Conditions conducive for rotating storms in parts of the Maritimes
Before temperatures take a dip Tuesday, a cold front could trigger severe storms in parts of the Maritimes Monday including the possibility of rotating storms in New Brunswick. There is the potential for one or two tornadoes.
The heat will hang on for one more day in Atlantic Canada before being wiped away by a cold front. Temperatures won't drop drastically come Tuesday, but should make conditions more comfortable for those who didn't enjoy the heat. However, there could be severe weather on Monday for parts of the Maritimes include the risk of rotating storms in parts of New Brunswick, so one or two tornadoes are possible.

Monday: Final day of heat comes with risk for severe storms in parts of the Maritimes
Monday will be the fifth day of temperatures in the 30s and feels-like values in the 40s for parts of Atlantic Canada. But that will change by Tuesday after a system moves through.
The start to the week will also see the arrival of a cold front after it develops in Maine and sweeps across New Brunswick and Nova Scotia. Strong winds will be the main concern with any severe storm that develops, possibly as a squall line.
In New Brunswick, conditions will become favourable for rotating storms late afternoon, so one or two tornadoes will be possible.
Ahead of the front, isolated storms expected across southern Nova Scotia and the Bay of Fundy will spoil some Monday afternoon plans.
One more day of high temperatures near 30°C and into the lower 30s across Atlantic Canada. A few spots could even reach the mid-30s. The humidex values will hit the upper 30s and even near 40.
On Sunday, St. John's airport logged a 30-degree temperature reading for the first time in 3,296 days.
Across the Gulf of St. Lawrence, temperatures will reach near 30°C for Gander, N.L., and St. John’s will continue with its unusually warm summer with highs in the upper 20s.
Beyond Monday, the humidity will drop for the remainder of the week, but the temperatures will remain in the upper 20s for the remainder of July.
