Summer-like weather is making a comeback to southern Ontario as the week wears on, with temperatures climbing into the upper 20s and humidex values returning to the mid- to upper 30s by the weekend.

Remnants from the life-threatening Hurricane Florence are expected to track north towards the region, but there’s an unusually low confidence in the forecast with two very different scenarios at play.

Playing a supporting role in this week’s weather across the Great Lakes is Hurricane Florence. Though southern Ontario won’t see any direct effects from this powerful storm, there are some distinct connections between the landfalling hurricane and our weather pattern over the next 7 to 10 days.

Temperatures will be climbing over the next several days, as a powerful high-pressure system builds in over New England and southern Quebec. This feature is part of the same anomalously strong western Atlantic ridge that has steered Florence’s track towards the U.S. eastern seaboard and prevented the hurricane from recurving out to sea.

Along with steering Florence, the flow around this ridge will be pumping humidity-laden air back into the Great Lakes region, causing temperatures to rise steadily through the week to near 30 by the weekend – making a very stark contrast to this past weekend’s cool temperatures and cloudy skies.
