THUNDER BAY – Sunday’s weather may make it a sloppy and less than Spring-like start to the new season. Environment Canada is reporting, as of 3:45AM that, “An approaching Alberta clipper like low is forecast to track east from North Dakota to the Ontario – Minnesota border by this evening.
Ahead of this low rain and snow have already spread to Northwestern Ontario last night, with snow accumulation of 5 to 10 cm reported over areas from Red Lake to Sioux Lookout and east. Locales near the Minnesota border will receive more rain than snow as the south side of the low brings milder air to the regions.
As the low sails east over the upper Great Lakes tonight, an expanding area of snow will spread into Northeastern Ontario.
Precipitation will be various mixtures of wet snow and rain near the upper Great Lakes which will limit snowfall accumulations.
Some freezing rain is also possible especially over regions south of a line from Sault Ste Marie to North Bay as wet snow turns over to rain. Inland across much of Northeastern Ontario latest indications are suggesting a possible 10 cm snow event by Monday morning.
Motorists should be prepared for deteriorating winter driving conditions due to low visibility in heavier snow and untreated roads becoming snow covered and slippery.
Environment Canada is closely monitoring this situation. If this low becomes stronger than expected, snowfall warnings for parts of Northeastern Ontario are not out of the question.
