As the fall season approaches, Maritimers have been enjoying a late summer blast of heat.
“That’s because a warm air mass is in place,” explains Dayna Vettese, a meteorologist at The Weather Network. “There’s also a little bit of a ridge in the jet stream.”
According to Vettese, a jet stream is the division between warm and cool air, with cool air to the north, and warmer to the south.
“The jet stream over the Maritimes is causing them to have warm temperatures, as well as a warm south westerly flow with humid air coming from the south.”
Temperatures have been hovering in the mid-twenties, feeling closer to 30 with the humidex. However, that warm spell should end by late Thursday when a cold front moves in.
That system is expected to merge with Tropical Storm Maria, and could cause cooler temperatures into the weekend. Extra moisture from the storm could also bring heavy rain and strong winds to Nova Scotia and Newfoundland through Saturday.
