Scattered storms across Atlantic Canada, changeable pattern continues

Wednesday, August 12th 2020, 7:48 pm - Temperatures are expected to fall to the low 20s by the weekend, which will bring relief from the hot conditions that Atlantic Canada saw earlier this week.

A cold front pushing through the region will bring the potential for isolated thunderstorms across Atlantic Canada on Thursday, but many will see dry conditions. The heat will ease as the weekend approaches, but meteorologists warn that the unsettled trend will continue. Scattered showers are expected on Friday and will continue into the weekend, but could miss regions that are in need of a heavy rain. Details and timing, below.


WEATHER HIGHLIGHTS
