, San Juan Airport recorded a temperature reading of 30 degrees for the first time in 3296 days.
Across the Gulf of St. Lawrence, temperatures will reach 30°C in Gander, NL, and St. John’s will continue its unusually warm summer with highs in the upper 20s.
Beyond Monday, humidity will drop for the rest of the week, but temperatures will remain in the upper 20s for the rest of July.
