PLAN AHEAD: Warm or wintry? Halloween weekend holds a mixed bag for Canada
Accumulations are much trickier closer to the Trans-Canada as a touch of warmer air aloft will force a transition to ice pellets and freezing rain for a time through Friday.
The greatest risk for ice accretion from freezing rain will fall along and south of the Trans-Canada, bringing a potential glaze of ice to Geraldton, Calstock, Nipigon, and Manitouwadge.
Winds blowing off Lake Superior should be just warm enough to keep precipitation plain old liquid rain around Thunder Bay.
Motorists planning to travel in these impacted regions are urged to exercise caution as driving may be treacherous at times.
This is all quite the contrast from the southern half of the province, where overnight lows may even be warm enough to break some October records this week.
