While Atlantic Canada will feel fairly seasonal on Thursday and Friday, there will be several rounds of showers hanging on to a slow moving trough. Once Hurricane Laura dissipates, remnant moisture will track into the region this weekend. Saturday afternoon is the earliest arrival time for this moisture, which could create heavy downpours with some areas seeing upwards of 50 mm. Details and timing, below.

THURSDAY AND BEYOND: MORE RAIN, POTENTIAL FOR SIGNIFICANT WEEKEND SYSTEM, LAURA REMNANTS
Thursday looks to be another unsettled day across western Newfoundland and the Avalon, as there will be wraparound showers from the behind the front.
Southwestern Newfoundland can expect the heaviest rainfall totals, with 50-75 mm expected. Widespread totals of 50 mm is forecast for much of the the western coast, with 30-50 mm in central areas and 20-30 mm for southern areas including parts of the Avalon.
Daytime highs won't stray far from Wednesday's, with below seasonal temperatures again, sitting in the low- to upper-teens across the province.
Beyond, cooler weather is ahead into the late week, though for the Avalon it will be near-seasonal. Meanwhile, forecasters are watching the weekend, when a significant system is set to track into the region, with the potential for more widespread rain and strong winds.
"We are closely watching to see if the remnants of Laura merge with the system, which would bring the risk for high winds and locally heavy rain for parts of the region if the track of the storm is far enough to the north," The Weather Network meteorologist Dr. Doug Gillham says.
The Weather Network meteorologist Tyler Hamilton adds that it is possible for some areas to see upwards of 50 mm of rain in the heavy downpours this weekend.
